On a 500 mile trip, I only got 23.7 MPG (calculated). The trip computer indicated 24.6.

 

about 25 hwy, 20 city and very happy with it... I calculate every fillup. A few tanks hwy i'm running maybe 23 but thats going 75 or so with take-off's not exactly like grandpa [img]smileys/smiley2.gif[/img]

 

About the same as everyone else. I can get 21-22 in town, back and forth to work... but a fair chunk of that is highway. When I'm on a true road trip, it's usually in the 26-27 mpg range, at or slightly above the speed limit of 70-75 mph. I suppose I could squeeze 30 out of it, if I tried. (Not very likely)

I fill my tank and manually calculate it for every tankfull. For the most part, the trip computer is usually a little optimistic, but I've seen it on the low side as well.

 

</>lately mine's been down a bit but I've been running around 75 or so and trying to beat everyone at the red light hahha

check out this site to help you get better fuel mileage. http://www.lubedev.com/smartgas/I use acetone in my gas and it helps in many ways. my tail pipe has no black soot like many other cars that I see. it cleans your engine, gives better mileage.

 

cost me $500 a month to run that big one, so went out today and bought me another chevy. figured i better stick with the poor man's cars.... not planning on getting another big one again in a good while.


Getting 15 mpg hwy was too much for me. the 3400/3500 V6 from GM getting 34 - 36 mpg so that was my only out...

Sounds like snake oil to me. I read a few paragraphs of the link, rambling chemo-babble, IMHO.


Have you actually figured what mileage gain you are getting? Have you compared cost including the snake oil? (i.e. $/mile vs. $/mile)

Are you sure that is good? It maybe in your engine......[img]smileys/smiley11.gif[/img]


If you have a late model car that you care about, don't add questionable crap to the gas.....there are a dozen sensors in that engine that you could cause to malfunction.


Say you drive 1000 miles a month, and you THINK this snake oil improves your milage from 30 to 33. That is about $9 a MONTH you are saving. How much is a bottle of this stuff and how many did you buy in a month??[img]smileys/smiley3.gif[/img]

 

I am getting 17mpg in mostly city driving. since it has a 19 gallon tank(compared to my trucks 26 gallon tank)I have to fill it up about twice a week.

 

18 city(lead foor assisted.custom of course HAHA) and about 25 highway is the best ive gotten highway and best city was 20 even so not bad for a mildly modded engine.
