The myth of Midgrade Gas



We were very interested in my last video about Midgrade Gas how few cars need it, and the plan to upgrade all to Premium. Still, many of you seem committed to using Midgrade, so we've spent more time exploring it and finding it both myth and hackable.

First the myth: Most refineries do not make midgrade gas. They do regular and premium and that's what's underground at the gas station. When you press the middle handle, you get a cocktail of the two fuels, "splashed" while you pump. Thanks to the EPA, because in 1

988 and 2015, the underground storage tank regime was tightened, causing many gas stations to dig up and replace their old gas storage facilities. When they installed new ones, they often installed only two and started to mix spontaneously.

Now a tip: If your car is rated for Midgrade gas, you can save money by mixing your own. Give some of the normal pump off, start a new transaction and pay the rest of the premium pump off. In states like California, where our grades are often evenly spaced at 87, 89 and 91 octane, it's easy to figure out the proportion. A 50/50 split of normal and premium gives you 89 octane in midgrade. If you do, you can save 5-10 cents per gallon on the stations we are looking for.

I know people who will drive miles to save this, even though I'm not one of them.

Finally, since you know that Midgrade is a partial premium, does that mean you get some of the other benefits, such as engine cleaning? Probably, but measuring the value of proprietary additives is something between black art and religious prostration.

Instead, follow the AAA's recent recommendation to use top-of-the-range fuels that have a measurable advantage in engine life. Gas station brands participating in the top tier must offer this benefit, regardless of the fuel grade or other proprietary additives they may have.
