Does it really matter if you don't use high octane fuel in a turbo engine?

If your car was a performance type car with high compression ratios then you would have to use the higher octane fuel to prevent what is called spark knock. Spark knock sounds like little hammers hitting when you are pulling off fast or climbing a steep hill. If you don't hear any spark knock keep doing what your doing and tell the mechanic you use the 93 he''ll never know.

I did a test on my vehicle with regular and high test gas and the results were the same gas mileage so don't let the internet experts tell you it makes a difference.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
