One of the guys at the shop I bought my moped, told me to only buy regular gas all the time (This was back in july). He said anything else would burn at to high of a tempurture and burn out the engine. I took his word for it, and bought regular for the first 550 miles. Then after going over the service manual again and again, I noticed this:
Fuel tank and fuel: Fuel: 4l (1 gallon), reserve 0,5l (1 pint) - 98 oct. gas
Hmmm...So who do I listen to? The manual, or the guy? I wasn't sure what to get on my next fill up, so I bought the middle one (not premium, or regular).....The highest octane gas (premium) is like 93...So what should I do? Obviously, if it's not going to hurt the engine, I wanna buy the best gas possible.
