"Good afternoon. My name is Tom Brintzenhofe, certified master mechanic, from Reading, Pennsylvania, and today, we're going to talk about how to purchase the correct gasoline. Each individual vehicle that is made out there, serves different purposes. You have your SUVs, your sports sedans. You've got your sports cars like your vettes, your Dodge Vipers. You have your little economy cars, your little metros, little Focuses. Every engine configuration is a little different, modified, and built set certain ways, and they're all basically built to run on a certain octane of fuel. Now, you take your typical Corvette, and you put an 87 octane in it, you're basically going to void your warranty, because it's just going to run horrible, and you're going to end up screwing the motor up. The only way to fully know, without any doubt, what fuel goes in your engine, is either one, call your local dealership, or two, grab your owners manual. There's always a section in your owners manual, as to what fuel, what octane rating you should use. Now, this particular Mazda MPV, I've already gone ahead, and looked this up for you. On Section 4-2, it says regular unleaded fuel, 87 octane, minimum rating, so basically, you can put just about any fuel in here. You can put a higher rated fuel in this vehicle. It may run a little better, it will get you a little better gas mileage, but 87 will do it. I hope that includes any questions you might have on fuel."
