Hey everyone, my owners manual says to use 5w20 motor oil for my 1996 Mustang GT 4.6L v8 but then i read this http://www.smartsynthetics.com/articles/5w20oil.htm what do yall use? does it matter if you have mods? what weight do you use?
but whats the difference? i mean does it really do anything differently? isnt the less weight it is, the better because less mass rotation or something, i read it somewhere. like isnt 0w30 like the recommenced best for performance and gas efficiency? im trying to learn about oil here lol
It would have voided my warranty on my 02 F150 if I used anything but 5-20 I was told, at least it would be a big hassle...I got stuck once & did try some 10-30 but boy did my lifters clatter on startups in the mornings! I found some 5-20 & changed back after only 300 miles & the clatter went away!
