Engine oil Shell or OEM Volkswagen

Ran t4 10w30 in my 95 Cherokee for the whole time I had it and it loved in. Never ran better

mobil 1 is trash. i go with castrol5w40 or motul 5w40 or rotella diesel 5w40

I ran diesel oil in my '94 yukon for the entirety of it's 260k miles. My dad always said the same. The zinc was better for it. When I got rid of it, it was still running fine and driving fine.

I’ve been using rottela t 15w-40 in my 70 Camaro for this reason.

I use Rotella in old VW Bug. Seems to work well but i put very few miles on the car.

I run Rotella in my 49 flathead and in my 91 civic.

As long as you don't have a catalytic converter on it Diesel oil with Zinc is the best

I run Rotella in my E24 at the advice of people on the BMW forums.

So I took his advice and did the Rotella T-4 and MMO in my 71 LeSabre 350. Added a little to the gas, too. I run 93 octane gas. Engine is stock and original, about 90k miles. It's running so smooth now. It was an immediate, noticeable difference.

G60 Carat said: Speaking of Rotella, Here's a personal observation of mine. My beater Saturn 1.9 has a lifter tick (not fixing it, don't care), so I just put in Rotella T, and it quiets it up a bunch! But last oil change I just used the 20w50 I had on the shelf for the VW, since it's in pieces anyways. Despite the heavier oil, the lifter tick is louder with 20w50 that it was with 15w40 Diesel oil.
