  1. I would prefer ethanol free if possible ethanol leaves a gummy destructive deposit like a broken down fructose "syruppy"deposit.

  2. Where in the heck is the manual that tells which gas to use located in our cars??
    I've been looking for that book for ages lol

  3. It's simple: These higher grades are for cars who need it. There are quite a few cars out there who need it. Of course the oil companies use some form of marketing to upsell their higher grade fuels, otherwise it would be too expensive to have multiple grades of fuel at every pump station. If you would like to make premium gas have an impact on your regular car, get a OBD tune for it.

  4. A common misconception is that premium is more "powerful" gas than regular. Octane is simply a measure of a fuel's resistance to preignition. In higher performing engines running at higher compression, there is a risk of preignition and knock with lower octane fuel which is detrimental to your engine's performance. For the vast majority of cars, of course there is no benefit to premium because they aren't running in a manner that requires it and there is no magical boost in power from 91 octane.
    From personal experience driving both a Vovlo S40 T5 and a Subaru WRX, both with turbocharged and high compression engines, they do not like regular gas at all. It has a noticeable and detrimental effect on performance and fuel economy. The owners manuals both specify that 91 minimum is required. The STI model of the WRX actually asks for 93+ octane where available and 91 will do worst-case scenario.

  5. Premium is better for your car my car never needed fuel pumps injectors and it burns slower 87 goes out fast

  6. I've tried running all tests of gas in my car and found it runs ok on mid grade spits and sputters with low test and high test it runs great, best advise here is run a tank or two of each grade of fuel in your car and see for yourself which is better for you, the tests ran here is totally and only a result for that car and that car only. You can take two identical cars and get a noticeable difference between the cars every time!

  7. I’ve owned a 2016 accord 4 cylinder since brand new and since brand new it always had a very slight stumble sitting at idle, after switching to premium it took about 3 tank fulls and the stumble completely went away and hasn’t been back since using premium

  8. My stepfather used to add a quart of oil to the gas tank especially when we went out of town now I don't know if it's because at that time Vehicles burned regular gas and you could do that but never bother his vehicle

  9. Okay I understand that this is for the simply car and driver that has a normal car. However if your owners manual suggests premium just use premium. I’ll use my car for example in my owners manual it suggest 91 because it performs better it makes the full amount of horsepower as it’s rated. I could use middle grade but it would make less horsepower. It all depends on your vehicle. Not all engines run the same, they perform and act different on 91 or 87. Most cars runs fine on 87. But for more performance or higher compression vehicles use what is recommended. Cars that require 91 will knock more, have a shorter life, and perform worse on 87. But hey who am I right. You won’t listen to a random comment from a random person. So do what you want.

  13. Anyone with a 2011 Nissan Murano ever try Premium Fuel? And does that actually make a difference?? 🤨🤨 pls help!! Ty in advance

  14. If the fuel has ETHANOL added to it, it is fine in your car. BUT, it will ROT (over time) the hoses and rubber fittings in your small engines (weed eater, lawn mower, boat motor, dirt bike, snowmobile, etc) and will also varnish up your carburetor in those same small engines because they sit for extended periods and the actual gasoline in the fuel system evaporates leaving the ethanol behind to bung up the carb….I know Sunoco Premium has NO ethanol and is what you should use in your small engines…..In your car, run whatever…Pay more attention to your regular oil changes and tire pressure and air filter.

  15. Bottom line is every vehicle has an owners manual and that owners manual will tell you what the recommended fuel grade needs to be used in your vehicle. In my older vehicles it would make a difference on what fuel grade you ran and I would hear a knock from the valve train if I used to low of a fuel grade. My 2018 Ram 2500 and all other newer vehicles will compensate for the fuel you run in them. I drive 100 miles a day for work and I have tried all three fuel grades in my area and there was no difference in my gas mileage or fuel burn. READ YOUR OWNWRS MANUAL AND RUN THE RECOMMENDED FUEL IT CALLS FOR.

  16. What motor in the car? Either way, the Turbo cruze is also tuned for 87 octane. Use what your manual says to use. If you have a high compression engine, and it says 91-94, use it. The higher the number the MORE resistant to combustion it is, and in high compression motors it prevents pre-ignition/knocking. So do what the manual says.

