gas mileage question
hi, i am buying a 1999 chevy silverado with 45k miles. it is a reg cab truck with a 6 ft bed. also the motor is a v6 4.3L
i am wondering on how the gas mileage is on the truck from personal experiences cheers justin |
RE: gas mileage question
I would say not too bad on a 4.3 single cab. I own a 2000 ext cab 4x4 with the 5.3 and I get around 15 in the city and somewhere around 18 to 19 on the highway so you should see a little better than that I would think!

RE: gas mileage question
Get a truck with a 4.8 as the 4.3 won't get enough mpgs over the 4.8 to make it more affordable. You will lay into the pedal more so there will be time where your mpg gain over a V8 will be 0.
Few questions tx_cowboy: Why only 15-19 on your truck? You think its bewcause of the dumped exhaust? You try programming it out? Removing TQM? How did the conversion go with the Electric Fans? Was it worth it? Can you tell the difference? |
RE: gas mileage question
I had an s-10 with the 4.3 it is a great little motor, I got about 18 city and highway. The silverado is a little heavier so I would expect 15-17 mpgs.

RE: gas mileage question
ya thats what i was expecting. i will be either putting a 4.8 or a 5.3 over the summer.

RE: gas mileage question
I wouldn't do that either. Just build the 4.3 up a little and you'll be fine. Throwing 2-3K at a basically new 4.3 is better than swapping it for 4.8 and spending more for the same output.
If the 4.3 is that new (45K) just keep it and build it up. |
