some peoples minds just wont let them grasp certian concepts.

Your car only uses fuel on the piston down stroke. If your engine is doing 10,000 rpms you have that many explosions in the cylinder and if you car is doing 5000 rpms you have less explosions and you use less gas.


So if your in first gear and doing 10,000 rpms at 30 mph your using more fuel than if your in over drive doing 3500 rpms at 70 mph....


Air, in a closed room circulates because of heating and cooling... hot air rises. cool air falls....

brake fluid circulates, all be it slight, it circulates. because of compression and heating and cooling.... thats why your brake fluid is brown all over.

access your skill level... ???
If I wanted to change my brake fluid I would go out and loosen all 4 nipples and push the brake pedal....I would fill it up 3 or 4 times and push it again and again.....then i would bleed the brakes the old fashioned way and go about my business...there is a new brake fluid out that is 40 dollars a bottle your probably ought to go get that stuff....
