Looking to get maximum MPG from V6

I bought my V6 for MPG. I have a musclecar already. I am disapointed with the 19-20 mpg I have now. Has anyone done mods just for this? change spark plugs? does CAI and exhaust give much better mpg?

Alot of variables we need to help.

MPG is purely based on your driving habits!

no aftermarket part will considerably help you if you don't drive properly!

That MPG is overall. 80% city, driving carefully for MPG. If I really baby it, I can get 21 overall. In my R/T Dakota, changing plugs from platumum to Autolite standards gave me 2 more MPG. How much would exhaust and CAI add?

Nothing in a V6.

The only way to increase mpg is drive on the highway more or babying it in the city.

Using good driving habits can greatly increase your mpg in most cars.

the only reason the plugs worked on your dakota is because it was probably due for a tune up. i used to have a dakota and had to change the plugs, wires, & distributor stuff every 50,000 miles to keep it maintained.

with your camaro, especially since it is new, you will not need to replace the plugs until at least 100,000 miles unless you tune it and run it too lean or rich; only then would they need to be replaced sooner.

the V6 was rated at 18 mpg city and 29 mpg highway according to the EPA, so if your driving 80% city averaging 20 mpg, you are driving the car normal.

every fuel mileage improver on the market is a scam! it all depends on what car you have, how you drive it, and how you maintain it. an intake and exhaust will free up some horsepower, but will not improve your fuel economy.

The only other option for improving mileage? Get some miles on the car! My mileage at 1,000 miles was not nearly as good as it is at 3,000. Once the bearings, rings, etc. have seated and broken in, the mileage will improve with better oil flow due to wear patterns.

It used to be switching to synthetic oil (like Amsoil, and to a lesser degree Mobil 1) would get you better mileage, but on the newest engines? Nah, I don't think it'll help much. I plan to switch to full synthetic at 4,000 miles, but don't expect any significant mileage change. I'm just doing it for the better protection.

Do you live in a hilly area? Flat land with the cruise set at 55 mph gets me 30+ mpg.
