    Hi Fellow Addicts

    I am moving to a full synthetic oil for my grubbee 66cc superratt.
    im currently running 35:1 on mineral oil. Engine has done around 600 miles, so it has run in nicely. The oil is Castrol tts 2t full synthetic.
    Please any advice on weather i can lean it out to 40:1 ?? and any other preperations i should look into. Also fuel - what octaine is best i run 98 is it nessesary or am i waisting my money?
    What are you running??

    cheers

    I think 30/35:1 is more than lean enough. Youre not going to gain much more performance. And I say 93 octane is great, how much do u pay for 98?
