I never hear anything about the sopus high mileage oils, pennzoil high mileage vehicle, and quaker state higher mileage engine. Is castrol and valvoline that much better when it comes to high mileage engines? Or does anyone have any experience with either.
The pennzoil I think ought to be a good oil, dont know about the quaker state with the slick 50 in it however.
And is it just me or does quaker state have too many oil lines? I was looking at their website and they have a winter oil??
