Thanks for the reality check.
Over the years I have seen the following advice for gas savings:
Proper tire Inflation = 15%
Drive Speed Limit = 10%
Change Oil/Filter= 10%
Accelerate Smoothly = 15%
Coast to Stop = 15%
Use Freeways = 15%
Use Cruise Control = 10%
Install a Tornado = 22%
Use Chevron Gas = 3%
Total = 115%.
I did all this and every so many miles I would have to stop and let gas out of my tank.
I guess this law applies to my new found awesome gas mileage. Unfortunately, it proves that P&G won't work on my car because I have achieved better mileage by cruising at 55. I know it is capable of over 30 mpg and even dogging it, the lowest I have seen per tank is 24.5mpg.
