Decalin Chemicals: RunUp Fuel Additive
Actually, I did, Todd. They guy sent
me a complimentary spot of the stuff. I flew with it for over 20 hours and
it not only did not help but actually seemed to leave more deposits. In
the end after some research on the topic, I came to the conclusion that the
temperatures did not go high enough to cause the chemical reaction that bound
the lead. In other words, it would work with the high temperatures reached
in air cooled cylinder heads but apparently not with the lower temp water cooled
blocks. At least, that was my conclusion.
One of these days, I am going to find a
heavy duty ultrasonic cleaner and see if that might "buzz" the lead deposit off
the ceramic (without pulverizing the ceramic). Typical abrasive blasting
does not work very well due to the shrouding effect of the multiple ground
electrodes which tend to shield the ceramic cone.
Thanks for bring it to my
attention
Ed

Hi
Ed;
I recall a few years ago you were trying a few witch's potions in your
quest to remove lead from your plugs. Did you ever try this
stuff?

Decalin
RunUp™ Fuel Additive in a 16 or 32 ounce bottle, use at 1/2
oz per 10 gallons fuel.

rough running due to plug fouling
- Upgraded
formulation to combat combustion chamber deposits.
- Prevents valve
seat erosion from valve seat micro welding.
- Does not contain
volatile solvents so it is safe to ship and safe in the
cockpit. You can carry it with you for out-of-town
airports.
- Easy to use
graduated measuring and dispensing reservoir built into the
bottle. No messy syringes!
- Tested and stable
down to 0 degrees F.

Decalin RunUp is not approved for use in the
engines of certified aircraft but it has the same active ingredient,
Tri Cresyl
Phosphate as our previous product. Lycoming
clone users have reported very good results when using this
product.
Notes on using Decalin RunUp
:
Some white deposits may be seen on the plugs and
in the exhaust pipe during use; this is normal with RunUp since the lead
in the fuel is being converted to non conductive lead phosphate.
When no additive is used, lead oxide is formed. It is lead oxide
which causes plugs to misfire due to its partial conductivity shorting
out the plug. In addition, lead oxide tends to form in large
clumps or clinkers whereas the lead phosphate is crumbly and if any is
left behind in the combustion chamber it deposits in even layers.
Make sure you remove and clean your oxygen
sensor every 20 hours to remove these lead phosphate deposits when using
Decalin RunUp.
The dosage of 1/2 ounce per ten gallons of fuel
is a minimum. This can be increased to a maximum of 2 ounces per
gallon for problem engines. |
