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?
Everyday AutoZone and O’Reilly’s have the fuel system treatment stuff on sale up at the register. Whether it helps anything is debatable, but it definitely will not hurt anything and it only costs a few dollars. With that many miles run it with every tank of gas and see what happens.
