A while back I owned a motorhome with a big Ford 460 engine (with 4bbl
carb) that burned regular octane gasoline. I would always store the
motorhome in a barn over the winter (November -> April). A mechanic once
told me to fill the fuel tank to the top with high octane gasoline on my
last fillup before storing it. Every spring that old 460 started up just
like it was run yesterday.
After my last trip I stored the motor home for about thirty months before
selling it. Again it started right up without a hitch (after thirty
months). The new owner drove it away with a tank full of three year old gas.
According to that mechanic, as gas ages, the octane rating decreases so
storing a vehicle filled with high octane gasoline gives the gas some room
to age and still be useful. I believe the product Stabil 'stabilizes' the
octane.
Additionally filling the tank completely helps reduce water condensation.
I also use high octane gas in my lawn mower and my oil-mix weed trimmer and
chain saw. I leave the gas in the tanks all year long. Some times the
oil-mix gas is used over two or more years (depending on how many trees get
knocked down over my driveway by wind and ice).
