Man I learned alot here tonight. Question.... "Dino Oil" is just regular old oil right?
I heard also that once you go to Synthetic you cant go back to "Dino".... is this a myth also?
Also, Everybody knows Crunchy kicks Creamy in the bottom of the Jar everytime.

 

dirty comment about peanut butter aside

my old jimmy (still lol saying that) had mobil1 everyday of it's life. the motor is DEAD SILENT. i didn't realize it was that good, i'm not skipping a minor tick, nothing, the only noise that engine makes is that air sucking sound when you hit the gas. that sold me on mobil1 synth.

my 3.4 grand am got a little more quiet, especially on startup after a change to it, and the ancient s10 was just a beater, it was loud, and didn't really change anything with it.

our new sorento is 5-20, and it's new, so it's only had the mobil1 synth in it, but at 6K mile (100 miles a day highway, i'm not doing 3K changes) intervals, it looks like it could be poured right back into the top end. it is unreal.
btw, until the jimmy i was a devout castrol gtx guy
