Oil Recommendations for our engines.

This past year we have seen the Mobil 1 oil formulations change. Zinc and phosphorus levels have been removed and/or lowered. Everyday I get to tear down turbochargers and with more frequency Porsche turbo engines. I always am interested to see the component wear and in many cases parts failures.

I have come up with a few recommendations..

Mobil 1 in Canada is produced and sold as 5W50... It has the old formulations with the increase from 0W40 to 5W50 with the Porsche certification on the back label. I have customers that live in Canada and bring me down the 4.5liter jugs. It can be ordered from places like Canadian Tire and Costco.

I also recommend trying to get your hands on General Motors EOS Assembly Lubricant Part Number 1052367. Right on the label it says "provides outstanding protection against run-in wear and piston scuffing.

This product is not sold anymore officially... However it is still in many dealerships inventory. I strongly suggest that you guys go out and get this "miracle lube"

Kevin, Have you had any experience with AMSOIL 'european spec' 5W-40 ? Cheers Mark

I don't know anything about the Euro formula. But there are some good oils in Europe. I have never gone over to the Amsoil camp. It would be nice to find out who manufactures there base ester.

So let me get this straight....you are recommending Mobil 1 5W50, correct? I went to the Mobil website and could not find such a beast...they have a 5W40 (for turbo trucks) and 15W50...Also checked Costco on-line... Perhaps a link

Bill you won't find it.. Mobil does not advertise it.. You cannot buy/purchase it in the US.. I'll post some pictures shortly, and I'll scan the labels. Look up Canadian Tire.
