Hi guys, I'm back with another stupid question, however was wondering whether or not using old fuel in a baja will ruin the engine or not. The HPI instruction manual says fuel over a month old could potentially damage the carb and engine however that seems a bit ridiculous to me so I was seeking the help of you guys. I've got some decently old fuel in the garage (3 years old) and I was wondering whether it would be alright to run. WHen it was new it was a great quality mix of 98 octane and valvoline fully synthetic 2 stroke racing oil. Thanks
