enigma-2 Posted December 25, 2017 Report Share Posted December 25, 2017 Which oil is best? Mobile One? Royal Purple? Do high zinc oils provide better protection? This article (very long, very technical) goes deep into how oil works in an engine, and more importantly, how each oil ranks again all otheres. Very eye opening. https://540ratblog.wordpress.com/2013/06/20/motor-oil-wear-test-ranking/ 3 Quote Link to comment Share on other sites More sharing options...

roots57 Posted December 26, 2017 Report Share Posted December 26, 2017 anyone know what the engine oil operating temperature is in the 2.7 EB, or any of edge powerplants? shouldn't it be slightly higher than coolant temp, maybe by 10-15 deg? under normal conditions of course.

todd92 Posted December 27, 2017 Report Share Posted December 27, 2017 That guy has way too much time on his hands. Mobil 1 5W-30 and 0W-40 both rated as INCREDIBLE according to him, they're what I've always used in my vehicles and have $12/jug rebates twice a year, making the effective cost after buying at Wal-Mart $11/jug. It's not worth expending any further mental energy thinking about motor oil. 1 Quote Link to comment Share on other sites More sharing options...
