Which oil is better??

[oosik]

DAMN - this topic DOES get old. As long as you choose an oil that meets your tractor spec requirement - you will be OK.

More important - the frequency that you choose to change the engine oil. And beyond that - the frequency that you choose to service the entire tractor.

As for premium synthetic, I use the same: Rotella T6. A premium synthetic that is comparable to Amsoil, but costs less.

You Amsoil fanatics are always comical. It’s like a club or religion with you guys. I’ll stick with what the engineers who design the engines recommend.

I'm an engineer, use Amsoil in my go-fast car, use Deere diesel oil in my CUTs, but don't have a dog in this fight. I like data. I got this test data blog from fellow engineers at JD Horicon Works before retirement. 540 RAT too is an engineer and KNOWS his stuff. Rankings start about 1/8 of the way down. Make a link to it because it is constantly updated as new oils come out.

540 RAT - Tech Facts, NOT Myths

First you'll see that diesel oils (like motorcycle oils) don't rate as high as oils for gas engines. Diesel oil has to be engineered to provide better control of oil consumption, piston ring belt cleanliness, oil system sludging, piston top land deposits, piston deposits, valve train wear, oxidation resistance and soot accumulation. Here's the data on the oils being discussed... note Rotella conventional oil tests better than the synthetic. :<0

63) 5W30 Amsoil Series 3000 Heavy Duty Diesel Oil synthetic, API CI-4 PLUS, CF, SL, ACEA A3/B3, E2, E3, E5, E7 = 102,642 psi.

132) 15W40 Amsoil Max-Duty Signature Series Diesel Oil, API CK-4/SN, CJ-4, CI-4+, CF, ACEA E9, E7 synthetic = 87,881 psi

197) 15W40 “NEW” SHELL ROTELLA T Diesel Oil conventional, API CJ-4, CI-4 Plus, CH-4, CF-4,CF/SM = 72,022 psi

218) 5W40 SHELL ROTELLA T6 Diesel Oil, synthetic, API CJ-4, CI-4 Plus, CI-4, CH-4, SM, SL = 67,804 psi

Motor oil manufacturers use more marketing BS than any other... buyer beware. I try to buy oil that has good value and offers the best protection based on data.

I have and do run Amsoil 2 stroke oil, I mix it at 50 to 1. I like there stuff but never bought into their hype. I quit them about 3 years ago and have been using Castrol synthetic in my cars and trucks and when I run out of Amsoil diesel I will run Rotella.

I’ll stick with what the engineers who design the engines recommend. Any oil that meets their specs is good.

I run Deere oil because, as an engineer, we test product at Deere using it, the farmers around me run it in their machinery, and contractors I know run it in their entire fleets.... but I've never seen test data on it. Deere's oil 'brain trust' is at the Tech Center... never talked to them. If I ever saw test data that was underwhelming though... I'm NOT fully comfortable with OEM's oil recommendations.

Look at 540Rat's lowest ranked oil... and his comments:

254) 15W30 Yamalube, Performance Full-Synthetic with Ester, Motorcycle oil, JASO MA (Gold Bottle) = 0 psi, yes 0 psi, that is NOT a typo. This oil was tested several times, exactly the same as every other motor oil is tested on this Blog. And this oil COMPLETELY FAILED and SEIZED EVERY TIME it was tested, which resulted in a 0 psi value. No other oil has ever performed so badly when subjected to the Engineering torture testing that every oil is subjected to here. For better or worse, I can only post the test results the way they came out.
This oil was tested Spring 2019.

Keep in mind that my Engineering motor oil torture testing is designed to reach each oil’s load carrying capability limit, which is then measured, documented, and used for comparison against other motor oils. So, in order reach the load carrying capability limit of every oil, my test procedure and equipment are designed to load oils much more heavily than actual running engines are designed to do. Therefore, an actual running engine may operate acceptably with a low performing oil from my Wear Protection Ranking List, as long that engine does not load its oil beyond the load carrying capability of the oil being used.

Not every OEM has sound recommendations!

Ok, If that's what you believe.
You really should educate yourself on the different synthetics brands, how they are processed, etc,.
They aren't all created equal as you believe

Then educate us, please. English with as little technobabble as possible. We're not all petroleum engineers.
I don't feel like wading thru a bunch of Youtube videos made by people with way too much free time.

Not every OEM has sound recommendations!

Examples?

Personally, I've always believed that the middle grade of anything makes the most sense. The cheap stuff is generally cheap for a reason, but beyond a certain point you're paying extra for specs that are for 99.999% of us meaningless.

 

[kenmac]

I'll let this guy explain the difference to ya.
Hydrocracked vs PAO, ESTERS

 

[dadohead]

Examples?

Lol. "What we have here is failure to communicate"

I LISTED one for you above and gave the data source. So again:

254) 15W30 Yamalube, Performance Full-Synthetic with Ester, Motorcycle oil = 0 psi

Not cheap stuff!

Here's another

217) 5W30 Toyota Motor Oil, API SN conventional = 68,069 psi

Very poor performing; same money can easily buy >100k psi


You're right oosik... this thread IS getting old. I'm done with it.

I have and do run Amsoil 2 stroke oil, I mix it at 50 to 1. I like there stuff but never bought into their hype.

I wouldn't exactly say it's ''hype'' . the 2 cycle is pretty much proven to work for me. @ 100:1 ratio

I have a chainsaws, and trimmers that run @100:1 mix and have for years. None have locked up yet. They aren't cheap throw away saws / trimmers by any means.

I have never seen a logger use Amsoil 2 cycle oil and these people use their saws every day.

This is from a saw I rebuilt that I ran Amsoil at 100 to 1. Can I prove the Amsoil did it? No. It probably got run on straight gas but right here right now I’ll blame Amsoil.
