Engine oil PENNZOIL or Lucas

That is my personal favorite so far. Use or burn less than anything else I have tried, and I swear the engine sounds quieter. Previously used Castrol, Amsoil, Mobil 1.

I use Lucas oil in my motor oil for 1990 VW 1.6L Jetta diesel. I started using Lucas Oil because a relative of mine has been driving a large semi for almost 30 years, and he, like many in the trucking industry, swear by Lucas Oil. Judging by the parts per million of metal present in my motor oil, my motor oil with 1 cup of Lucas Oil, was wearing pretty well.

I just picked up some Penzoil synthetic 5w-40 today and right on the front of the bottle it says "Meets BMW and Mercedes requirements" a little search on back label listed all the specs and all VW specs listed above are on the back of the bottle.
