i have a 1994 chevy g-20 van i bought back in 2001. it had about 53000 miles on it at the time and now has almost 120000. i have not had to do much to this van outside of regular maintenance. it still has original belts, and the same tires. i have never replaced the fuel pump, water pump, starter or any sensors. about all i have done is fix a minor oil leak and replaced the front brakes and a new battery. of course keep it tuned up and lubricated.it runs like new , never burns oil and starts right up no matter what the temperature. is this normal or did i just get lucky?
