I'm surprised the "High Mileage Oil" fans haven't tried this one. It is a good 75 cents to a buck cheeper (at least at the store near me) than the Castrol, Valvoline and Pennzoil high mileage offerings. I think the Havoline HM was $1.80/qt. Heck, thats only 20 cents more than the SuperTech Mileage 10w30.
Anyone here tried the Havoline HM or plan to?
