Run lawn boy or Pennzoil. They are both good oils. There will always be someone that tells you to run one or the other. One is better than the other. The fact of the matter is mix one of them at 32 to 1 and go fly it with a 22X8 prop and enjoy. All this talk of heat cycling and special break in procedures is a bunch of over paranoid bull crap. Do your normal flights and then, let it sit for a minute. don't thrash on the motor until you get a few gallons threw it. I didn't do anything fancy when I broke in my motor, and when I started I was getting 6850rpms on a 22X8
Zoar. After about 4 gallons it was like a flip of a switch. It went from what I thought was running normal to ripping the prop. I landed to check what the heck changed. I check the needles. I then checked the RPM's, 7650RPM's. I was shocked!! I had to check it agian just to be sure. It was correct, 7650. This motor runs perfect and starts very easy. You guys will love it.

Also the guys are right. Throw that stock plug in the trash. For one thing it fits loosely in the head for another it doesn't last. I switch to the NGK-CM6. Trust me it makes a difference.
