A given oil filter might truthfully say it is: 100% efficient at 30 microns, and nothing that size gets through to the engine, 95% efficient at 25 microns, but here 5% of that size gets through, 90% efficient at 20 microns, but here 10% of that size gets through, 85% efficient at 15 microns, but here 15% of that size gets through, 80% efficient at 10 microns, but here 20% of that size gets through, 75% efficient at 5 microns, but here 25% of that size gets through. And to add insult to injury, you could inspect your lifters one day when they look and feel just fine, and the next day they can suffer metal fatigue failure and things go south.
So, using a battery charger to keep the battery fully charged, becomes important. With all that in mind, let’s see how true or false the claims made by High Mileage (HM) motor oils are.
It is only the poorly designed “Direct Injection Only” engines that can benefit from an Oil Catch Can. So, the claims made on motor oil bottles and websites would only be taken as truthful, by gullible people who are not Technically savvy.These zinc lover critics may mean well, but they really DO NOT know what they are talking about. • And if a vehicle is being driven very little, then changing the oil once a year, is recommended. However, the highest quality oil filters have their bypass valves located next to and around the threads. Is it possible that the Diesel oil fans somehow know more than the Oil Companies’ Chemical Engineers and Chemists? But, now we know that the hype about great wear protection was nothing more than false advertising snake oil. I am only the messenger. This is an issue to take very seriously, if you want to provide your engine with the best possible lubrication protection. Mainly, predation has been reported on the cottontail rabbits. Chlorine and additive package incompatibility has a possible risk of creating damaging bearing corrosion problems. And it claims superior wear protection and high temperature stability, both of which proved to be true in my Engineering tests. [43][46] Total length of full-grown birds can vary from 35 to 46 cm (14 to 18 in) in males and 42 to 50 cm (17 to 20 in) in females.
Reader Beware!!! So, I DO NOT promote any particular brand. This range is hot enough to quickly boil off the normal condensation that always forms during cold engine start-up, before that water dilutes the oil. And this oil did have a 13% drop in capability. But, that is simply NOT true. Best Coolers For Camping - [2021 Reviews The Science is what tells us how these oils perform. Not yet. Amazon has none of these grow kits, I just checked each link. I’ve done “failed” rod bolt “Strength Analysis” on two smaller very high revving engines, after the fact, to take a look at why they failed.
That is why very serious Race efforts will generally use watery thin oils in their engines. 10W30 Champion Racing Oil, synthetic blend = 67,239 psizinc = TBDphos = TBDmoly = TBD..222.
.The detergent and TBN levels are so very low here, that this oil should most likely be changed after every outing, before those components are totally exhausted. So, let’s see how the real world testing above, supports those claims. You can only find that information here in my Blog, because no one else performs detailed evaluations and comparisons like I do here. 4. 15W50 Mobil 1, API SN synthetic = 70,235 psizinc = 1133 ppmphos = 1,168 ppmZDDP = 1100 ppm, 22. So, let’s take a look at the wear protection these oils and several other Break-In oils, actually provide, and see how they rank just among themselves, according to their “Load Carrying Capacity/Film Strength” psi value. It has been replaced by a new formula version that now has GM dexos 1 approval.
This might work for those who have the vehicle inside, and have a decent size battery charger that has a 2A trickle charge setting, that is of high enough quality that they are not concerned about leaving it charging unattended 24/7. And if you select a highly ranked oil from my wear protection ranking list, no matter how much zinc it has, with no aftermarket additives, you won’t even have to perform any special break-in procedures. This data will tell us once and for all, what the Oil Companies would not, and that is, whether the oils are formulated to “allow” wear or “prevent” wear.
.The oils I have ranked, were all tested at a representative 230*F operating temperature..But, I have also tested various motor oils at 275*F as well as 325*F. What I found was that going from 230*F to 275*F, the wear protection capability of the oils tested, dropped by only about 12% on average. Valvoline 85W-140, GL-5 hypoid extreme pressure gear oil, intended for AUTOMOTIVE differentials = 128,221 psi.
But, as the piston moves downward, the piston skirt scrapes off excess bulk oil, and the lower oil ring of a multi-piece oil ring, scrapes additional oil off the cylinder wall like a squeegee scraping water off a windshield.
So, they are actually saying their filter does not filter very well.
The oil viscosity has turned out to be nearly perfect for my purposes, having run it year round..===============.Hi K. It’s good to hear from you again. Now, back to a motor oil’s viscosity which is important regarding oil pressure, which in turn, shows us if that all-important incompressible hydrodynamic “liquid” oil wedge is being maintained, as mentioned above. Now we’ve seen that all the various recommendations above have only the interests of others in mind, rather than your best interest or your engine’s best interest in mind.
The biggest difference nowadays is whether or not the car’s normal factory intake system, and its normal factory exhaust system are used on the dyno. For people who feel compelled to run Diesel oil in gasoline engines, the 8 oils shown above are the best oils to consider for that.
