Has anyone ever had an engine oil lab analysis done on your synthetic oil at 100 hrs. If so, what were the results?
Also, does the atmospheric temp determine how fast the oil breaks down?
I'm curious to know if the oil really needs changing at the 100 hr. interval recommended by most mower manufacturers.
I'm not penny pinching, the cost is of no concern to me. I would just prefer to change oil only when needed. My current oil, Vanguard 15W-50 fully synthetic is at 105 hrs. and as far as appearance is concerned, it still looks new.
I intend to change oil soon and change to Amsoil 15W-50 synthetic small engine oil with 200 hr. extended oil life. Also Amsoil extended service life oil filter.
