Fuel Question...Age?

[Ihncheol Park]

I've been using Magnum fuels in quarts until now for the past 4 years.  All
were stored in shade, in the shipping carton.  Never had any problem even
from 2 years old fuel.

I just got a fresh batch of 3 cases Magnum DZ fuel.  They didn't come with
those red inner caps that come with Morgan's Coolpower.
So, I opened all the bottle, slightly push one side to level up the fuell to
the top of the bottle. Then, used saran wrap between the cap and the bottle.
If any air and moisture goes in the fuel bottle, I will know by the shape of
the bottle later on.

Also, it often takes more than a few weeks to finish a gallon of fuel, so I
began using Slimline fuel cap since early this year with one outlet plugged
with check valve, so that no air goes in to the fuel jug.  When I begin to
use a new gallon fuel, I take as much air out before putting on the cap.
So far, it kept my fuel fresh enough not to feel any difference.  Anybody
using it?

    I've used fuel that's been stored in the original shipping cartons for
5+ years with no problem. However, a few years ago Magnum had a batch of
jugs that would develop a small crack, usually near the top in the vapor
space, from flexing due to thermal expansion / contraction of the fuel.
Generally it's pretty obvious, as the jug is not full due to escaping
methanol. The remaining fuel is less volatile and can give varied
performance.

    The jug's "breathing" also admits moisture containing air, however
moisture is not as detrimental as some profess. (Consider the amount of
water in the 6 or so lbs of air the engine consumes per lb of fuel.)
Minimizing methanol's exposure to air both limits moisture incursion and
volatile matter excursion, both bad.
