so the other day my buddy calls me his truck is down and wont start. i give him a hand ended up being a dead battery. i notice the oil change sticker in his window says 147600 miles orr 11/07. i asked him about it he told me that was the last time he had his oil changed. i told him he should be having it changed every 5k miles or so. he told me hes had it changed maybe 4-5 times since he bought the truck new it 2001. its a 2001 chevy pickup with the smaller v8. it currently has about 210k miles on it. it runs decent too. always passes emissions here in phoenix area. he said hes never had a tune up done. the only work hes ever had to have done was replace a fuel pump. he has zero mechanical ability. i checked his air filter it was filthy he told me he didnt even know the truck had a air filter. id guess its been replaced at least the 4-5 times hes had the oil changed. ... this is insane to me. 210k plus miles and hes only had the oil changed 4-5 times and 60k miles since his last oil change. i changed it 4 him it only had about 3.5 quarts of oil and the filter was the worst ive ever seen. .... all this oil [censored] is b.s. on a regular normal performance vehicle. . . this is the most extreme ive ever heard of. he has a 2002 dodge caravan with 150k miles and he told me hes maybe had the oil changed 3 times on that becuase that is his wifes vehicle. and she never does it. how you like them apples
