What E is 87 gas?

What is octane rating? Octane rating is the measure of a fuel’s ability to resist “knocking” or “pinging” during combustion, caused by the air/fuel mixture detonating prematurely in the engine. In the U.S., unleaded gasoline typically has octane ratings of 87 (regular), 88–90 (midgrade), and 91–94 (premium).

Is E 87 regular gas?

Gasoline with an octane level of 87 is considered “regular,” with gasoline sold at 89 octane often labeled “midgrade” by most gas stations.

What is the difference between E85 and regular gas?

The Differences Between Ethanol and Gasoline Blending ethanol and gasoline at a ratio of 85 percent to 15 percent (E85), the blended fuel is nearly thirty percent less powerful than pure gasoline. Ethanol is similar in acceleration, power, and cruising ability, but ethanol miles per gallon are less than pure gasoline.

What’s the difference between E85 and e87?

Because of the poor implementation of flex fuel on vehicles you probably won’t see much difference between 87 and E85 except potentially lower mpg when running E85. BUT, if your vehicle is running an aftermarket tune for E85 and you put 87 in the tank your car will choke with fuel as E85 tunes are richer than 87 tunes.

What is the point of 89 octane gas?

Higher compression engines need higher octane in order to run properly. Thus, 89 can solve knocking problems on some older engines.

Is it OK to mix 87 and 89 gas?

You won’t damage your engine at all if you use a higher octane – you’re just wasting money. In North America, service stations blend the higher octane (like a 92 or 93) with a lower octance (87) for the mid-range fuels (89-91) so you’re really not getting your money’s worth.

What happens if you put 89 gas in a 87 car?

If you usually fill your tank up with 87-octane gasoline and you accidentally put in a higher octane blend (say, 91, 92, or 93), don’t worry. You’re actually filling your car or truck with a different blend of gas, which means it will burn differently in your engine.

Should I use 89 gas?

Let’s start with the easy one. Most cars on the road recommend a standard grade 87 or 89. Premium gas 90-93 is completely okay to put in a standard vehicle. Car experts say there is no risk of damage to a standard car using premium fuel.

What is the highest octane fuel?

The standard octane fuel for most vehicles as of 2012 had a RON of about 92 and a MON of about 82, giving it an R+M/2, PON or AKI of 87. High octane fuel for cars typically is considered anything with a RON of 95 or higher, a MON of 85 or higher and a R+M/2 of 90 or higher.

Is ethanol-free gas bad for your car?

The short answer is, no, ethanol-free gasoline is not bad for your car. Most cars today can run on ethanol gas blends up to E15 (15% ethanol) and on non-ethanol gasoline. And flex fuel vehicles can handle up to E85 (85% ethanol) without a problem.

What is regular 88 fuel and can I use it?

Regular 88 (otherwise known as E15 or Unleaded 88) is an 88 octane fuel available at many Family Express® locations. This grade of fuel contains up to 15% ethanol. Regular 88 is EPA approved for use in model year 2001 and newer cars, light duty trucks, and flex fuel vehicles. Regular 88 is not only available at a lower cost, but also delivers optimum performance with a smaller amount of emissions.

What is 89 octane fuel?

And since 87 is the standard octane rating for the fuel most engines use today, the 89 and 93 octane rated fuels are only different because they can handle more heat and pressure before igniting on their own. This, in turn, means they can run in performance engines designed to use higher compression ratios.
