Ok 2 questions.



1: I hear it's not good to mix synthetic and Dino oil. Well, is premix Dino? And will it be bad to use premix while running synth in the block?



2: Mobil 1 has added some new **** to their synthetic oil. Anyone know anything about it?

Sorry, one more question... I've seen several different shades and colors of premix, but they are all labeled the same... Are they?

pre mix is dyno, but it doesn't mix with the oil in the block.

there was something about mobil suing another oil mfr. i didn't read it but i gather that the label "full synthetic" doesn't mean it is.

i heard that mobil 1 has a additive in the synthetic that is not good for the apex seals.. anyone else heard of this..... i use red line and it seems fine...

Tri-Point and Pettit racing both use Red Line synthetic.

Pettit sells a premix (Protek-R) which is a synthetic 2 stroke.

Racing Beat uses Royal Purple and used to use Amsoil.

There are alot of guys that use Mobil1 since it burns clean.

I use Royal Purple since the company Races rotary and Racing Beat claims proven increased HP.
