16%-18% oil is fine for backyaqrd bashing. The right brand fuel makes all the difference. I have use wildcat 18% oil no problems. engine runs cooler than Omega fuel. Less oil is for racing. You will spend more time rebuilding with less oil.
Less oil is for better engine protection because of the castor oil and lower engine temps. How would the backyard basher not want that? Actually you will spend more tiem rebuilding with 18% synthetic oil, especially Blue Thunder which has alot of synthetic oil and everybodies engines runs like crap with that fuel!
