What happens if I use 91 octane instead of 95?
If you use 91 octane fuel instead, you can expect reduced vehicle performance because the car’s on-board computer will receive information via the knock sensor and alter the ignition timing. But there won’t be any damage caused, at least in the short term.
Which fuel is suitable for my car?
Carmakers design engines for a minimum octane rating. If you open the fuel flap of your car and it says ‘unleaded petrol only’ it means 91 octane fuel is OK. If the fuel flap says ‘premium unleaded only’ it means you need to use at least 95. If the fuel flap tells you to use 98, that’s what you need to do.
Which fuel is best and why?
The higher the octane number is, the more resistant the fuel is to pinging in your engine. For this reason, it’s recommended you fill high-performance cars with higher octane fuels, such as 98 premium unleaded petrol, since these cars are more likely to burn fuel consistently at higher temperatures than regular cars.
Is Shell fuel better than supermarket?
Their fuel is portrayed to have a higher quality and be better for your car’s engine. Retailers like BP, Shell and Esso sometimes put additives into their fuel to help boost the fuel efficiency of your car. This means that fuel from supermarkets, without these additives, could be costing you more in the long run.
Why is Shell fuel more expensive?
Since most end product stations have equal research, they can produce similar additives. The most likely scenarios for Shell gasoline to be more expensive is that their additive is more expensive to add, or that other stations are using the base gasoline from the local distributor refinery.
Is BP better than Shell?
