Looking at either this:
85 Plus
Designed for use in all diesel engines. Contains extremely powerful lubricants, detergents, seal conditioners, fuel stabilizers and rust preventatives, but without smoke suppressant. Red Line 85 Plus contains additional cetane improvers which boost the fuel 5-9 cetane numbers and additional lubricants which reduce wear in low sulfur fuel by 75%.
This improvement in lubricity and cetane will reduce detonation, assist starting, help reduce smoking, help prevent fuel system wear and leakage and can provide 5% additional power and efficiency.
This diesel fuel additive complies with the federal low sulfur content requirements for use in diesel motor vehicles and nonroad engines.
OR
Diesel Fuel Catalyst
Contains powerful high temperature detergents, lubricants and a combustion catalyst. This catalyst reduces smoke dramatically, reduces detonation, and improves fuel economy 4-8% based on fleet and dyno tests. The lubricants can reduce wear in low sulfur fuel by 75%, prolonging injector and fuel pump life. Corrosion inhibitors will help prevent rust and corrosion.
This diesel fuel additive complies with the federal low sulfur content requirements for use in diesel motor vehicles and nonroad engines.
Looking at a group buy on one of those, whichever I could get. Price should be <$45.
Let me hear your ideas on this....
