What is a good octane rating?
Retail gasoline stations in the United States sell three main grades of gasoline based on the octane level: Regular (the lowest octane fuel–generally 87) Midgrade (the middle range octane fuel–generally 89–90) Premium (the highest octane fuel–generally 91–94)
Which fuel grade should I use for my Toyota vehicle?
Modern engines are equipped with sensors that can take care of pre-ignition and minimize the damages, but there is a still a slight chance. So, bottom line is stick to the recommended 87 Octane. That is peak efficiency for your Toyota.
Which gas is better 87 89 or 93?
Regular gas is rated at 87 octane in most states, while premium gas is often rated higher at 91 or 93. Engines with high compression ratios or turbochargers often require high octane fuel found in premium gas for optimal performance and fuel efficiency.
Does premium gas give more mileage?
Premium gives better gas mileage Because premium gas has a higher octane rating than midgrade or regular gas, it produces a little more power when burnt. Designed for performance cars with large, powerful engines, premium also helps minimize the risk of preignition inside highly-stressed, hot engine cylinders.
Is it worth using 98 octane fuel?
It can’t hurt your engine if you use a higher octane fuel. So, for example, if you use 95 or 98 in an engine designed for 91, that’s OK. If you run them on a higher octane fuel than the minimum recommended, you will get either better economy or more performance (depending on how you drive).
Is 98 RON fuel worth it?
According to NRMA motoring expert Jack Haley, on average 95 RON can give around 4 per cent lower fuel consumption than 91, assuming the engine computer adjusts to take advantage of the octane difference. Using 98 might give 3 per cent reduction over 95, again assuming the computer adjusts the engine parameters.
Will 110 octane hurt my car?
It will not hurt your car in any way, but it will cost you more – for no benefit. Most modern cars with engine computers will try to adjust the engine for a lower octane, but that reduces engine performance and increases fuel usage.
Can higher octane hurt your engine?
The higher the octane, the greater its ability to prevent the unruly type of combustion engineers call detonation. The goal is to ignite the fuel mixture solely with the spark plug, rather than from the heat in the cylinder, to prevent detonation, which can seriously damage high-performance engines.
Does premium gas give better mileage?
What happens if you don’t use premium gas?
If the octane rating is less than 91, you could damage the engine and may void your vehicle warranty. They usually warn that using lower-octane gas could reduce performance and fuel economy. When that happens noticeably, or if engine knock occurs, they advise to start using premium.