Here’s why:The motor oil “Dynamic Wear Testing Under Load” I perform is WORST CASE torture testing. Here, the most frequently identified prey species was the Mexican Plateau horned lizard (Phrynosoma orbiculare) (11.5% of 191 prey items), followed by the northern flicker and thirdly the crevice spiny lizard (Sceloporus poinsettia) (10.47%, plus other unidentified spiny lizards making up a further 4.2% of the diet). Other ASTM tests called for testing at 302*F (150*C), which is WAY TOO HOT, and is also NOT representative of real world oil temperatures experienced by a running engine, where it spends 99% of its life. And that minor modification always took care of the issue for me.
CHEVRON DELO 400LE, 15W40 conventional, API CJ-4, CI-4 Plus, CI-4, CH-4, SM, SL, “Load Carrying Capacity/Film Strength” = 73,520 psizinc = 1519 ppmphos = 1139 ppmmoly = 80 ppmtotal detergent/dispersant/anti-deposit build-up/anti-sludge = 2205 ppmTBN = 8.0The onset of thermal breakdown is approximately 265*, 5. [80][103][104] They were once thought to be averse to cities and towns, but are now fairly common urban and suburban birds even when nesting. .1.
A., Causey, M. F., Mossop, D. H., Klucsarits, J. R., Robertson, B., Robertson, S., Mason, J., Maurer, M. J., Melvin, R. J., Dwason, R.D., Bortolotti, G. R., Parrish, J.W., Breen, T. F. & Bond, K. (2009). 0W20 Mobil 1 Advance Fuel Economy, API SN, dexos 1 approved, synthetic = 79,612 psiIt’s onset of Thermal Breakdown = 270*F..8. Greeney, H. F., Meneses, M. R., Hamilton, C. E., Lichter-Marck, E., Mannan, R. W., Snyder, N., Wethington, S.M. In these cases, most of the “failing wheel bearing sounding noises” started instantly or stopped instantly, when the tires were changed.
That is just the opposite of what some folks might think. Oil pressure is only a measurement of resistance to flow. [5][129] Multi-directional movements, even to the north as well as potentially any other direction, are more common than previously thought in this and other migratory raptors, which has been previously described as "inefficient and indirect method of 'homing'".
So, I had to make some careful calculations earlier, in order to end up as close to my target as possible.
At the time this oil was tested in fall 2013, it cost $22.45 per bottle. An Engineering Ph.D. who is the most highly respected Engineer, Car builder and Tech Guru on a popular Automotive Forum, asked me if he could include my Oil Testing Info in a list of Tech Papers written by well respected Industry authors, that he makes available to enthusiasts. And disappointingly, it did not feel very slick to the touch. That is why 5W30 oils can perform so much better than thicker oils in my wear protection capability testing). In fact, many of the modern low zinc oils provide BETTER WEAR PROTECTION than many of the traditional high zinc oils, which you will see in the ranking list below. This is a stout Street/Strip BBC Hotrod.
Now, looking at the typical range of available motor oils from thin to thick, you get a more complete picture of how thicker oils with their slower flow rates, drive temperatures higher, while increasing oil pressure. And for severe usage such as that, changing the oil every 3,000 miles is recommended. [92] On average, the number of trees per hectare in Arkansas were found to be 935.7. This Motorcycle Road Racing oil is from France and comes in liter bottles (slightly more than a quart). • Thicker viscosity oils drive up bearing temperatures, oil temperatures, and sump temperatures.
That way you have the best of both worlds.zinc = TBDphos = TBDmoly = TBDThis oil was tested Spring 2018. Solid roller lifters in general, are a fairly poor design, because, as mentioned above, they are subject to the non-stop jackhammer pounding as the lifters bounce around within their lash slop. This grow box is very beginner friendly and comes with endless email or phone tech support. But, I can share the following: The test methodology or test procedure I use at a representative operating oil temperature of 230*F, is a dynamic rubbing friction test under load, which generates a wear scar on a test specimen that is bathed in the oil being tested.
2. [28][138] It is thought that Cooper's hawks also avoid the Great Plains while migrating as well. But the FAA (Federal Aviation Administration) has established 80 psi input pressure as their standard for leakdown testing on piston aircraft engines. Again, even though the zinc/phos (ZDDP) level in particular, had dropped by about 25%. Air leaking out of the exhaust system indicates a leaking exhaust valve. With this higher yield Home grow kit, we have also included extra items to meet the demands of a larger grow set up: INCLUDES: The # of grow pots from 2 to 6, Two clip fans and saucers, Twice as many cementing jars and soil grow plugs. And the Tribodyn actually produced only slightly better psi numbers than Amsoil. As I’ve said before, there are no BAD oils here. (2008). This addition to the Handbook series is presented in five sections. The first sections covers basic and applied science, including biomechanics, the physiologic demands of volleyball, conditioning and nutrition. [5][60] Similar egg-laying dates, peaking around late April, are known in Arizona.
