Engine oil Shell or OEM Honda

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 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've used a number of different oils in my XS400 over the past couple years, can't say I've noticed much of a difference other than when I used a 15W40 the engine was a lot noisier, going back to 20W50 and the engine quieted down a lot.
