I have a GMC terrain 2017 with over 270,000 miles. Hardly any problems with this car. Lately is been making slight clicking noises after driving over 4 to 5 thousand miles and when I changed the oil they put a small bottle of gas treatment in the tank and the clicking noise went away. Then again after certain miles close to have the oil change again started with the clicking noise so I repeated the process with the gas treatment and clicking went away. My question is will it be a good idea to put premium gas to the car? Will better gas will keep the clicking away until I take it to my mechanic?

    I use premium for mine because it now has carbon buildup and will ping with regular. Premium also retards timing in an engine. For my vehicle it keeps my check engine light off. Started using premium since 120k miles and never went back once i noticed it would stop pinging.

      Premium does not retard timing. It allows the ecm to advance timing. Yours did not stop pinging due to timing retard. It stopped pinging because low octane fuel was not detonating.
