I just bought an 05 Acura TSX with just over 5,000 miles on it. The recommended oil weight is 5w30 for this car. Should I use Mobil 1 5w30 or GC 0w30? Do you think GC would be a good match for this engine?
Obviously, check the UOA section to see if anybody has any reports on GC from your engine. But beyond that, I don't see why you shouldn't use it. I'm getting ready to make the switch from Mobil1 to GC. I've used Mobil1 for 85K miles in my 100K mile Grand Am GT. My engine is spotless. So, I really think highly of Mobil1 but I also like change and I've heard enough good things about GC that I'm willing to give it a try.
