I recently purchased a 1973 Super beetle with a 1600 cc engine. Compression is fine and the engine runs good after a thorough tuneup. The car sat for a few months and only get's 15mpg. Causes?
I recently bought a 73 Super Beetle. After my mechanic did a thorough tune up and did a compression test the car runs fine. But after doing 2 averages on fuel vs.mileage I'm only getting 15 miles per gallon. Using unleaded fuel. The car had not been driven for several months. Could this be the reason my mileage is bad. I've owned 7 V.W.'s, several of them Super Beetles and usually get 24 to 28 m.p.g. Any thoughts one what could cause the low miles per gallon?
