Scenario: You park your car at Pep Boys but forget your wallet and go back to the car to get it. Its locked......so you unlock it, get your wallet , and then lock the car again. All this without running the car or starting it to recharge the engine vacuum.
While in Pep Boys, you notice you forgot the part u are trying to match, so you go out into the parking lot ONCE MORE and unlock/lock the car.
How many times can you do this without starting the car to recharge your vacuum tank?
All I can manage is 1.7 (sometimes 1, sometimes 2). Can anyone do better? Does anyone remember what their new car did? In a perfectlly sealed vacuum system, u should be able to do this infinite times...
