I walk in wally world today and saw quaker state high mileage with slick 50 in it. I am real scared of that oil now. How good is that oil.

Only QS knows how good it is. FWIW, it carries no API rating. Most folks here hate Slick 50, so I suspect QS + Slick 50 will remain a mystery oil. That's fine by me.

No high mileage oil has the api starburst, but most have the little doughnut thing on the back. QSHM with slick 50 has neither. Valvoline maxlife high mileage oil seems to be very good stuff. I have used the regular dino maxlife for about 12k miles and am impressd with it.

When you go on the QS web site, the data links for the high mileage with slick 50 don't work. Maybe they don't want people to know.
