I'll vote for the big A Mobil ranks right up there. What problems have you seen?

We run Royal Purple in all our company vehicles. Most of them we never change the oil, just change the filter and add a quart. That's my boss's idea.

I'd like to see an OA on one of those vehicles.
Wish I could find a company like that

I've ran royal purple for the 2nd time and I can't tell a difference. But I've never had an issue with any. Just thought I'd try it

So what doesn't impress you. the fact they don't run amsoil bought from you. I use mobil delvac ,15000 km between and the oil is still clean when I change it out. 130000(215000 km) miles and all is good.

Delvac is not a full synthetic.
