Why’s one better than the other? Also, my car 2016 328i x drive was given to me at 61,000 miles. Is there anything I can buy to put in my gas tank with the gas once in a while just to clean out the gas lines? I know they sell stuff like that why or why should I use it? If I should which brand is best? Thanks in advance everyone!
If I could pour ethanol free petrol I definitely would. Damn EU regulations require 10% of petrol to be ethanol, which causes a ton of issues in the long run.
