AA has QS 5W-20 syn. on close out for .95 cents per qt. I was thinking about a 50/50 blend of 10W-40 QS conventional and 5W-20 syn. for a avg. of 7.5w30
Or a blend of 10W-30 QS conventional and 5W-20 syn. for a avg. of 5W-27.
It is to be used in a 01 Yukon 5.7 engine with 84,000 miles.
What is the thinking good or bad on these blends?
