maintence

I have 2000 blazer, 4x4, would sort of regular maintence should I do, what kind of tune up, how long should the fuel filter last?

don't worry about the fuel filter but in regards to the tuen up i would wait till she start running rough then to the plugs and stuff cause it is expensive the do on the the new one. but other wise just make sure u do all your oil changes on time and if u are gonna change the tranny oil u have to be faiful and go by the service manual exactly or u just don't do it. during the time u don't use the 4x4 like the summer months make sure u take the time and to make the truck shift in and out of 4hi and low several cause if u don't later on in life it will gum up and not work when u need it and that means$$$$$

gm says to replace the fuel filter, air filter, pcv every 30,000 and the tranny fluid every 50,000 do the spark plugs at 100.000 leave the wires if you dont need to replace them. and dont be a hack and wait for the truck to start running bad before you do maintanance on it.

its not being a hack it just common sense if it isn't broken don't fix it 9 time outa 10 u can just take out the platnum plugs and clean the deposits off and put them back it

what kind of sevice? the only maintenance your truck needs is for you to change the tire air every 3k miles. it has self filling and cleaning oil so don't worry about that.
