My El Camino has been sitting for about 10 years due to me being in the Army and away from home. I finally got it back and am curious besides changing the battery, belts, hoses, plugs, wires, tires, alternator and flushing the system what else needs to be done to get it back up to par. Also before i left i had the engine and transmission overhauled, will me trying to crank it without dumping the old fuel and transmission fluid damage my car? And since it was overhauled shouldn't it be in better condition or can 10 years have ruined it? I've recently seen advertisements about STABILT and Z-MAX supposedly they rejuvenate and lubricate the engine if this is true or if theres any product that would help please let me know it would be greatly appreciated.
