Am I correct in assuming this is a car issue, not an oil issue? I have been running this oil in my Prius and changing every 5-6K miles, but am out of warranty and thinking 7500mi intervals would be nice and easy to keep track of... I am not sure I'll stick with the MC SS 5w20, but folks say it is great stuff (may come down to price at any given time vs. full syn on sale/rebate). Thanks, Doug
