Might want to think about using Mobil 1 Annual Protection 20k mile oil

[Dr GP]

Not saying you should actually keep it in for 20K miles but 10 K would not seem unreasonable.

Check out these 2 videos that show what goes into the development and testing of the product.

Interesting

Double the price of standard Mobil One synthetic, so it's more of a convenience factor than big savings. Yes, interesting.

Not saying it may not be superb oil, but until someone actually uses it and gets an oil test done, it's still just marketing claims. I think any long use oil is still going to get contaminated from combustion by products-- I don't care if its made out of extraterrestrial unobtanium