  17. I don't believe the average gas station worker is trying to mislead anybody. It's a top down misleading myth. The people that are scamming are doing it by simply not informing people of the differences. Corporations are making billions of dollars by labeling things as premium by labeling things such as premium, or organic etc. 8 out of 10 times this is the case according to the American Bar Association center for consumer awareness

  18. its a shame they didn't just explain what octane ratings mean and how some cars require it based on the compression ratio… instead this was a bunch of balogna

  19. Newer engines have the ability to take advantage of higher compression ratios with higher octane gas. My Chevy Volt gets higher mpg on premium, and even better without methanol, as tested on road trips. The mpg improvement is about enough to cover the price difference. The car will run on regular, but only by retarding the timing using anti-knock sensors. Aside from not mentioning that, your dyno power test is completely bogus. Think about it. Maintaining a set speed at a set load condition with the same car will take the same amount of power and torque, regardless of the fuel. You didn't bother to monitor the fuel flow even though it's in the same CAS/ODBII data stream, probably because it didn't fit with your hypothesis. Any true expert would have pointed that out, but you ran with the junk science anyway. It's about the same as asking the guy who pumps gas to evaluate octane efficiency for your car, then taking that as the official company line. Please redo the segment with a credible analysis.

  20. I guess these people don't believe in hooking up a live monitor to the computer to see the knock sensors but they also forgot to mention about advance and retard timing when you use a lower grade fuel your engine have a tendency to retard the timing and if you use a higher grade fuel it will advance but who am I I'm not a blogger I'm just a car person and a mechanic who knows how to use a Dino🤷🏾‍♂️

  21. Lmfaoo wait the best gas at these pomp is 91 octane, meanwhile in western Europe the BASE stuff is 95, then we got the 98 (a bit more pricy but still not "premium" and then premium which is 98 + additives n better fuel overall

  22. PREMIUM FUEL IS A Petroleum Industry Ripoff!!… …Your better off getting a
    99 cent bottle of gas treatment and adding it to regular unleaded!!

  23. The oil companies representative is a liar here. A persons who has no dignity by lying through his teeth. Unfortunately, all the big companies in the U. S. forced their employees to lie. There are no exception, the only thing is who can tell a bigger lie. It’s a sad country.

  24. My Mustang does have better performance with the higher-end gas. I can tell because there's a slant where I turn around, with the lower-end gas my car will reverse downhill even when it's in drive, with the higher-end gas my car will not reverse downhill when the car is in drive. It also has more power. It's a noticeable difference.

  25. I once put regular in a rented Benz, and it sounded like somebody put rocks in a blender. Some cars are tuned for it, but there's absolutely no reason to use it in a car that isn't.

  26. um…. something doesn't seem right. If the computer is able to compensate for a higher octane fuel to achieve the same power it should be using less!

    In my personal experience I got marginally better mileage in winter months…. when it was -35 degrees C.

  27. The higher octane doesn't actually clean your engine or make your car better. The higher octane gas is for high performance cars such as chargers or challengers. They need the higher octane for their engine because of the high performance

  28. This is so misleading. Not every car has a knock sensor. They wanted you to believe what they were trying to market. You need to know your car and simply follow your car's engineer's recommendation for the performance of your vehicle. Forget all these misleading videos that try to have you look at things the way they want you to.

  29. My 2.5 altima runs smoother on 91 octane and up..the 87 makes it vibrate on idle and pings when i step on it hard

  30. it depends what car you own actually. check what gas your car needs, my 2008 bmw 328i runs premium cause of the compression it need to detonate its important you research what fuel your car needs, it will save lots of money in the long run. trust me i hate spending more than 20 bucks for half a tank but i need to take care of my car.

  31. Use premium fuel in lawnmower and other smaller engines less ethanol so less likely to cause issues with starting come spring. Yogawoman is not doing yoga she is not wearing lulu pants.

