It is great stuff, and it really pisses the neighbors off.

This is very interesting thread. Good job on logging the mileage LT2004ever.
Just a little input.
I have 01 civic LX Auto. I run Mobil 1 full synthetic oil with K&N oil filter. Plus It has drop in K&N air filter. Everything else is stock. Plugs have been changed to OEM plugs 3K miles ago.
I drive to work about 25 miles each way over two mountains. My average gas mileage is around 30mpg. I never got lower than 30 and that is with rpm staying in 4K+ going uphill all the time.
Can't wait to see numbers with acetone runs.

SO the total, for just "grounding kit, cut off at idle, weight reduction, STP System Cleaner

Average 2 = 31.135MPG




Now, Due to recent discussions with friends, i have decided to do the acetone after i do the spark plug run. Just because if there is a increase or a decrease i can say it was just the acetone or what not. So yeah heres the first few spark plug updates.

Well I thought that these pics would go good here.

I went 427.3 miles on just short of 11 gallons of gas.
That is 39.067 miles per gallon. Not bad when I avg over 80 mph.

Here are the pics. Also this will help those that want to know how far they can drive with the lite on. I went about 75 miles. Just look at my gas gauge. It did not move when I turned the car off. It was past the corner of the "E". I also took some pics with the tach in them, just to prove the car was running when I took the pics.

I think people often forget that having poor alignment can really hurt your gas mileage. My car had been pulling to one side for quite some time. After getting an alignment, I saw a significant increase in gas mileage.

hehe last time i went to chatt, i averaged about 44 the way up there and maybe higher the way back, cause i wad going downhill the whole way. But yea 77 is my cars sweet spot! oh yea i have like a ton of updates sitting in my car. I have all the old receipts with all the info on them. Like with the sparks, it went down once, just slightly. N e wayz, when i drive back home this weekend i will finish the sparks test and move on to acetone.

Also as for alignments, yea they do help! but i get my car aligned every time i get a balance and rotate

Well since LT has not updated this, here is a post just to help out.

This is an email I received the other day. We (the company I work for) was looking for a consultant with regards to our fleet of truck and trying to decrease the fuel bills...aren't we all.


I've been in petroleum pipeline business for about 31 years, currently working for the Kinder-Morgan Pipeline here in San Jose , CA .. We deliver about 4 million gallons in a 24-hour period from the pipe line; one day it's diesel, the next day it's jet fuel and gasoline. We have 34 storage tanks here with a total capacity of 16,800,000 gallons. Here are some tricks to help you get your money's worth:


1. Fill up your car or truck in the morning when the temperature is still cool. Remember that all service stations have their storage tanks buried below ground; and the colder the ground, the denser the gasoline. When it gets warmer gasoline expands, so if you're filling up in the afternoon or in the evening, what should be a gallon is not exactly a gallon. In the petroleum business, the specific gravity and temperature of the fuel (gasoline, diesel, jet fuel, ethanol and other petroleum products) are significant. Every truckload that we load is temperature-compensated so that the indicated gallonage is actually the amount pumped. A one-degree rise in temperature is a big deal for businesses, but service stations don't have temperature compensation at their pumps.


2. If a tanker truck is filling the station's tank at the time you want to buy gas, do not fill up; most likely dirt and sludge in the tank is being stirred up when gas is being delivered, and you might be transferring that dirt from the bottom of their tank into your car's tank.


3. Fill up when your gas tank is half-full (or half-empty), because the more gas you have in your tank the less air there is and gasoline evaporates rapidly, especially when it's warm. (Gasoline storage tanks have an internal floating 'roof' membrane to act as a barrier between the gas and the atmosphere, thereby minimizing evaporation.)


4. If you look at the trigger you'll see that it has three delivery settings: slow, medium and high. When you're filling up do not squeeze the trigger of the nozzle to the high setting. You should be pumping at the slow setting, thereby minimizing vapors created while you are pumping. Hoses at the pump are corrugated; the corrugations act as a return path for vapor recovery from gas that already has been metered. If you are pumping at the high setting, the agitated gasoline contains more vapor, which is being sucked back into the underground tank, so you're getting less gas for your money. Hope this will help ease your 'pain at the pump'

Yea i know i havent updated in a while. All the reciepts are sitting back in my car. Gah, also i havent been driving as much lately, and the next time i do imma get an oil change.

oh yeah about this one
"3. Fill up when your gas tank is half-full (or half-empty), because the more gas you have in your tank the less air there is and gasoline evaporates rapidly, especially when it's warm.

What about the weight of your vehicle... with a full tank you are carrying
1 gallon = 8.66 lbs
so at 12 gallons u are luggin around 103lbs, lol and i remover like only 40 or so lbs, with my spare and extra stuff and got a increase in mileage. Dude at like a quarter of a tank my car feels so light, its awesome!
