Gary has been experimenting with WVO on his Isuzu P'up(1982 Chevy Luv 2wd short bed diesel).  He's used and documented testing with a number of WVO Design's parts along with others.   His Forum is well populated with is photos, testing results and discussions.  He's currently working on a project to swap a diesel engine into his Trooper.  Sweet!

Gary also has an interesting oil processing procedure he explained to me:

My process is a little different than most.  I don't rely on the centrifuge for de-watering.  I use a heated recirculation process using a monster gear pump, 2000 Watt heater in a 50 gallon steel drum, a WVO Designs 1000 Watt in-line heater just after the gear pump and a Utah Bio-diesel drying head.  I blow in dry air from a 1000 watt heater into the 50 gallon drying drum and exhaust out the humid air using an exhaust fan.  I typically dry the oil for 4 hours in the winter and 3 hours in the warmer

You asked, so we designed and built a replacement for the faulty Fass and under-performing BFT Scorpion pumps. The latest results suggest we have worked out the kinks and successfully designed a way to integrate our superior WVO pump into a Vegistroke and Ramstroke system. Yes folks, we've had success on the Ramstroke as well. There is a discussion in our forum.

After an unsuccessful attempt with 3 used transmissions, I finally got a rebuilt one from Sun Valley Mercedes.   They happened to need a centrifuge to clean up their used tranny oil, so it all worked out.  I'm expecting the best from this rebuilt one.   My local German vintage mercedes mechanic, Garrett, is putting it in now.   He's not from the motherland, but he does speak German, so that counts for something.

My used tranny foray was quite a mental, emotional and time suck.   My original transmission worked OK, with a slip between 2nd and 3rd.  It got progressively worse and would  barely go into 3rd gear.  We tried all sorts of vacuum adjustments, boden cable ajustments, k1 spring replacement, b2 piston replacment, prayer and few bottles of trans x.  I've heard that used ones work and gave it a shot.  They are only $99 at pick and pull.   In the end, I spent hours of time and frustration with getting the used ones working rig

US Diesel prices have dipped recently.  Here are some historical graphs for your perusal.

That's right, you can now use a gas motor to pump veggie oil with speed and ease using our industry leading Monster Pump Heads, a custom fabricated adapter plate and gas motor.    WVO Design's Electric Motors work well, however some folks don't have access to AC power at the collection site.    This has been on our design list for a while.  Alas, someone has beat us to the PUNCH and our friend Graydon at Utah biodiesel is now offering the missing link.   Thanks to Graydon and his fabricator Chad, you can buy an adapter plate to fit our Raw Power  pump heads to a Harbor Freight motor.

Here is my 1987 300SDL.   I have a bunch of fun working on this thing and converting it to WVO.  I'm going to start sharing my adventures on this blog.   We'll start today with the Raw Power Fuel Pump I added to my fuel system.  I added a pressure gauge before my filter and  was only seeing and average of 8 psi out of my stock lift pump.  Spec lift pressure for this injection pump is 11-17 PSI.  Thus I wanted to see if I could get more power by boosting the pressure up to spec.   I currently run a single tank setup, so I bypassed my stock lift pump.  I filled it with motor oil and put a hose on it to loop motor oil so the veggie oil that was in there doesn't polymerize.  I want to keep it in good working order in case I need it.

So I added the pump yesterday, Memorial Day.  I also swapped out a FPHE for an old heat exchanger.   I tried out this black steel exchanger and it worked well.  The FPHE works bett

I recently took a trip to Atlanta to our distribution center and thought it was time to provide our customers an insight into our operations and fulfillment system.  For the past couple years we have been using a professional fulfillment service to pick, pack and ship our orders as well as storing our inventory.  Using professional distribution allows us to ship most orders within 24hrs.   We at  WVO Designs can then focus on our core strengths; designing the best WVO products and providing fanatical customer service.

My visit to the facility corresponded with planned changes to the organization of our 100s of parts, along with our software systems which will result in improving our speed, accuracy and efficiency.   I was also  impressed with

That's a glimpse into my local veggie co-op.   To some, the term "co-op" inaccurately describes a group where one person does all the work.   Fortunately with our group,  the term co-op accurately describes how we function.  Not everyone does the exact same amount of work, but no one is working too hard and there has always been oil ready.   Someone always knows when to pitch in and help when there is work to do.  A responsibility many of us don't learn until much later in life.

We keep a running tab of how much oil each individual brings in, and that is how much they can take out.  There are 3 of us.  Until someone has a significant interest in joining(and a  potential contribution to offer), we offer people clean oil in trade for dirty.  We take 50%  of the oil that we clean.  This 50% arragement  has been a mutually advantageous system I've used for years.

The process is simple.   We collect our oil from local restaurants in the 5 gallon cubies.  We then settle the oil i

Wade Mahoney from Sunsational Oils sent us some of his Sunflower Cooking oil as a thankyou for providing him with a Beast Centrifuge that he modified to be food grade. He grows, harvests and presses his sunflowers at his farm in Ohio. He then lets the oil settle for a few days before running it through the centrifuge to clarify/de-gum the oil. We this it looks and tastes great!

The most widely discussed and important variable with running waste oil is temperature.    With the change in season comes some rather significant changes in temperature.  The significant change will happen when temperatures drop below the cloud point of the vegetable oil.  Cloud point is when dissolved or "melted" solids in the oil, such as wax, begin to separate from the oil and solidify.   Cloud point is dependent on the type of oil.  With biodiesel, cloud point will vary on the type of oil used to product the biodiesel.  See the charts below as an example.  The information has been gleaned from the internet from some cursory research.
