    Just my opinion. But I would use the dino oil for break-in. Synthetic afterwards for the long term. Reason? Parts need to wear in and synthetic is a little too good for that.

    I've got a lot of miles on mine using Echo weed whacker oil at 50:1* ---- same as my weed whacker.

    *(Your results may vary.)

    What oil should I use inmy 79cc predator ? I used Walnutz brand 10-40 at first, but now its got 100 miles for break in, and I'm wondering if I can free up some power by using like 5 30 synthetic?
