From what i read that is "combined". With a C4, that is very good mileage for a 6 cylinder. That is what the 6 was all about.
MP,
What's this I'm reading? you are going to drop a V8 in your baby? Ohhhhh, you are in big trouble now little missie!
Soaring's gonna hear about it. Then what are you going to do?
An easier way to check your mileage is just to average it over 3 or 4 tanks. Same station, same grade of gas, same pump (if posible). it will get you plenty close enough.

If you don't drain the tank then add an exact gallon number , then check it again after that exact number of gallons runs out, you will not get an accurate figure. However, if you you fill your tank just until the first click of the filler, then you may get a more realistic number. How many of us do that though?And, how many of us wait a few seconds to pump in a few more gallons once the bubbles subside? How many of us actually push down on the rear fender to allow more fuel to enter the tank? There are obviousiouly a lot of variables here. I would think a 6 banger would get better gas mileage than my 289 2V though.

RE: Gas mileage
You crack me up Soaring. How about this. Divide 164 miles into 1/2 gallon. How many mpg is that? Now if you can't fill your car up to within a half gallon each time you go to the pump, well,... then something else is the problem.
You'd be amazed at how accurate this can be.
Heck, don't believe me, read up on some articles that talk about how to check your mileage. Or better yet. Try it for yourself.
Triple A, CSAA, Old timers anonymus, etc. have all done articles on fuel mileage. I get a lot of information from trade journals. Every now and then you'll find an article in there.
Of course it could all just be a big conspiracy. It could be one old article that is wrong, and every automotive journalist is just parroting it.
Want to know another "big secret". The average American that keeps track of their mileage, will get better gas mileage.

RE: Gas mileage
Pammie has a GREAT ONE for her V8 ride.. Its a sweet one too.. If she does it right, she can get nearly the same mileage from the big V8 as she does from the I6. its called a Qjet and a light foot with reasonable gears, possibly an overdrive.
how I check mileage in my vehicles. There is a digital readout that shows me how much fuel I put in it to the .00 gallon. So lets say i drive 330 miles in the ol LS1 urged daily driver and it takes me 12.46 gallons to fill it untill some dribbles out. I am adept at knowing when it is full and when it can take a little more. So we divide 330 by the 12.46 and we get 26mpg.. Now if I have been hotrodding around and doing mainly city driving that is about right. Usually it takes about 11 gallons to fill it at 330 miles on the highway. I check it every time I drive long distance, and that is a few times each summer, and then average it out over the month or trip. Not bad for a 305hp rated 5.7L V8 is it? The winter car beater 97 dodge intrepid gets around 28-32 depending on the fuel we put in and how much we sit in construction areas...

RE: Gas mileage
Ummm, no. That's isn't a real efficient method of tesing gas mileage. Even the factory will suggest keeping records for 3-5 tankfulls (it's in the book for your Mach) and calculating the mileage over that period of time.
I keep track of every fill up and keep a running average through Excel. A little over the top, but you can be sure the mileage is accurate.
My '71 has been averaging 14mpg with 3.80 gears and anything-but-economical engine or driving. Before modifying it, I would average over 19mpg.

Have you ever run your tank empty in order to check the exact amount of fuel you need check just how far you can run on the freeway with only 10 gallons of fuel?

RE: Gas mileage
Not to check fuel mileage, and the only time I would consider running a tank empty would be with a new tank, or an old crapped out car where I wasn't concerned about the fuel system or engine. I don't like sucking up all the crap out of the sump area. I'd never recommend it on an EFI car. Great way to burn up a pump.
Wanting to know how far you can go on empty, is kind of old school. As you reach the bottom 1/4 of a tank your fuel mileage decreases. The amount of decrease depends on the size, location, temperature, road conditions, etc. It's just not a real accurate way to check, unless that is how you intend you use your car in normal operations.
I prefer using a quarter tank as a minimum line, and figure out how many miles on average I can go before I hit that mark.
