i am looking at a 99 chevy 1500
4x4
1/2 ton
5.3L v-8

what can i expect milage wise on this baby????

With everything good, around 18. Kevin says they run forever, but you may experience transmission problems around 150K. He says they're a great vehicle. Automatic or manual?

Be careful, Chevy had a lot of electrical problems in '99 and '01 in certain models. I'm pretty sure the trucks had theirs in '99, when they first switched over to the new body style. Other than that, they're pretty solid. Expect between 15-20, depending on driving style. Obviously it'll drop if you have it in 4WD a lot.

I have one.

Tranny at 175k
Anti lock brake module at 40k
Will rust on the drivers side cab corner and gas door

Overall a trusty truck. The tranny issues are the only thing that stranded me.

4 wheel drive is solid. Beef up the suspension, as it has a car ride feel to it. It will likely develop a slow oil leak around the rear seal for the engine..

Liz is correct on mileage. I need to replace plugs, so mine is down a bit right now, but fresh plugs will take it back to 18'ish.

the engine will take some getting used to if you are accustom to the older 350's. They rev a lot higher to get into the power. Good engine though..

They like to snap off manifold bolts too. The one is a real bizatch to get to, drivers side rear. My Brother inlaw (mechanic) replace 6 of them for me one day and said he didn't even attempt the last one. "it'll be fine!"

I have an 2004 5.3L V8and I get 15-18mpg.

C- h- e- v- r- o- l- e- t == crackked head ,every valve rattling,oil leaking everywhere today!

jeeeeezeeee.. grump..... way to brighten my day..LOL

I own 2 of the 99 vintage G.M.

My 99 5.7 L. Suburban will run 17-18 on the hard roads

My 99 7.4 L. Crew Cab Dually will run 14-15

expect 16-19 out of the 5.3

I have an 89 trap truck 17 mpg. My 2004 also 17. doesn't seem to matter what I do, 17 is the number. love both trucks.

I have a 2000 with a 5.3 that gets 14.4-15.6 consistantly. If I run her hard 80mph+ I get 13.3. Towing 2 sleds or 4wheelers with one in the bed I get 13.6. I have the dreaded electrical problem that I have had for 3 years (Disco lights on my dash). I lost my trasfer case in August but it has 168,000 miles on it. It is running great and loaded for hunting/trapping season.

I have replaced my 4wheel driver selector switch and that is the only other thing I have replaced. (other than batteries, brakes, tires)

o MAN,,, Get a TOYOTA.

Mileage wise, my 99 gets 16-19. Electrical problems in one taillight. One thing to have checked, if the truck comes from a state that uses calcium chloride mixed with the road salt, are the brake lines. They may fail, like mine did, every one of them at the same time, blowing apart due to the reactions with the calcium chloride is all my mechanic could figure out.

14 - 19 depending on which gearing is in the axle.

That is about what I'm getting with my yota....

15 tops in the pasture...

and if I pull anything it is less than that...

transmissions are a problem with these model chevy's, they added the overdrive but didn't change the size of housing for the gears.....i aint a mechanic just someone that knows about them told me that lol.

but with that said, i have a 2000 model chevy z71 i got 300k on it before the tranny went.

very dependable truck.

i get about 17 or so mpg. depending on the speed and towing.

I know I am going to get some flack for the non-dimestic but I bought a 2005 Nissan Frontier (4x4 manual) with less than 30k miles for less than $10k. All I do is change the oil. I get 20 mpg every tank. Pretty good value in my mind.

My 98 just turned 260k still at 18-20 mpg 5 speed, started going through a little oil at 225k, Quite afew in my area never see them for sale, Most guys run them till they quit.

Miller, I have an '06 Chevy and I average 17.3 mpg. The newer ones do get a little better mileage but what ever you do don't fall for the cheap ethanol fuel. It was $.50 a gallon cheaper when gas was high and since I have the flex fuel engine I ran a tank full of E85. It actually cost me $6.00 more for 20 gallons mileage wise versus paying more. My mileage dropped down to 12 or 13 running E85.
