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!
Great callout, I took an assumptive leap here and forgot about e85. It seems like the prudent call to dilute with premium for longevity. Yet to see a fuel pump in North East USA with e85, would love to have the option though
