i have been working on semis for ten years, when i first started hardly ever had a road call for gell ups, now within the last few years since bio fuel has been used more i get road calls for gell ups when its 20 to 30 outside, my buddy works at a bio plant and told me that stuff would start to wax at 40, i had to replace fuel lines many of times on semis because of the bio fuel eating them up, if it was so good why would the dealer care what percent of bio you use for war. reasons ? it also causes allergy to grow in you tank
You have a lot of research to do my friend. I'm not disagreeing with what you have seen first hand, but you need to understand that there is a lot of ways to use Bio WRONG. It happens way too often, and then the fuel is the first to be blamed because its easy. Hardly ever will a guy admit to doing something wrong, especially when it wrecks his most prized posession (his truck).
Bio and WVO can eat certain rubbers, so if it's a very old truck, yes it may damage fuel lines. Most newer trucks (6.0's included) shouldn't have this issue.
100% bio should not be run right away after a switch from #2, as already said it can be VERY cleansing and will clean all the varnish off of your tank inside and other parts it encounters. This is why it is recommended to start in small doses and work your way up to 100%. It is also recommended you change fuel filters very often when first introducing bio to your truck.
Yes it can and will gel easier, just the name of the game. You can avoid this by running a heated, two-tank setup like the vegistroke. Or just dont use it during the colder months, or dilute it, but this all depends where you live. Up where I live here in upstate NY, using bio during the winter is generally not a good idea unless the heated tank approach is used. A lot of times, waxing will depend on the quality of the bio being produced too.
WVO in itself has less energy density than #2 as already stated, but on the other hand it is also very lubricative. This is a pretty fair trade off and can also negate the negative effect of less energy. The quality of the WVO (your base oil in which the bio is produced from) will also play a HUGE role in how the end product works. When not filtered properly, the suspended fats and water molecules in the WVO can eat and destroy everything in your fuel system over a period of time.
As of right now, in most places, buying bio at the pump really wont save any money, but it can be beneficial for your trucks life and the environment (like most of the guys bellowing black smoke even care... haha). However if you do the research, test it, validate it, and manufacture this stuff on your own, it can be very rewarding and cost saving.
