What is the difference between 91 and 95 fuel in Saudi Arabia?
What is the difference between 91 and 95 fuel in Saudi Arabia?
What is the difference between octane 91 and 95? The difference between the 91 and 95 octanes is the 4% change in the octane levels. Octane 95 gasoline is more flammable and lighter than 91 gasoline. The internal combustion engine performs better with higher octane numbers.
Is 91 and 95 fuel the same?
Put simply, 95 RON is a just a little more ‘stable’ than 91 RON and resists pinging longer, allowing the engine to do its thing properly. In the process, the more highly tuned engine is a little more efficient, meaning it can make a little more power on the same volume of fuel.
What happens if I use 91 octane instead of 95?
It won’t hurt your engine if you use a higher octane fuel. For example, if you use 95 or 98 in an engine designed for 91, that’s fine. However, avoid using a lower octane fuel than the minimum recommended by the manufacturer. Using 91 in an engine designed for 95 or 98 is potentially destructive.
Is 91 or 95 fuel better?
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.
What is the difference between unleaded 91 and 95?
The general rule of thumb is: the difference in fuel efficiency is about 1% per octane rating – 91 and 95 unleaded fuels, for example, have roughly a 4% difference. If there is a lesser price difference between the two, then its highly likely that its worth switching.
What is Aki 91 fuel?
The AKI is an average of two other octane numbers, the RON and the Motor Octane Number (MON), which are determined by two different laboratory tests. For example, a 95 RON plus an 87 MON averages to a 91 AKI, which is the octane rating you would see displayed on a U.S. retail fuel site dispenser.
