ok was out today for a little run around the lake...I started motor which started too easy IMO barely turned over and was going! I run about 2-2.5 gallon of mixed gas threw it and never noticed oil drop but then again it wouldn't need much for that little of gas ...am I good to go with straight gas as the alarm never sounded? when i turn keep the horn beeps and each light goes out one by one (checking system?) just wondering if its good to straight gas
