pretty much anything else i think....i have only heard ppl talk about smell w Rotella
reason i say i would rather stick with a non synthetic is because i have always been told that if a motor hasnt been run on synthetic from practically day 1 then not to switch. so with 160K i would think switching might not be too good on the seals.why not synthetic with 160K?????????
hahahasmelling and sniffing motor oil is like smelling and sniffing a woman's butt.
:confused013:doesn't tell you a thing about quality but makes some men feel better:spank:
