Choosing the right type of fuel

Dear Tom, Thanks for your answer , the problem is that the RON 95 fuel is 3 times the price of the RON 92 fuel, what i need to know is will it cause any engine damage on the long run, my engine compression ration is 10.5 and it has turbo.

Thanks Tom for your answer, when I bought my car the price difference was slight but suddenly the government decided to take their support for RON95 and take prices up crazy like that :( Thanks again

Do you have Fuel additives such as Octane boosters where you are from. Usually available from Auto accessory dealers. This could be the answer to your dilemma. Other than that Tom is correct your car will be fitted with a knock sensor which will tell the ECU to retar

..d the timing and prevent any harm to the engine.

Thanks Paul for your answer, yes i could get fuel additives like Stp but i heard they don't do that much enhancement also they might cause some problems with the injection, that's what i heard if i am wrong please correct me.

Most additives are like headache tablets, they work well as long as you read the instructions and take at prescribed periods. They should not cause any problems as your engine is designed to take higher octane fuel as standard, here in the U.K we run on mainly 95 Ron unleaded fuel, previous to that we were running 98 Ron leaded!! real man fuel.. lol

Thank you for your helpful answer.
