Good stuff for UC. Either hi-teck, or trailing edge teck. If you use RC fuel you must add castor to it to bring up oil content. I have used Byron fuel with added castor and it worked fine. Most fuel sold today has decent quality but low on oil for our use. I use rough measurement of 1.3 oz. to a gallon will increase oil 1%. Most RC fuel is 17% oil mostly syns. So if you use 7 oz. of castor you will get app. 22% oil which is good for modern engines . 10-13 oz. will be good for most good plain bearing older engines. If running McCoy RH or Fox add a little more. Most hobby shops sell Sig castor oil. Comes in pts./qts./ gallon.