[2] As adults, they may be a solid blue-gray or brown-gray color above. 20W50 Castrol GTX, API SN conventional = 96,514 psizinc = 610 ppmphos = 754 ppmmoly = 94 ppm..88. So, all motor oils are the same in terms of preventing wear at the rod and main bearings when the engine is running, as long as that incompressible hydrodynamic “liquid” oil wedge is maintained.
[35] The purpose of bright eye color in the hawks may be correlated to feeding stimulation of nestling hawks (i.e.
He’s managed to get by with this, so he thinks he has it all figured out.
We no longer have to accept that as the cost of doing business, because we can do far better now. Its actual viscosity/thickness is “thicker” than 20W50 motor oil. In fact, it is quite clear that most of the time, they don’t even bother to read the information I provide.
An oil’s wear protection capability is determined by its proprietary additive package, which is what contains the extreme pressure anti-wear components.
Hiraldo, F., Delibes, M., Bustamante, J., & Estrella, R. R. (1991). However, I don’t do things just because everyone else is doing it. I suggest you consider the following list “in this order”, for what to do if you do have an old engine that uses too much oil between oil changes, if you are not willing or able to do a proper rebuild on the engine: 1.
Rosenfield, R. N., Stout, W. E., Giovanni, M. D., Levine, N. H., Cava, J. But the fact is, that thinking is COMPLETELY FALSE. If this aerated oil issue is bad enough, it can cause wear, damage or outright engine failure. And those older oils would need to be used up before the new oils start showing up. And I back-up everything I post with hard Engineering Test Data. But, even at that elevated temperature, it produced an impressive 124,573 psi, which still kept this much hotter and thinner oil in the FANTASTIC Wear Protection Category.
And if oil A produces twice the psi value of oil B in my testing, then oil A will also offer twice the wear protection capability of oil B, in a running engine.
The species was named in 1828 by Charles Lucien Bonaparte in honor of his friend and fellow ornithologist, William Cooper.
I have no agenda here. A dispensary will charge you around - $10,000 TO $15,000 for this type of quality yield.
Cain III, J. W., Morrison, M. L., & Bombay, H. L. (2003). [155] Males in New York usually covered more than 0.8 km (0.50 mi), sometimes up to 3 km (1.9 mi), during hunting efforts when flying away from the nest area. [164], When hunting bats, they can follow all twists and turns, and may succeed in capture in up to 90% of hunts.
The Best Coolers | Reviews by Wirecutter Smith, J. P., Hoffman, S. W., & Gessaman, J. And it provides nearly 2 1/2 times as much wear protection as the lowest ranked Joe Gibbs Break-In oil here. If you still have any doubts about how a small drain can discharge a battery, try this easy test and you will see for yourself. Its filter media end caps are unbelievably cheap “CARDBOARD”, NOT metal as is normally used in quality oil filters. And should use the viscosity recommended by the manufacturer.
If all that is not bad enough, the filter media was NOT sealed at the bottom. *not all coolers have clearance. Package: comes in 3 separated boxes with discreet packaging. They will sometimes provide links to lame Internet articles, which are often just a lab test of a single individual zinc component, showing what it did in that particular lab test. However, the only exception is for those few engines out there that may make bothersome cold start-up noise with 5W30, that can be eliminated with 10W30. This indicates that the lighter components in the oil are beginning to boil off, which changes the oil’s chemical composition for the worse. 1)Of these 12 oils, the top 10 were in the over 90,000 psi “OUTSTANDING PROTECTION CATEGORY”. Therefore, you are only looking at a single data point of a test that is not even what will end up in your engine. WARNING!!!
Most gasoline engine motor oils start with TBN around 8 or 9)Viscosity (cSt at 100*C) = 10.7 (cSt range for SAE 30 is 9.3 to 12.4) And cSt (centistokes) in general terms, represents an oil’s thickness. In addition to that, with all the other variables between dyno’s (due to different makes and models, strap tension, tire pressure, tire rubber compound, dyno cooling fan airflow, etc, etc), don’t put much stock in the amount of HP they claim you are putting to the ground either, since the numbers will be all over the place.So, at the end of the day, you have to decide for yourself if you think a Chassis Dyno session is even worth the time, cost and effort. And any oil thicker than a hot 30wt for the engine example above, would reduce that intended oil flow rate/lubrication. So, Gear Oils/Transmission Oils are NOT typically as thick as most people think they are, based on the viscosity shown on the label. Thank you very much for your research and contributions.
Everything else it does, comes AFTER that. And as you have seen by now, the cam and its intake valve closing point, is the primary factor for determining an engine’s DCR. [3] The birds found east of the Mississippi River tend to be larger on average than the birds found to the west. Some Automotive enthusiasts may think that low restriction K&N air filters only benefit Hotrods and Race Cars. Friesen, L. E., Casbourn, G., Martin, V., & Mackay, R. J.
The whole point of all my oil testing, is having the data to make an informed choice when it comes to choosing the best motor oil.
It is just one of a number of motor oil additive package components that can be used for extreme pressure anti-wear purposes. [5][62] The maximum hunting range was estimated at 5.3 km2 (2.0 sq mi) in Michigan and 2 km2 (0.77 sq mi) in Wyoming.
