Just follow the manual. 90+ octane gasoline and quality chainsaw oil mixed at 50:1.

For me that usually means 93 octane & Stihl Ultra.

....

what type of engine are you "breaking in"?....... most engines dont require a break in fuel mix..... but if you want you can use marvel mystery oil in the first tank full.....that be fine. mix it right-- the ratios are right on the container....you should add it to your oil at every oil change too. this stuff works great. it'll keep that engine clean inside... and it will work better longer without that sludge and crap building up....

personally i always mix 45-1 with 93 octane,, then run it like you stole it

8 years ago I bought a new MS440 I have ran 91 octane and Stihl dino @ 50:1. Pulled a comp check the other day it still blows 150 psi. I have no idea how many cords or hours but it has been used.

No need for "special break in fuel' Just tone rich on the H jet say 13500 factory recommendation tune to 12500 or so for the first few tanks and run it.

No. Use the same mix you'll always run in it.

I agree with brad. If you keep with the same fuel and same oil all the time you remove some parts of trouble shooting and forseen issues. You can pick up on little things quicker is you dont add new things to the list.
But to each his own.
