Considering what to run in my 03 V6 Toyota Highlander which is a non-sludge year engine.
With my limited oil knowledge, correct me if i am wrong but the 5w20 will have the best fuel economy and cold starts and the 10w30 will have the best thermal stability. So would a 5w30 be the best of both worlds? The engine in question has been ok'd by Toyota for 5w20 use.
