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.
