What is the BEST Fuel to Use in Your Car or Truck and WHY

Ever wonder what grade gasoline should you use in your car (what octane)? Are you paying for premium gas when you can just use regular? Are you using regular and damaging your engine? This video will bust all of the myths and tell you the FACTS on what fuel you should use and why.
Many people throw money away and fill their car with the incorrect fuel every day. Running premium or midgrade in a car designed to run regular is a waste of money and has no HP or MPG benefits. You will not make more power or get better fuel economy running premium fuel if the car manufacturer tunes the car to use regular gas in most cases. I also see some people run regular gas in cars that need premium and the knock sensors have to adjust timing significantly to prevent damaging engine knock. I also hear a lot of people say that premium gasoline has more energy or burns cooler or slower so I will put a rest to all of these "myths" with facts.

  • Technically you are correct... all 4 grades have the same amount of energy in them BUT the difference is how the engine uses the fuel with different octanes. As you mentioned, a high compression engine cannot use a lower grade fuel as well (the spark knock is a symptom of this). I run the highest octane I can get in my CTS-V but I also have a 99 Mazda that I use for a work beater that I picked up with only 43K miles on it and in that car I can see a significant increase in power and acceleration if I use 93 Octane fuel despite the manual calling for 87 so that is not always true.

I beat the hell out of an F350 crew turbo diesel for 240,000 miles....to the tune of $1/mile. 2 years into the purchase I realized what a scam "sticker" price is. Literally the year I bought it diesel prices went ABOVE regular for the first time ever and never reverted (1999). Now I demand better for my money. IF I'm paying $40,000 it better be a tank running on 50 cents a mile lifetime ownership cost or forget it.

  • In Wisconsin we have an 88 octane with 15% alcohol and cheaper than 87 octane with 10% alcohol. The pumps say only for cars newer than 2005 (I have a 2007 Saturn Ion). I tried one tank of this stuff, and before I refilled, it melted my flex pipe (it was a crappy, stock, flex pipe) by burning too hot. Or it could of been a coincidence.

  • I'm a chemist and have worked in a lab testing gasoline and diesel. This is for the protection of the consumers in our state. I'm pretty sure most states have a lab to do this. Most of the information in your video is correct and very useful. Thank you for making sure to emphasize the octane rating you see at the pump is NOT the energy content of the gas. It's all pretty much the same between 87 and 93, unless of course it has a higher percentage of ethanol (Uh can we say E-85? why would someone run this fuel 🙄). Ethanol will decrease the amount of energy in the gasoline, but it's added to make the gasoline burn cleaner and is good up to 10%. Something you didn't emphasize enough though is what "octane rating" actually is. It is NOT the amount of octane in the gasoline. There is little to no octane actually in gasoline (octanes are eight carbon hydrocarbons). The octane rating is the "equivalent amount of octane" in the fuel so that will resists knocking as if it contained that percent of octane. Gasoline is mostly made up of mixtures of toluene, and xylenes. If you ran pure toluene as your gasoline, you'd be getting about a 110 octane rating, but this wouldn't necessarily be good for your engine. When gasoline is made, the manufacturers control the mixture of hydrocarbons to get a clean burn and the proper vapor pressure (vapor pressure is the pressure of the vaporized gas above the liquid, not to be confused with the engine pressure). Also the gasoline must be protected from oxidation (this is why you add fuel stabilizer when storing for a long time) and contamination like water or particulates. Every brand of gasoline has slightly different proprietary ingredients to do this (as you've said at about 6 minutes). Also, the time of year will dictate what vapor pressure the gasoline manufacturers must make the gasoline to deliver to the consumer. Forget octane boosters. A pint of octane booster won't raise the octane rating of a full tank of fuel enough to make a difference. If you have a high performance engine that's been engineered for high compression, you're going to know you need a higher octane rated fuel. You aren't going to hit that 87 button. Are you?🤔 By the way, most mid-grade pumps, mix (in the pump itself) two parts of 87 with one part of 93 to get 89. But if you look at the price per gallon, they usually give you the "mid-price" between 87 and 93 for the 89. You'd be better off cost wise, by pumping 10 gallons of 87 and 5 gallons of 93 if you really want 89. I suppose mixing it well enough in the tank might be problematic for the first few miles. Really, you didn't need the 89 anyways. Octane Rating Tests Explained: One more thing you didn't explain well was how we get the octane rating in the USA. Yes RON stands for Research Octane Number. It refers to an actual test engine and ASTM method D-2699 for testing the octane rating of spark ignition fuels. My lab uses a RON called a Waukesha RON engine. It varies the compression of the cylinder to make the fuel knock while holding other variables at constant values (temperature, fuel/air mix, engine speed, etc). There is another test engine my lab uses, it's called a MON or Motor Octane Number engine and ASTM method D-2700. It too is a Waukesha engine that varies the compression of the cylinder but holds those variables at different values, mostly the engine speed is faster on the MON (900 rpm instead of the RON's 600 rpm), but I believe the inlet temperature of the RON is also kept higher. The RON and MON tests give slightly different results for octane rating due to the differences in these other variables. MON is always lower than the RON, by about 10 octane ratings if I remember correctly. In the USA, when you see the (R + M)/2 on the pump's octane rating label, it's telling you that the gasoline is rated by testing by both the RON and MON methods, and the final number you get is the average of the two test results. I rarely hear this average referred to as "PON", but I know it's not PUMP Octane Number. I had to look that up and if you want to trust Wikipedia it stands for "Posted Octane Number". In Europe, they only test with the RON method, as you've said, so this is why their octane ratings are higher. They don't have the lower MON test averaged into their octane rating. Great information in your video for all consumers. I gave it a thumbs up. 👍
