This is FYI hearsay, something I read on this list (I think).

Mis Grade fuel is a marketing ploy to help fuel companies get rid of a strange product. If I recall all the details correctly, There are only three fuels pumped by refineries and large pumping outlets to regional distribution "tank farms": regular gas, which is then branded and additive packages added by various oil companies; high octane, which is then branded and additive packages added by various oil companies; and Amoco Ultimate which is special, and the pumping pipes and tanks go through special "cleansing flow" to make sure it is pure.

Mid grade is the swill that comes out of the pipe when they switch from regular to high octane or vice versa, and the gas is mixed. For marketing reasons, they can't throw it away, so they sell it a "mid grade". The octane varies widely.

<< File: ATT00001.htm >> I run Mid Grade Gas in my 84 Westfalia. Runs horrible on reg. and lousy mileage, On high test it makes no differance than the mid grade for the Van, No hard facts, but I have put 100,000 miles on my Westy in the last 4.5 years and it works for me.
