Don’t Bother Buying Premium Gas | Consumer Reports


While some cars require using premium gas, many only recommend it. Consumer Reports put regular gas in two premium-recommended cars, and checked their 0-60 time and fuel economy.

  1. This video would've been more useful if you tested regular fuel in a premium required car to see if there was a difference, but I'm guessing you didn't want to be responsible for any engine problems if there were negative long-term effects.

  2. I require 94 octane in mine due to an engine tune, but most cars do not require premium.

    94 octane petrol was $1.25/litre here in QC Canada… : /

  3. high compression engines need premium gas, and nearly all turbocharged engines need premium gas or they will knock.

  4. I tried mid-range (91 octane) gas on my very old BMW and it was significantly harder to start in March where the temperate was hoovering 0. The manual says premium gas, but it defined it as above 90 octane.

    Maybe this affects old cars more? I keep hearing this claim but the test are always done on new cars.

  5. most people think premium gas has more power, when I reality it has less. Octane (the rating that defines regular midgrade and premium gas) refers to the octet molecule, an 8 carbon chain molecule that very stable under high temperatures and will not pre-ignite like regular gas may do. But this is only if you have an engine that is designed for premium fuel. There are a few cars out there that recommend premium fuel, and can actually get more performance out of it, but that's the exception, in most cars it's just a waste of money. Unless like me you drive a car that requires premium, then you should use it, or there is a possibility you could damage your engine (in rare cases), in most cases you will just get less performance, or in my Cadillac ELR, bad gas millage.

  6. Some of them do indeed lose power though CS…you may have not test long enough for the ECU to recognize the lower octane fuel and retard the timing. One example being the Focus ST. It can take regular but it loses 30 HP vs premium because of the increased octane it can advance the time improving HP and fuel economy. It even lists the numbers in the manual from what I understand.

  7. Economy cars only require economy gasoline, high performance cars could definitely use the premium gas though

  8. Both of these family sedans had non-turbo engines, with a dual-clutch or CVT, designed for efficiency. What about more performance oriented engines? V8s?

  9. I can tell a considerable difference in performance when I don't use premium. Also they use two new cars in the test and say there's no long term reliability issues, how do you know?

  10. In my Passat tsi there is a noticeable difference using regular to premium. But it's a turbo model so…

  11. I put premium on my car because it help with the engine knocking once the car ages. my engine doesn't knock but my friend has a newer car than I do and he's knock cause he uses regular ?

  12. Impreza 2.0i non-turbo. I admit no significant gain, but I notice a difference in the time between refuel (few tank of each for real comparison). 1.5 week on regular and 2-2.5 week on premium (With shell V-power (no ethanol in it)). So bottom line, for me it pay for itself…

  13. I came to the same conclusion when I was measuring the MPG on my work truck. There is a slight difference in performance if the vehicle was rated for 87 and 91+ octane. This is because there is a slightly bigger explosion from the 91+ octane fuel producing more power. If your vehicle is only rated to do 87 octane, then there will be no difference and you might not burn all the fuel. Best to go with what the owners manual says unless you changed your vehicles compression ratio for the higher octane fuels or ethanol.

  14. If you have a performance vehicle (WRX, BRZ, etc.) you have to use premium. If you have an Accord or Camry, you are wasting your money by buying premium.

  15. Cars are so smart these days even when the manufracturer suggests a certain octane gas, if you don't give it to the engine, the computer automatically calculates the difference and compensates. No lost in HP and performance and you actually save more money since the MPG doesn't get affected at all.

  16. I wish you guys tested the 2017 Audi A4.

    From the manual: The fuel recommended for your vehicle is unleaded premium grade gasoline. Audi recommends using TOP TIER Detergent Gasoline with a minimum octane rating of 91 AKI (95 RON). Your vehicle may also be operated using unleaded regular gasoline with a minimum octane rating of 87 AKI/91 RON. However, using 87 AKI/91 RON octane fuel will slightly reduce engine performance.

    I wonder if it is okay to use regular in FL on an ongoing basis.

  17. This topic is so soft, old and boring. I can give you a punching, hot, productive and insightful one: carbon build-up in ALL direct injection engines. If you really care about consumers.

  18. I had a shit Camry and I always gave it premium gas until it crashed. It's a total hoax and from now on I'll stop buying premium the rest of my life.

  19. if you're going to do an experiment, have the same control ie. the same car. I'm sure you could have obtained two identical cars. the data is going to be different between two cars. even if the results are "identical" as you say.

  20. My mom has an 09 Ford Edge and it takes regular gas but she said that she felt that the engin started to feel laggy and it was making some weird noises. So her mechanic told her to put in premium fuel and she said it feels so different. But this is only after she has been using 87 octane for over 120, 000 kilometres.

  21. Important to make the distinction between "premium recommended" and "premium required" – could be an expensive mistake. Also, this test left a lot to be desired with no data-logging of timing pull by the ECU and even better to measure cylinder pressures to detect knock more accurately. I am disappointed with their blanket statement of "don't bother buying premium gas" without adequate testing and educating on the risks. I never comment, but this annoyed me a lot

  22. CR posted 'performance numbers' generally are a lot slower than most others, both professional and individual drivers. Just being tested by a CR driver seems to lose 1/2 second on 0-60mph. For example: exact same car driven by actual car-people at Carand Driver needs only 5.7 seconds in the same Maxima. CR must have an old grandpa driving at it took them 6.5 seconds. Maybe he left the parking brake on?

  23. Awful conclusion. Everything quoted was right, but lack of good information. Premium gas is higher octane which wont preignite with carbon deposits on old cars and high compression. Also premium gas in the long run it has additives that help to prevent and maintain clean internals such as valve seats, guides, and prevent carbon buildup. I use shell fuel rewards and save 10 cents per gallon on each fillup. It's unfair for consumer reports to request subscriptions for bad information.

  24. modern cars have low octane fuel maps and it takes time for the ECM/PCM to switch to more aggressive ignition advances after using low octane maps. you need to run at least a couple tanks of premium through it to ensure it has switched to the aggressive ignition maps. Also if you buy a premium gas without ethanol you're already ahead, pure gas has about 30% higher energy content then ethanol which translates to greater power and fuel economy, ignition advance not included.

  25. Premium has more cleaning additives so it may be worthwhile to throw it in every so often even if your car runs on regular. I'd also stick with the Top Tier gas stations. Some say this is smoke and mirrors, but why take a chance? But a few trips elsewhere won't cause any problems if prices are a lot cheaper.
