What will be the octane number of best fuel?
The higher an octane number, the more stable the fuel….What is octane?
- Regular (the lowest octane fuel–generally 87)
- Midgrade (the middle range octane fuel–generally 89–90)
- Premium (the highest octane fuel–generally 91–94)
How do I know what fuel octane is in my car?
How to identify what octane your car needs: First, open the fuel filler door. Next, look at the gas cap and the inside of the fuel filler door. One of these should have the recommended octane fuel for the vehicle written on it.
Does 95 octane have ethanol?
Premium unleaded is both 95 and 98. The ethanol-blended E10 (a mixture of up to 10 per cent ethanol in petrol) is a substitute for 91 in most cars 2005ish or newer. However, it pays to check your user manual. Those numbers – 91, 95 and 98 – are the so-called ‘octane rating’ of the fuel.
Will 89 octane hurt my car?
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 octane rating of regular gasoline?
Gasoline ratings have been determined on the basis of octane; 87 octane is regular, 89 octane is mid-grade and 91 or higher octane is premium. The octane ratings are not an indication of performance, but instead, indicate the fuel’s resistance to pre-ignition.

Where does the name normal octane come from?
Of the 18 isomers of normal octane (C8H18), octane gets its name from the 2,2,4-Trimethylpentane compound, which is highly resistant to auto-ignition. This iso-octane has been assigned the reference value of 100 for testing purposes. The extremely unstable normal heptane (C7H16) molecule is the 0 octane reference fuel.
Which is more important RVP or octane rating?
Fuel RVP rating is equally as important as the octane rating. Gasoline refineries raise and lowers fuel RVP ratings seasonally to account for the differences in temperature. Note: LOOK BEFORE YOU PUMP! Do not use unapproved gasoline, such as E15 and E85. Do not mix oil in gasoline or modify the engine to run on alternate fuels.
