I read ethos FR website today.
Adding 1 oz. to OIL at next oilchange is part of requirement to qualify for
I have to wonder about good old Marvel Mystery Oil which some mechanics, esp. diesel mechanics, swear by.
The pitch Ethos makes is that "esters" help vaporization by breaking up "clumps of molecules"
and, it's 100% bioderadable . . .
As with all additives, if the stuff is so good, why is it not already included in fuel/oil? You'd think with oil and fuel companies doing everything possible to improve their products, any magic bullet would be already added.
