just curious to what oil all of you guys use? today i was at advance auto and theirs a guy there that has a fixed up red cherokee the old renix style and he told me he runs Rotella 10w-30 because its thicker and its like diesal oil it has something in it, He said he has been running it for 18 yrs

 

i was thinking of giving it a go

 

I see many recommend Rotella, I believe they've said it has a Zinc additive in it. The actual science on what that is helping I haven't seen.

10w30 is what the engine is rated for standard temperatures. If temperature will be staying below 60F then 5w30.

Any oil of the same Viscosity should be the same "thickness", the higher you go in numbers the "thicker" it will get.

Some will use heavier weight oil to compensate for wear and tear, increased clearances, leaky seals, etc. Again, this is mostly conjecture and is up to you to experiment and decide on.

Beyond that, as far as which brand/type, again that is mostly personal choice and experience. Everyone is going to swear by a different product or bash something that didn't work out for them but could work great for you.

 

5w-30 Royal Purple

 

iv always used Penzoil 10w-30 id like to try Rotella triple protection

 

thin eh lol, does that royal purple actually perform better?

 

Shell rotella in everything I own.

 

I run a 87 and been running Rotella and there is a lot of science on why it is better. We get a thread like this all the time.

Run a search for Rotella and i am sure u will see many of our resident scientists backing this brand.

 

really now?! im thinking of changing oil today and putting rotella in

 

5/30 castrol (or any decent brand) There doesn't seem to be much discussion about zinc over here in the UK.The lower first number means it gets an easier time during start up/cold running. In theory.

I never stray from the manufacturers recommendation for the second number since they know what tolerances their engine is built to.

 

ive been using castrol gtx conventional 10-30. in my wrx i run the same i think except synthetic. alot of people do use the rotella because of the zinc additive. i would never use high mileage oil in my vehicles because it has an additive to make the seals swell to stop oil leaks, i like knowing if i have a leak so i can fix it. with cherokees 10-30 conventional will be fine and get great mileage out of it

 

Yup. I run T6 full syn. I'll post the oil analysis when I get it done in another 3k miles.

 

What kind of rotella?

 

Mobil 1, cause i work for them.

 

Why does your oil suck so hard?
