advance auto parts name brand oil.

What is your question?

as an avid user of valvoline conventional and synthetic oils i decided a few months ago to buy bulk oil at advance auto with thier name on it to save a few bucks.it was time to change oil this week in my personal vehicles only to find debris that looked like anti sieze on my magnetic oil drain plug on all 3 vehicles.so in other words,never buy cheap oil.stick with the good stuff like valvoline,mobil 1,pennzoil and other leading products. joel burke.
