Re: Oil. What’s in your engine?

I'm not one to change brands, much. I have used Quaker State for years and Pennzoil for many more and have no complaints with either of them. 10w30 mostly. I tried Valvoline in one of my trucks some years back thinking I was stepping up and treating it right, not knowing the truck's history. It thanked me by blowing blue smoke within days. Proves the old adage "never change brands of engine oil". So I did the right thing and changed it right away to QS or PZ. Smoke went away.
