I want to list "universal amounts" of these chemicals on a "side-by-side" list. I'll take the universals from one of the Blackstone reports posted here.

Also, since the manufacturer's suggested OCI is 7,500 AND the recommended oil is conventional in most cases, I think I'll go to 9,000 or 10,000 miles.

BUT since Winter is coming I think I'll stick with 7,500 just to see if my Winter driving (shorter trips etc.) increases the baddies in the oil.

What does anyone think about my "plan"?
