I've decided to get the Soy Shield and worry about the ant-gel next Fall.I've heard they blend in kerosene to lower the gel point but I think an anti-gel would give more bank for the buck.Here's some of the data sheet for Soy Shield,it also looks like it might have some anti fungal benefits and stabilizes the fuel.
SoyShield contains a unique blend of methyl soyate bio-diesel derived from soybean oil and a highly concentrated multi-functional additive package. When used at the recommended treatment rate, this unique combination allows SoyShield to provide the following performance benefits.
1. Supports the use of a renewable farmer-supplied fuel source.
2. Boosts the fuel's cetane rating up to 3 to 4 points.
3. Faster warm-up.
4. Reduced misfiring at lower air inlet temperatures.
5. Superior Cummins L-10 and N-14 performance.
6. Detergency to provide cleanliness throughout the entire fuel system.
7. Clean up and Keep clean performance for the entire fuel system.
8. Improved combustion of the fuel by completely vaporizing the fuel into smaller particles, thus providing better fuel economy and preventing a significant loss in engine power.
9. Increased fuel economy up to 5% - 7%.
10. Up to 5% improvement in Horsepower.
11. Dispersion of insoluble gums and varnish present in low quality fuels.
12. Modification of existing injector deposits, allowing for their removal and safe passage into the combustion chamber where they can be burned.
13.Reduced emissions, exhaust smoke and particulates.
14.A reduction in black smoke.
15.Increased fuel lubricity. (Soy based bio-diesel has 3 times the lubricity of diesel fuel).
16.Excellent anti-wear protection for the injectors and the fuel pump especially for those engines burning low sulfur diesel fuel.
17. Lubrication of the upper cylinders, fuel pumps and injectors.
18. Supplemental ring and valve-train anti-wear protection.
19. Increased thermal stability to the diesel fuel in order to provide the ability to resist thermal degradation.
20. Inhibition of oxidation during storage.
21. Extended storage stability.
22. Helps control the acidic by-products produced by the combustion of diesel fuel.
23. Rust and corrosion protection to the entire fuel system.
24. Dispersion of water present in diesel fuel in order to prevent fuel icing and other problems associated with water.
25. Prevention of the formation of stable fuel-water emulsions.
26. Allows moisture to be rapidly separated from the fuel.
27. Allows the diesel fuel to meet the NCWM's Premium Diesel Fuel Specifications.
28. Helps control the conditions that lead to fool smelling fuel, stringiness and plugged filters.
Also it helps the soybean growers out or at least gives them another market,to bad they can't think of a way to use milk as a renewable fuel or as an additive,that would help me out
