How about that Honda?
 
I filled up my 1996 Accord LX (2.2L 4-speed Auto) yesterday, and thanks to my local stations now using 10% Ethanol, my mileage has hit a new low of 25 MPG. I was averaging over 27 in a mix that is pretty highway-heavy.

I have never really studied water injection but know it has been a performance enhancing technique for years, and as mentioned herein, suppresses detonation.
There was a world record holding Corvair back in 1965 tested in Hot Rod magazine where the guy had modified the intake system to include a 4 bbl carb, and a water injection/turbo system with a high performance Isky cam. The car was street legal and ran 163 MPH on the Bonneville salt flats. "Normal" turbocharged Corvair would top out around 110-115.

Last week I ran a bottle of STP fuel injector cleaner, don't know if it actually works. Anywho, my latest mileage, filled up today, was 27.726 mpg.
 
Are there any "fuel injector cleaners" that actually work? Just curious. I know stuff can build up in the engine, but is there really a product, that if used regularly, will clean some of the deposits up? I know some who don't bother figuring they're a waste of money, and others who swear by them. Just curious to find out from somebody who knows.
 
Thanks again.

I've been using Chevron's Techron fuel system cleaner for years (concentrate) on the advise of a mechanic friend of mine. I put a large bottle (up to 20 gal size) every 5,000 miles. It may a bit over kill but I'd rather be ultra-clean then have it work toward removing any build up. So far, so good...
 
On a separate note, my 2005 4 cylinder accord has the nav system and, although not entirely accurate for fuel consumption, I do keep the Trip Computer screen on while driving as it helps to keep my "honest" while driving. With that mpg bar graph, I can see how efficiently I am driving.
 
Anyway, I'm lucky in that I travel mostly highways to and from the office. Until mid-April, I always hit the cruise control at about 60 or 62 mph and just tooled along.
 
When the gas hit a "new" high in mid-April (again), I hit the cruise control at 55 mph and you would believe the impact it's had!! Lots of angry drivers passing me but I always catch up to them at the exit or the toll, or...
 
At 60 - 62 mph, I was (according the nav) getting about 400 miles out of a tank.
 
At 55 mph, the nav tells me I'm up to 500 mile per tankful.
 
25% increase!!!??? Now THAT'S significant.
 
I also have my tires inflated to 40 psi (the michelin's are good up to 44 psi). makes for a little harder ride but at just short of $4 per gallon, I can deal with it.
 
Been keeping the 40 psi ever since I bought the car in April 2005 and finally changed the tires just before Christmas with 60,000 miles on the car. So the extra psi had virtually no impact on the wear of the tires (contrary to what lots of folks say).
 
Just thought I'd pass that on - again, the nav isn't the be all and end all, but it DOES recognize the load under which the engine is at any time and the numbers have been consistent for over a month now.
 
25% guys...
 
Oh - by the way: the 5 mph difference adds about 2 minutes to my commute (in case anyone wanted to go down THAT road).
 
All the best - drive safe and smart

That's an extra 2 minutes, count em 2 minutes, that I could stay in bed sleeping or dinging around home.
 
My morning commute is probably the most fuel efficient around. I usually take about 4 miles of freeway, and the rest is stop and go, but on the stop and go portion it's a main drag and at the time that I am going to work it's about 3:45 am so most of the lights are green when I hit them. Meaning that my average speed for that portion is about 43 mph with minimal stopping.
 
If only my afternoon commute would be a little smoother.
 
If only everybody had the patience to figure out what the difference is when going slower. I could probably do just fine going that far under the limit. Maybe I will try it. I usually have about 10 minutes before I have to be work and on the clock anyway by the time I get there.
 
I'll have to report back. Just filled up today. I'll be seeing you soon.

I wasn't kidding about the angry drivers, though... I wear sunglasses so that i can steal a peak in the rear view mirror every once in a while to see just HOW po'd the person behind me getting.
 
They pass me like I'm standing still...! Amazing
 
Maybe I should stay out of the fast lane...?

Your right about the Techron I once leased a 1986 Audi 4000S had a little problem 2 year later an the tech said to use it after one tank ful the hesitation disappeared.
 
Also what size tires do you have, I have th 08 Accord LX-P 16" what is the highest PSI I can go with.

You know you're right about wearing sunglasses just to catch how p'oed they are. I've almost contemplated aiming my mirrors all the way in to the sides of my car just so I wouldn't have to look at those behind me, but I've come to rely on them more for lane placement than anything. I don't use them to change lanes, it's just one more step when you have to look over your shoulder anyway. I guess I try to keep up to avoid road rage situations, but I guess in the era of $4+ for gas coming soon it's time to be a little selfish.
 
On a side note I did the math and the difference between going 70mph versus 55mph when boiled down to the minute is 1.166 miles/minute and 0.916 miles/minute respectively. Which means that we really aren't getting anywhere too much faster at the higher speed.
 
That difference is going to be greater 55 vs 80, but anyway. In terms of short distances the difference is minescule. Sorry I can't spell. I figured that if I were to go exactly the speed limit, my commute would only be lengthened by 1.2 minutes.
 
You can check my math, I may be off.

Packer - I have 205/60/16 but I don't know what your max psi would be. I just looked at the sidewall of mine and saw 44 psi. Since the car calls for 30 something, I figured I'd beef it up to an even 40 and kept it there ever since.
