[AT] Gas problem now diesel

[Ron Cook]

Henry,
     I was using Power Service religiously all the time.  Following the 
directions to the tee.  I do mix my own winter blend of No. 2 nand No. 
1, so gelling is not a problem.  I stay local so my fuel generally comes 
from my own storage.  Starting, power, smoke, algae are all no problem 
here for me.  However the old 3406 mechanical just was not smooth.  You 
could feel it in the steering wheel at idle.  Then one day about 2 years 
ago I filled one tank with bio diesel and switched to that tank.  Holy 
Smokes!!!  NIce, smooth running 3406 just like 15 years ago.  So, the 
heck with the naysayers, I started using bio until cold weather.  I knew 
that would not work and it was back to Power Service.  Old engine 
returned to previous not smooth condition.  It has to be lubrication in 
the injection pump.  So.....everyone alway remarked about my nice smooth 
running Pratt & Whitney R1340.  My secret there was the use of MMO in 
the fuel and oil.  For sure in the fuel.  2 gallons to 1000 gal.  Boy, 
do I get alot of "looks" when I give out my secret. People just call it 
a snake oil solution and scoff at me.  But still, the old Pratt runs 
like an electric motor.  Plumb smooth.  In the Pratt, it has to do with 
the valves as it is a carbureted engine.  What many do not know is that 
the military used it by the millions of gallons during WWII to keep the 
radials running smooth on the various grades of fuel they had to use.  
It is not certified for use in aviation engines.  Interesting, eh?  
Well, I figured if it would smooth out the ole Pratt, it just might 
smooth out the Cat.  It did!!  Way more than Power Service.  And what it 
did that PS did not do was increase the fuel mileage enough that the MMO 
is free.  I mix it at the same rate in the diesel storage as the av gas 
storage.  Try it.  It will not work.  Just some old auto transmission 
fluid.  Seen it before.  Junk,  Snake oil.  Don't hollar at me!

Remember, the fuel is blended for the most profit for the use of the 
most customers.  Mostly newer electronically controlled injection.

There is on exception to this rule: biodiesel is an excelent lubrication, and so if they are blending biodiesel they automatically get much better lubrication.  Biodiesel is an expensive additive though, and so they never use it for lubrication, they use it either to meet legal requirements, or for environmental marketing.
