WHAT ARE SOME THINGS TO WATCH OUT FOR WHEN USING BIODIESEL?
Like all diesel fuel, biodiesel does not perform well at low temps. To combat this problem mix in more normal diesel during cold weather. If you are running b20 (20% biodiesel 80% diesel) you shouldn’t see any performance differences than using normal diesel (while still reducing emissions and lowering co2 output). In very old engines that still use natural rubber gaskets or hoses these parts should be removed and replaced with synthetic ones, as biodiesel will eat them away. Due to biodiesel’s amazing solvent properties if you have a dirty engine and then run biodiesel through it it will clean all the gunk that has collected on your engine and you will need to change your fuel filter several times until it is all cleaned out. Also like normal diesel you shouldn’t use any biodiesel that is older than six months. Other than that it can be used like normal diesel.
