Must admit I too have been very sceptical about stale fuel but this exercise has proved it to me except for the compression issue. I have just done a compression test with a hot engine and throttle wide open and it's giving around from 80 to a max of almost 90. As I have previously said Ibelieve that maximum compression is the cars compression ratio times atmospheric pressure so the maximum I can expect with 6/1 ratio which my big seven is is 6x14.7 equals 88.7. Is their correct or not? If it is then no way can you get any higher readings than this so I am either wrong or there are some incorrect testers out there.
I recently bought a brand new compression tester and that gives a reading of 50 ish but an old one I borrowed gives my the 85 ish. Interesting!
