I never used any additives on the fuel since most friend mechanics told they didn't do much than take your bucks. But I am willing to give it a try on this occasion.
Hey, as pointed out in this thread, 95 octane won't have any real benefit unless you get an engine tune using something like a FlashPaq and you can then take advantage of the higher octane. The higher octane is really only there to prevent pre-detonation of the gas. Also as said, some of the (Oil) companies put fuel additives which supposedly help keep your fuel system clean but the amount is really minute and you would need to only use that brand to ever accumulate enough of the additive benefit.Can using 95 oct on the 13 jk do any harm? I usually do a fill of 95 on my 2017 rav4 once a while to clean the injectors?
