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?
Do you have the 2.4 4-cylinder ecotec motor?
There’s problems with the timing chains and they’ll start to Make some noise every now and then as the tensioner wears out
Also, there’s a PCV hole that has to be cleaned out on the intake otherwise it can blow the rear main seal on the same motor
