Default One eyed 180 Stat

I finally got around to removing the 180 stat that I installed last year.
I had drilled 4 - 3/32" holes in it and during the colder winter months, it would set of the SES light because the engine would fail to reach operating temperature during shorter trips. In the summer it maintained 180 F all of the time except in stop and go slow traffic and does not set off the SES light. I also noticed a slight drop in mileage.

This time I only drilled a single 3/32" hole in a 180 Jet Stat.
What I observed is that the engine now runs a little hotter, around 5-10 F more than before and is quicker to move up to 205 F when going up hills or in slow traffic.
I am also rewarded with an improvement of 1 mpg in city driving....16 mpg.
It warms up quite a bit quicker now which explains the fuel economy increase.

I'm going to leave it in and monitor it thru the cooler winter months.

Your gas mileage should definately be much better since you mostly take short drives where your car doesn't have time to warm up. It may also be better on the engine as it is not good for it to run really cold all the time. (like 150 degrees or less)

HUH??? He said his mileage went up to 16mpg, not that he has a 16 gallon tank. I believe they are around 18 gallons IIRC anyways.

I think I got it now. When I first glanced the way he wrote that made it seem like he improved 1mpg....so 16 miles total to the tank, my bad. I knew it didn't mean that he has 16 more mpg in addition to what he had before. I'm really tired as hell what can I say. But shouldn't you get more than 16mpg city driving anyway in a 2000?

Yes, you should, but it becomes extremely difficult when you like to play. You can drive like grandma for a whole week and keep it at 20mpg or better. However, every good launch, or quick passing maneuver seems to cost you about 1mpg on your average. If he is still getting 16mpg, then I would say that he is showing some restraint.

I mostly get about 22 with a lot of city driving...about 30 or so on long highway trips. I have set the DIC to current MPG and watched it drop to 1mpg on jack-rabbit starts.

I notice that I lose mpg when starting and take off. Example, yesterday morning, my car said taht I had 63 miles until empty. By the time I got to the babysitters (his babysitter is only 6 miles away), shut the car off dropped him off, started the car and took off I had 54 miles until empty. I drove 6 miles from the babysitters to work, when I left my car said I had only 40 mile until empty. Should my car lose so much fuel on start up? The 3 roads that I travel are all the same type of stopand go traffic usually (unless I hit allth e lights grren).

The computer will adapt to your driving style...You will notice that if you do a lot of intown the driving the estimated miles left is a lot lower than if your on the highway for a bit. The computer will anticipate your usage of gas based on your previous few miles of driving. A full tank of gas will show up as about 250 miles to the tank for town driving yet climb to about 500 for highway driving.
