The best oil to use is H1R or Yamalube, But First choice, I'd use H1R, it's got a better consistency. Second, I would use "Gear Saver" by Bel-Ray for your Transmission, it's great! On the Pre-mix, it's best to use 32:1, but some run 40:1. The higher the number ratio, the leaner it will run. Keep in mind that if you see oil dripping from your exhaust, your running your mixture too lean. Also keep an eye on your spark plug for build up caused by your engine burning too "rich". -Roger
