I have a 88 acura legend that has been well taken care of. The only oil filters available in my area is the 10 dollar napa gold. So it is cheaper to go to wallmart and get the 11.88 supertech fram combo. Or the 15.88 penzoil combo. If I change at 3000 miles and do mostly highway miles any of this risky? I want to see a good 10/30w super tech analysis.
