I have been using b5 bio now for three tanks worth. Power seems the same and mpg is 15.35, hand calculated. This is the same as dino fuel. Anyone else with simular results?

 

You shouldn't notice any difference, mileage or power, at B5. Outstanding lubricity gain though even at that small amount. Once you get to B20 and up is when you will notice slight drop in mpg and power.

I am currently on B100 and average 14-15 mpg highway. A year ago when I ran straight #2 ULSD I hit 17mpg. These are with a heavy foot at average speed of 70mph.(3.73 axle ratio). So, around a 10-12% drop in mpg. Power feels about proportionately the same drop, maybe less.

I don't care though since I brew my own. With the recent drop in methanol prices my raw cost to make bio is less than $.90/gallon.

 

x2! Ive ran a few tanks at B100 and it wasnt too much difference in MPG. I too brew my own, but not enough anymore to run B100. I run maybe a B10-20 blend now just for lubricity purposes. B5 isnt enough to really see noticeable changes IMO.

Alvin...do you have a business license and a local chemical manufacturer around?! Its been pretty valuable to me in my little bio venture!

 

I see just a small decrease in milleage too, nothing big max 2mpg loss.

 

I just traveled from OH to NE (800 miles) on my home brew of B100. My mileage, running @ around 70 mph with a 10 - 15 mph head wind was 18 (hand calculated, of course). Once I get to WY (today) I'll be filling up with straight petro, and I'll keep you posted on the results; as soon as I get out of the "boonies" and to a place with internet.

 

X2......

 

Tristan, Yes I do have a business license (unrelated business BTW), but as far as chemical manufacturers, none. We have distributors such as Tarr Inc. and Univar. Luckily there's a handful of homebrew hobbyists here that get together and bulk buy drums of methanol. Last drum I bought was $160. So at .64/gallon in methanol cost per batch, I'm pretty happy.

I too, am a huge advocate of running bio in our rigs at any percentage. Plenty of studies and reports out there that support the lubricity advantage.

 

I buy all my NaOH and Meth from a chemical manufacturer 15 minutes from the house. They even deliver the methanol to my "place of business" since the look down on shipping to houses around these parts!

They are only distributors of methanol but they do process and manufacture a lot of bad caustic stuff there!

 

You're lucky to have that so close. BTW, I'm noticing most all of you have tuners. I'm jealous. Still need to do the gauges and 4" exhaust first. Can't wait to wake up my 7.3 on B100!

 

Youve got Clay up there pretty close to ya! He can hook you up on exhaust, gauges, and a DP Tuner...

Hes got a deal for like 283 shipped on new 4" turbo back MBRP exhaust right now.

 

Great exhaust system for the money too! Just picked up one for my dad's Cummins from Clay.

 

so i noticed some yall are runnin b100. i have been reading about biodiesel all day long. i have read it affects some of the o rings and seals and hoses. so has anyone had any problems out of running b100 and what if any modifications have yall done to your rigs. o and one last question where did yall get your homebrew kits from im not wantin to spend goo gobs of dough

 

Your superduty has all the necessary bio-compatible o-rings, seals, and hoses. The only thing you might need to look out for is when you first run biodiesel is it's amazing solvent qualities. It will clean out any build up in your fuel tank and possibly clog your fuel filter. No problem though, just carry a spare if it does happen. Didn't happen to me though since I figure my tank was pretty clean to start out with.

I made my own processor and wash tank out of 55 gallon drums, black pipe, a bunch of 3/4 ball valves, cheap harbor freight pump, water heater elements and wiring. I probably spent around $300, plus parts I had laying around. Plenty of info out there, but first thing to do is to secure your supply of waste oil from restaurants. Without that your dead in the water.

 

Words to live by in bio processing.

 

I have 3 or 4 mexican restaurants that I deal with, I have even been willing to share oil if they will pick it up. Last year I needed to clear out my shed and gave away around 20 5 gallon pails of used veg oil.
