I posted before how my focus used half a quart in about 1500 miles on the stuff before since then it has tapered off like many of you said it would but from 10,000 -12300 I've used almost half a quart again. I do a lot of highway driving. I want to do 10000 mile drains but if it's going to use oil and I'll need to add in in between I see little benefit. When I ran vwb. I didn't burn on single drop but obviously I shouldn't run that oil 10,000 miles . What do you guys recommend?
