Raider: a CAI won't give better gas mileage. More o2=more fuel to keep the A/F ratio correct = less MPG.

Basic maintanence is really all u can do, even if you make your engine more efficient through headers, exhaust, lightweight pulleys, etc you won't get more than maybe 1mpg more. Keeping your tires properly inflated, changing th oil as needed, etc etc etc though will keep ur cars mpg as high as possible

Get a factory repair manual if you can afford it. they're expensive and like 2000 pages. If you want to maintain it, get a Helms or Chilton book. $20 investment, and worth it for weekly maintenance.

Use the correct fluids. 10w40 oil and 5w30 oil have different compositions. Don't use generic fluids. Your TL is a Honda-built engine, and I've found that Honda specific fluids work best; even if they're more expensive.

Check your car weekly.

Check tire pressures. TLs are FWD (means front-engine, front wheel drive) and front and back sometimes have different pressures. Check around your diver side door frame for the label showing the correct pressures on stock wheels and factory recommended tires. If you're using after-market rims and tires, the proper load pressure is written on the tires themselves.

Check tread depth. On stock tires, take a penny (if you're in the US), and put it heads-side out upside down in a couple of the tread grooves. Inside, middle, and outside of the tire as you look at it. If the tread depth doesn't reach the top of Lincoln's head, time to replace the tires.

Check transmission fluid. Automatics have a dipstick under the hood labeled 'Transmission'. If the fluid is low or not a golden to light brown color, replace it. Usually about 7k-10k miles. Transmission gears do wear down, and junk can float around.

Check the air filter and change every time you change the oil. The filter keeps road junk out of the engine. If it gets buildup, air won't flow properly and you're choking the engine.

As for cheap addition to HP: additional parts are good in practice, but add wear to the engine. It's designed from the manufacturer to certain specs which are best for the vehicle. Use caution, or seek a professional tuner for the best known additions. After all, if the factory didn't install it, why not if it makes it better?

Take out any extra weight you don't need. You can also take out the interior pieces you don't need. I took out my rear seats, passenger seat, floor mats, and everything in the trunk. Saved about 100lbs. Car handles better and since i'm not carrying the extra weight my mpg went up about 2mpg.

17lbs = 1hp, so I gained almost 6hp from weight reduction. Your car wont make more power, but it will be able to use more of the power on the road, not moving the extra weight.

1.cold air intake: it does give you better gas mileage because its letting more air go in which makes your motor work less which saves gas.

2.program your ecu


4.synthetic oil

5,.high-flow cat
