Not much info on it here. I have searched and read everything i could find on this site.I have a 98 Acura TL 3.2 W/ 152k on it that is leaking at the rear main seal. How is Pennzoil High Mileage at sealing leaks? Is it as good as the Fan favorite Valvoline MaxLife? I use mostly Sopus products for engine oil and Valvoline MaxLife ATF in my transmissions. I have never used a High Mileage oil. Looking for the best product to help w/ the leak.
