Understand that this is just 2 cents of an opinion..

It takes up to 10 gallons of gas to break in a g62...before you should go to synthetic oil....It will let you know when it's ready..

Any good two stroke natural oil for air cooled engines mixed at 32 to 1...

Nothing made for boat motors or anything for water cooled 2 stroke engines should be used..

If you have avability to Penzoil 2 stroke oil for 'air' cooled engines it is fine...Wally World is my supply for it...
The reason for this is to wear in the cylinder...
Their will be more black gunk come out of the exaust than you can shake a stick at....(don't worry it gets lighter as it goes on...)
