Engine oil Shell or FUCHS

Rotella T6 0W40.

Phattbotti tuning has done oil sample tests in multiple oils and he says Rotella T6 5w-40 is the best bang for the buck.

I use Castrol for the Nexon and Punch. The Safari uses Shell. Shell and Castrol are by far the best I've come across. Shell is much much better for the cold weather, by what I've observed.

My 96 xj I would put in 5 quarts of rotella 15-40 and a quart of Lucas oil stabilizer purred like a kitten

Our Blueprint crate 383 stroker calls for Rotella as an acceptable oil for daily use. Cheaper, too.

Run Rotella in my 80’s and 90’s BMW’s often. They seem to like it, and sometimes it’s cheap at Walmart.

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 posted my UOAs on TDIClub and BITOG. The factory fill was additive depleted at 5400 miles. The Fuchs 507.00 in the next fill was good for 7-7500 miles. It might have gone longer, but I changed it out in advance of a long trip. Bottom line is that preliminary evidence is that the 507 oils are inadequate for extended OCIs in the 3.0L motor.
