ya the short ram. the cold air doesn't fit autos and dangerous anyway with water.

it really doesnt matter too much if you add an intake and add moderatly sized wheels (15-17 inches) becuase driving for 20 miles at a gentler pace will offset any difference from those mods. the best way to save gas is to use less of it yourself. mods dont affect that much unless you add something like a turbo or 10" wheels. even then drive normal and you should be ok!

Here's a thought: If you have any K & N type filter (AEM, and many others) with wire mesh and cotton inside, use the K & N recharger kit. I'd say to do it at bare minimum once a year. These filters get feelthy over time, and you could be undoing whatever benefit you got from your intake in the first place.

does switching from plus or premiun to regular actually help? doesnt regular ruin your car? jw ty

na it doesnt do anything for our cars, our car is designed for regular gas and thats what you should be putting in, you wont get any power gains or notice any difference if you put in premium

thats correct, listen to him. no power gains for higher octane and car will work same on either

when i ran premium i got 20mpg vs regular at 40mpg

-the radio is run off you battery, its independent of the motor so it doesn't affect your engine.

-Fuel cleaner will show minimal gains if any unless your car has massive gunkage in which case you should get a tuneup.

-Increasing tire pressure moves the wear around, it doesn't decrease it. Increasing the pressure moves wear to the center of the tire, and most cars suggest running the psi at @ 32 anyways. Check on your tire for the max pressure but you should be fine running at 40psi. The idea behind this is that the increased pressure stiffens up the tire decreasing rolling resistance but also decreasing traction and handling.

-Hybrids get away with shutting off the engine at stops because they use an electric motor to get moving. When they go to "start" the motor all they have to do is add fuel and spark as the gas engine is already being turned over by the wheels which are/were turned over by the electric motor.

-Gassing up in the morning or evening will not get you "denser" fuel. The gas is stored in underground tanks and as anyone will tell you the temperature in the ground is much more constant than the air above it, therefore you will see little if any fluctuation in gasoline temperature.

Also, most cars nowadays cut fuel when the car is engine braking. If you just leave it in gear coasting down a hill there's no need to shut off the engine as the computer has already stopped delivering fuel to the engine for you.

why is it i get only 23-25mpg? my mods are only aem v2 and magnaflow exhaust and 17" wheels, i drive most on freeways and at most 60-80 miles

get some lubecontrol.com products to raise mpg alot.

Can you explain how you coast in gear, my car doesn't do it.

Any electrical equipment will run off the battery but there is one other thing. If you put load on the battery the car will work the alternator a bit harder to recharge that battery. To get the best gas mileage is to not use a single electric item in the car except for the neccessary items.

The engine is not directly affected by the radio being on, but it is affected by how much strain is put on the alternator. More strain on battery, more strain on alternator.

Why would'nt the cleaner make noticable gains?

Are you saying that the starter could burn up?

I thought that one of the main reasons to fill up when it is cold out is because less gas will evaporate, but I am not sure.

"During closed throttle deceleration periods from moderate to high engine speeds. fuel delivery is not necessary or desirable. To prevent excessive decel emissions and improve fuel economy, the ECM will not open the injectors under certain decel conditions. The ECM will resume fuel injection at a calculated RPM.

Referring to the graph, fuel cut-off and resumption speeds are variable depending on coolant temperature, A/C clutch status, and STA signal. Essentially, when extra engine loads are present, the ECM will begin fuel injection earlier.

Fuel Tau Cut is a mode employed on some engines during long deceleration time with the throttle valve closed. during these times, excess oxygen would enter the catalytic converter. To prevent this, the ECM will very briefly pulse the injectors."

Found this in a toyota motor sales pdf. I have no idea what it is for, but it is interesting.
Also, read this its pretty strange. They put a fuel cut off switch on the shifter.

I think one of the best htings you can do is buy gas from a place that is not only always busy, but gets decent gas. The freestate in my area has shitty gas that make you get really low mpg. The freestate gets pretty good business, but not as good as mobil, where most people go because the gas really is better. My friends have all tested it, so has my mom. I have always wondered why, whether it is lower octane, dirty, or old, i do not know.
