It's all-too-tempting to order the cheapest grade when filling up your tank, especially with the recent hike in gas prices. But do you even know what kind of gas your car requires -- and what those numbers near the pump actually mean? Automotive.com is here to help!

What does a higher octane rating actually do to your car? And what happens when you fill regular gas into a ride that requires higher-octane fuel? Those questions and more are answered in the video below. Don't be a dummy when it comes to your wheels. Go ahead: Understand octane.

    Doh! They canceled autoshop at my school when budgets tightened. This video helped me understand octane a whole lot better.

    That sticker on the pumps used to guarantee us we were getting that grade of fuel. Now the only guarantee we have is somebody is getting paid to put stickers on.

    I have a small p/u and it runs best on regular unleaded.

    When we used leaded gas, which they added lead. But when we started using unleaded you think it would have been cheaper because no lead, but No, gas keep going up. But they keep adding taxes on it to pay for other things.

    Since my SUV has a high-compression engine I use premium gasoline.

    Bottom line is the higher the octane number, the more compression the fuel can withstand before detonating. In broad terms, fuels with a higher octane rating are used in high-compression engines that have higher performance. The use of gasoline with less octane numbers may lead to the problem of engine knocking.
    And that's not good for the engine.

    Owners manual requires premium.

    This poll doesn't take into account that some people own multiple cars. I put Regular Unleaded in my Jeep Rubicon and Lexus SUV, and I put Premium unleaded in my Nissan GT-R. Since I wasn't given the ability to select "other" or a combination, I decided to select Diesel to skew the results because I found the lack of options annoying.....

    High octane translates to lots of additives, and high price.

    If your engine doesn't ping, or show other signs of poor combustion, just use the cheapest fuel. If it pings, smokes, runs hot, or has any other problems that indicate poor combustion, then try a few tanks of higher octane. You WILL NOT gain any energy from the gasoline with the additives - you actually LOSE a very tiny amount of energy, while increasing costs dramatically.

    Similarly, a lot of tests have been done on 100% gasoline, compared to 10% ethanol. The mileage is very close, with the 100% gasoline maybe getting a fraction of a mile better mileage in some cases.

    Overall - the cheapest fuel at the pump is the best, most economical choice. By "economical" I don't mean instant savings, but long term driving. Most cars are wrecked long before the engines wear out or burn up anyway - don't waste your money on specialized expensive gas.

    My car requires it but I don't think it burns slower. The manufacturer told me that it will eventually affect the performance of the car. They never said that it will damage the engine either. Are these claims legit?

    i disagree with the video, it said the internal combustion engine squeezes fuel until it explodes. this is false, it does squeeze it but then sends a spark to the spark plug that causes the fuel/air mixture to explode. A diesel on the other hand, does compress the fuel/air mixture till it explodes.

    Check your owners manual for the recommended minimum octane rating for your car.

    I didn't put what kind of gas I use in all my cars, if we do they will look at this poll and just target that price and make it higher.
    I wouldn't put it pass them at all !!!

    All gasoline is unleaded, so why do they still define just the lowest grade as "unleaded"?

    Except I think unleaded is 97 here. And yes, I know my car runs on the cheapest one and does not require a better one. I would happily buy Opal fuel if it was available, but that's more of a rural thing.

    My question is ?? Why do we need this other crap (ethetnal) in our fuel? It cuts your gas milage down, It puts you on the road longer, You burn more fuel. SO where is the savings?? BUT st someone sure made a hell of a lot of $$$$$$$$$$$$$$$

    There is a noticeable difference in my audi when I fill with the cheap stuff..like 2.5 miles to the gallon difference and it is sluggish..
    I actually only buy 93 for my audi but throw 87 in my 250k mile Volvo..

    Dont need the other grades. One grade is good enough. Stop paying half the price of gas in federal and state taxes.

    I buy Plus because it is usually 5 cents a gallon cheaper than unleaded. If unleaded if 5 cents cheaper, I buy that. Only very rarely are they the same price.

    it actually doesnt mater much about the octane unless you have a high compression car (usually older)...its the ethanol that is hazardous to you engine...no matter what octane you put in it, today's engines would last half again as long if the ethanol was removed.
    even high performance car makers (Audi, BMW, Volvo) will void your warranty if you put ethanol in them...and I think they are more educated on the subject than the EPA

    Here in the UK most cars run on unleaded gasoline (which we call petrol) and diesel. Many cars use Liquid Petroleum Gas or LPG which costs little over half of what gasoline and diesel costs per liter. There are 4.55 liters in an Imperial (UK) gallon as opposed to 3.8 in a US gallon. In addition there are now several thousand electrically powered cars on UK roads but there is a Catch 22 situation with them. Service stations are not going to start providing charging facilities for electric cars until plenty of people own them and people are not going to by them until there are plenty of charging facilities so the government has stepped in to encourage the ownership of such cars.
    I once experimented with home-made bio-diesel with success and my next car will be a diesel one so I can use bio-diesel. Until a few years ago the government required people to declare duty on home-made biofuel even if people made it for their own use but in 2007 scrapped that requirement for amount of up to 2,500 liters. Duty albiet at a reduced rate is charged on bio-fuel that is sold.