    Higher grade gas won’t give you higher mpg it depends on weather plus driving conditions how well the car is maintained weight in the car etc etc

  32. Brings in a N/A Corvette owner to cover the preformance car aspect… But it's so wrong about high quality fuel on built motors, especially boosted motors…

  33. My 04 Cavalier gets better performance with 89 and 93. 87 octane fuel in my car causes poor performance on hills on which I am surrounded by. The extra money per gallon is worth it for my car so it's up to how your car performs on what fuel.

  34. When you get a car the manual tells you the kind of gas you get. It depends on the engine. If you put wrong type of gas it can damage it.

  35. So he's kind of contradicting what he's saying. First he says there is no point filling up with premium unleaded, but track days he will? what's the logic behind that?

  36. The gas industry is screwing the American public why not only for the high-octane but because every one of the gas stations have different prices if you go to Florida and go through state Route 40 in Ocalla every gas station have different prices that one is the same they’re all up high or low who do you trust maybe you ought to look at that price gal Ching all over the state of Florida

  37. Now I’m confused, I have an Acura, the manufacturer says it is requirable to use Premium Fuel, I’ve been putting Premium since I got it and I never put Regular on it, am I just wasting like a couple of bucks more for no reason or do I really need to believe what i just watch. It all seemed strange since they’re testing this things on a pretty base model car.

  38. My 1991 Audi required at least 91. I use Chevron 94. Because I don’t want corn alcohol in it. Over three hundred thousand kilometres and still runs good.

  39. READ YOUR OWNER’S MANUAL, THE ONLY REASON THEY ARE NOT WORKING IS BECAUSE IT MIGHT NOT BE RECOMMENDED BY THE MANUFACTURER OF YOUR CAR!
    Edit: This video is very misleading, premium is needed for sports cars and supercars, the only reason the Chevrolet Cruze didn’t work was because the car wasn’t recommended for the gas

  40. I would like to see this test redone on a engine that actually requires premium fuel. No sense running that on a chev cruze..87 is all you need. Another test I woulds love to see is on a engine that is premium recommended. I have a 2017 with a 6.2l which is premium recommended. I usually just run regular and had 0 problems.. no engine knock or anything like that. But the seeds of doubt are there in the long term. Gas is expensive and I do run a few tanks of the good stuff through when i can find it under $1.30. But..I always wonder long term..with the higher compression ratio of the 6.2 will I cause damage or build up long term. Any opinions?

  41. I remember a few months ago thinking, while pumping gas, I bet it’s all the same. Best way to boost octane is to do it yourself.

  42. 87 in My 2017 Nissan Maxima SL! It still Performs well! The Oil Companies like the fact.that most Consumers are dum to this facts.

  43. The fuel does not differ in quality etc. Premium is only useful if your car recommends or requires it otherwise there are no benefits to premium

  44. Try putting 87 octane in your Japanese (Yamaha, Suzuki) motorcycle instead of 91 or higher and tell me it doesn't matter. Higher octane is for higher compression motors. I purposely carry several 2oz octane boost bottles on my bike in case I come across a gas station that doesn't have 91 or higher

  45. of course its gunna be the same figures in the first test what is important is throttle posistion with higher octane fuels you dont have to press the throttle as far open as with regular fuel hence the fuel economy

  46. I work for a major oil company and I did the testing on gasoline octanes for 5 years. Unless you have a car that requires it you’re throwing your money away. Don’t need it. I run 87 in all of mine which is the base octane fuel where I live.

  47. The best thing to do is get the ethanol out of gasoline, yes I know the farmers who get subsidies from the government are going to hate me but your wallet and engine will be lot happier with better performance.

  48. All I know is in the older cars we use to drive, if you put a regular low octane gas in your car it would ping and or run on. So a higher octane helped stop this. I guess in today's smart-cars the ECU will automatically adjust the timing preventing any pinging. I go by, today, what the manufacturer suggest you use.

  49. I had a car with a factory supercharger and it ran bad when I put the 87 octane in it would fall on its face it would lose power and knock sometimes

  50. This is very car specific. A 2019 mazda cx9 gets 25 hp with 91 vs 87.
    The manual should state 87 only, 87 or higher or both with hp ratings for both.
    If it says 87 "only" then premium does nothing.
