You should use a minimum of 91 octane in street bikes, ATV's or Dirt bikes
It is recommened that you use premium only but you can use any fuel that you want... I wouldn't do anything with ethanol
Upper-end cars use Premium fuel
Premium Fuel 91 octane.
You need 91 Octane, which you can use 93 octane and 89 octane mix. which is Premium and Mid grade fuel.
It is highly recommended that you DO NOT use regular gas in ANY Mercedes. They were all built to run on premium and you can cause serious damage to your engine if you don't. In fact, I've been told that the "premium" fuel in the US is garbage compared the the premium fuel in Germany. So, don't use regular if you like your car.
Premium fuel
Depends on which Model/Year Matrix you own. Some require the use of premium fuel and some do not. It yours requires the use of premium fuel then by all means use it. If yours only recommends regular then using premium fuel will provide no benefit whatsoever and is a total waste of money. Your owners manual will tell you exactly what to use.
Any grade is fine. It doesn't require premium or mid grade.
only use premium fuel in European cars,
My answer is YES! if you do not use premium fuel you will see a decrease in fuel milaege, lack of power, and carbon build up. I work at a vw dealership, and I've seen more than once where people come in complaining about their engines acting up. well it turns out that they had carbon buildup and they did NOT use premium fuel. I own a jetta myself and I would not use anything but premium. hope this helps
i use 76 premium
Premium (93)
