Is oil. oil?

[Ortimber]

I use Rotella T6 in everything except my daughters Corolla. I stay with the recommended 0-20 since it’s still under warranty.

Yes, you can use diesel engine oils in gasoline engines. No problem whatsoever.

Only 1 person speeks about the C (combustion) spec and the S (spark) spec off oil ! That is what you have to look at ! Early oils can be a CB....CC ....CD spec . The furter in the alphbet the better the oil ae a CI oil will fulfil all the specs off all oil from the start to the CI but not the CG ae that will be better than the CF.
The same can be said for the S (spark) spec oil .
The W(wight) has all to do about the ambient temp !
I hope there will be someone out there to correct me
Thanks.

I got my first diesel truck in 1993 and posed that same question to the dealer. He said to not use gasoline engine oil in diesels because it will wash the cylinders clean and will score quite quick,. True or not but that convinced me to keep them separate. Diesel oil can be used in gas engines though except new cars use very thin oil now so 15/40 Rotella T will be to thick in many of them.

That is our choice since it is good for every engine we own and none are under warranty and have never learned about a better motor oil choice.

Now for then next step
You get a singlegrade oul that is a 30....40 and then you get a multi-grade oil that is like 10 w 40.
Then you get a multi-functual oil that you can use in the engine aswell the gearbox and your hydraulic sisteem.
Make sure and get the correct oil for you location !

A 10w30 oil is probably what plain old 30w oil was years ago before the change to rating it multigrade.

And just how does a person arbitrarily arrive at that conclusion? :confused3:

whoa 1st i've heard, wonder why? use it in my 3 vehicles....at least they should have a disclaimer on it. so would it void a warranty on a new vehicle? (all mine are 20+ yrs old) & still going to run it tho
so why would shell, knowing their statement would reduce potential sales, say that?

I have over 20 things here with engines. All of them except my 2018 Cheverolet which specifies 0W20 get the 5w40 diesel oil.

I had an '09 Ram Hemi 8-4-8 and the owners manual said that if you use higher than 5W-20 oils in the engine that function may not work. Also said the oil pump in that engine was designed for the light oil........for a guy that has believed in heavy oil all my motoring life, that was truly a shocker and took some getting used to.

But I did and no problems.
