It was a dark and stormy night...And I got a 40+ mpg tank!

A few months ago I sold my 4 cylinder accord because I found my dream accord, a white V6 6MT sedan with ivory interior. So far the V6 has really impressed me with its mileage, although it was a step down in gas mileage, it wasn't as big as I thought it would be. The V6 has about 84 more horsepower than the I4, 256 more pounds, and an extra gear, the thing I was really looking for. Despite the low city rating of 18 MPG, this thing could probably beat the I4 mileage-wise in a short trip of less than 3 miles from a cold start. I blame the pre-cats.

Since I have a new commute from when I had the 4 cylinder, I can't directly compare mileage, but I have had enough highway trips to compare those. So far I have been getting around 36 mpg, until I adjusted the valves and cleaned out the intake manifold and runners. After the service, the car felt more responsive and about 10 hp more powerful. Then on my next commute i got 40.3 MPG! Best trip in the V6 as of yet! Clean out your intake!

I have not done much modification to the car yet because Iím busy with college and I need more coroplast and ideas, but I have done some stuff. When I first got the car I noticed that it had DRLs, those had to go. I pulled a few fuses before finding the right one, a little 10 amp fuse. No noticed mileage improvement, and a DRL light popped up on the dash, which I can ignore.

The next mod was a grill block, thanks to inspiration from Istas I decided to try to make both upper and lower blocks. The upper block was a failure because I accidentally cut it too short and tried to expose the Honda badge. I have a whole other sheet of brand spankiní new coroplast, but I didnít want to cut into it in case I wanted to do a belly pan. The lower block however was a success and I think it looks decent. I thought about putting the hole in the middle, but I wanted to have cooling air going to the A/C evaporator to retain full A/C performance should I need it. The block is attached with six strips of Velcro on each surface: 2 long strips, top and bottom, and little strips on each side of them. The grill block did not raise the operating temperature and I did not notice any mileage improvement either.

After that I remembered the stupid little glovebox light that turns on whenever the headlights are on, so in the interest of reducing electrical load, I took it out.

Planned mods: Wheel covers, Rear wheel skirts, Engine and rear undertray, Hybrid diffuser if i can find one for cheap, airdam, and upper grill block.
