+2 on that. (Although.... even modern diesel is a bit more problematic these days, IMO....).If it was something besides gasoline fueled once a year is probably fine.
If somebody has a practice that is working for them, consistent Results are what matters. Show Me - after that I prefer to understand why results differ among people.... that takes longer to figure out sometimes.....
I don't have the time/$/resources to do an actual controlled study, but glimpses I've had in this thread (and others) leads me to think that one factor with gasoline (on the storage/re-starting-fine front) is regional fuel formula differences. Smog or other additives being present at a regional refinery, or not, I can see as possibly being a prominent factor in how well storage works out for the end-user.
Even Jay Leno doesn't have the resources to operate two massive personal garages on opposite sides of the country, so I'm not expecting to test that ^ theory anytime soon .
