I have an old Chevy POS pickup. It's well over 20 years old, rusty, burns a little oil, high on KM's and has basically led a neglected life before i bought it. I have been doing regular upkeep on it to keep it running, but i haven't done anything special. Just oil changes, replacing parts here and there when they decide to crap out, etc.
Every year i get a little apprehensive before i take it into aircare. Last year it didn't do too bad, but i didn't even let it warm up before i took it in. Check out today's results!
