You are still doing better than most who do nothing. At least you have learned some techniques, and I bet you still use them even when driving aggressively. I know I do. I never seem to drive fast up to a red light anymore. You also have an efficient car. There are many here where I live who drive super large SUV's and dwarf my little civic in traffic. But i often tipple their mileage.

Just plain ol' put it in neutral and let out the clutch. Part of it is P&G and part of it is down hill. Although, like I mentioned earlier, the difference works out to about 1 mpg.

As for tire pressures my g/f doesn't care for pressures higher than 37psi. It's not a comfortable ride and I WILL hear about it every time she drives it :(. She's happy the way it is and so am I :)

If you pump up tires over the recommended pressures, you must monitor those pressures carefully. A 51 PSI cold tire pressure at sub-50 degree temperatures on a western Washington morning in the shade, can be sky high on a 111 degree eastern Washington afternoon in the sun driving 75 MPH with a heavy load.

Without carefully advising people such, your instructions are dangerous & people must ignore your post.

yes usually those senior cars have alot of carbon buildup cuz they dont floor it to blast the cobwebs out so to speak...

heck my grandpa has 1996 f-150 with 15K miles on it...hasnt been driven the last few months...(possibly year?) he cant see and my grandma cant climb up in it so it rarely ever gets driven...

Everyone should check their pressure once per week, either way; but the excess pressure from ambient temperature isn't much, and the increase in cold pressure means that the tire won't heat up anywhere near as much from the high speed/heavy load. In fact, if you're going to run high speeds and heavy loads, you're supposed to increase your tire pressure, sometimes beyond the tire manufacturer's maximum cold pressure rating. See https://www.tirerack.com/tires/tirete....jsp?techid=72 (titled "Air Pressure/Load Adjustment for High Speed Driving") for example; in a part about driving on the Autobahn, it says:
That means that tires are safe when overinflated even beyond their stamped maximum, though I still don't support exceeding that number in the US for insurance/liability reasons. Just the same, there's no need for fear when increasing inflation.

Like I said, I don't recommend exceeding the maximum pressure rating; but I know it is safe to do, probably up to 200% or more of the rating (that's an educated guess). You will feel the uncomfortable ride and bouncy handling LONG before you risk tire failure, which would most likely happen in the form of the tire bead coming unseated from the rim.

thisisntjared's suggestion of "try 44-51psi. 37 really isnt much at all..." cannot possibly be dangerous on any common modern US-market automobile.

For more links and information on common tire pressure concerns, see the tire pressure link in my sig.

i never do that because i think its too annoying. but if you are leaving the car on you are better off leaving it in gear for fuel economy.who is dumb enough to not accommodate for taking off a few psi for filling tires when they are cold?

anyway most new car tires that are worth something have a max psi of 44 or 51. and lets be perfectly clear about this, i am talking about the max pressure on the sidewall of the tire, because the car manufacturer gives a recommended psi that is based on compromise not fuel economy.

i dont think anybody would ignore my posts because of bad advice. if anything they would work to seek truth or correct me. your response is a case in point.

EDIT: i didnt notice theholycow already backed me up. :thumbup:
