Secret vacuum line to save mpg
My cousin was on the mnt and he said a guy did something to one of his vacuum lines on his jeep which let him get like 30mpg? Has anyone heard about this or know how?

ive always just took that tube coming out of the top of my engine and put about 3 cups of salt water in it. helps to maximize power at mid rpm's. im getting about 25 mpg around town and close to 32 on free ways...

I heard from a friend of a friend of a friend that if you can increase the vaccum to the flux capacitor you can get those types of mileage figures. Maybe that was the mod your friend was talking about.
My friends, friends, friend seemed to be on the level, so I'm sure it works.

Just remember to flush out your engine with clean water and let water flow through while you have it running for 10 minutes EVERY time you change your oil. Since water an oil don't mix, the water will only remove any contaminants and the small amount of oil that doesn't drain will continue lubricating. When adding the new oil, remember to mix in 1/8 cup of gasoline (premium grade) for every quart of oil (1.5 cups for 6 qts)
Also, for increased HP just pour a 16 oz NOS energy drink(original flavor ONLY) into the gas tank when you fill up

Your cousin is correct. Some have reported up to 40 mpg just by moving the vacuum line. But since you aren't part of the inner circle, we'd have to kill you if we told you.
