When I filled up for the tank prior to the one I'm about to finish now, I found that it was extremely easy to keep the FCD maxed out at 150+ on the 8+ mile trip home from the station; sometimes even under light acceleration. In fact, when I got home, I switched the display to metric and did the conversion math and it figured out to 158.8 mpg. I'm assuming it is due to the vapors present from the fill procedure being burned off. This has me wondering if there is some practical/safe way to duplicate this. I have seen some awesome feats attempted and most of them accomplished by some very brilliant members here and am wondering if somebody could put together some kind of a vapor chamber that could operate automatically or even manually?
