I wanted to ask at what mileage should i go have a tune up for my 01 corolla...i know i should have a service manual but i dont so please help me out...thnxz.
Also does lowering your car by any chance help increase your mpg?

i my self like to change my plugs about 30-40k miles. some go longer, some change sooner.
as for lowering, no it shouldnt affect you gas mileage by itself. it may affect how you drive your car which could use more gas.

Despite what the two above me said, I read you can improve gas mileage by lowering your vehicle, according to edmunds. But it varies on vehicle to vehicle on how much MPGs gained if at all.
My personal thinking is that high end cars are lower for a reason. To lower drag and improve aerodynamics, plus too it looks sleek. Altough correct me if I'm wrong on this.

higher end cars are lower mostly for the fact a lower center of gravity will improve high speed handling. they are designed to have a decently high coefficient of drag. the reason for this is to produce down force a high speeds to keep the car on the road. a great example of what happens to a high end car at high speeds with no down force is the koenigsegg ccxr when it was first tested on top gear. the stig couldn't even control it and wrecked it. here is the clip. :
now, a flat underside of a car has a greater impact on aerodynamics and drag than lowering a car will. plus if properly designed it will help to keep the car stable during high speed runs. this is because the air moving below the car is moving faster than the air above it. thus creating a low pressure area below the car. also when properly designed it will create less turbulence behind your car. this can increase mpg.

That's more of a theory. But it relates more to lowering the coefficient of drag to accomplish this.

Yes I know this, but when I said my previous post the high end cars I was talking about the regular commuter Benz, BMW's, Lexus sedans you see old people driving, not the higher sport models.

Right so for slower cars such as the Corolla, the lower Cd would help aerodynamics.
Now I'm not saying that lowering a Corolla is gonna increase your MPG's. I'm just saying, theory or fact, I read that lowering a car decreases the Cd and in turn would increases MPG's.

the corolla all ready has a low coefficient of drag. if i remember correctly it was .032 or .033. i remember for it being a 4 door sedan it has a unusually low drag coefficient. my s13's was .30 so its not to far off, if i am remembering correctly. it looks like toyota all ready thought of this when designing the car.

Ok I see now, so you're saying that our Corolla's Coefficent of drag can't go any lower?

no, it could go lower, but its low enough that any decrease will not yield any significant gains. plus will make the car worse to drive on the highway due to its lack of down force. it would be very very unstable while cornering.

Ah interesting. I've really been interested in aerodynamics lately after seeing DTM cars and learning a bit more about F1 cars. So I've been thinking how I can better optimize my Corolla's aerodymanics, wether it be for grip or just to increase MPG's, even if just a minute improvment.

the best way to increase its aerodynamics without ruining its high speed stability would be to lower it, and create a underbody panel kit. so its flat the whole lenght of the car, with cut outs for wheel wells/suspension movement, oil drain and filter access. then of course the rear with a built in diffuser to channel the air up and minimize turbulence behind the car. turbo mag did an article with this, although it was on a acura nsx-r it can still be applied to any car. just the results may not be as drastic.
