the 5/20 is more about emissions, fuel mileage, etc...
why do you think some Honda's run a 0 weight... its not because of tight clearances.
as far as M1 is concerned, i also used to swear by the stuff, but its not the same formula as it used to be... when Exxon bought out Mobil, the oil changed from what i understand.
If you do some research, M1 was having some high levels of start-up wear in testing.
Pennzoil Platinum was the best off-the-shelf oil there was, until they released their Ultra line. Which is why i use it in a pinch.
Amsoil is good stuff, but only some of it... and im not all that well spoken about their stuff. Usually though, its very good for extended drain intervals, but for normal intervals, Red Line still smashes it.
Royal Purple is expensive piss, same base stocks as M1 and other normal synthetics.
Nick likes diesel oil because it has high levels of cleansing agents compared to oil geared towards gas engines. I dont recall why, weather it be extended drain intervals on diesels, or their higher carbon output... but its true. Diesel oil def has more cleansing properties than most oils.
