Hey there everyone. I drive a 02 honda accord 2.3L with 98,XXX miles on the odometer. I have been using M1 since I purchased the car which was 45,000 miles ago. I have been a lurker on this site for quite a while now and discovered that M1 changed it's formulation to groupIII. Well now I need an oil suggestion, the car is run hard daily, since I deliver pizzas. Which means it sees allot of short trips, high RPM's, and allot of city driving. The car usually doesn't burn any oil, but I currently have castrol GTX high mileage in the crankcase right now but it already used 1/2 a quart in 1,000 miles..
