650 miles on wvo... straight....one tank:D

I currently mix %50 WVO and diesel with no conversion to the vehicle. I plan on increasing the % WVO, add a electric filter heater and a pad heater under the pump to nozzle lines. Eventually I hope to have a small WVO tank under the hood. Heating this 4 gallon tank to engine temp is not a big issue. 4 gallons will get me to most of my trips and a reserve WVO jug in the trunk will get me home.
This is a 'best of both worlds' compromise. Diesel in the main tank, cut with WVO as weather permits and WVO for cruising.
Note I live in the great white north and do not plan on burning WVO in the MB durring salt weather. Hell I'll drive the Ford in salt!
As my system now stands including storage and filteration and $3 per gallon dino $, my payback is two years mostly because I don't drive very much.
Another posibility is cut WVO in the main tank and a small under the hood diesel tank. If just used for starting and purge (shut off), 2-4 gallons of dino could go a long way!

that's nice. If you check and recordyour compression now, and then run another 65,000 miles andf check it again, your results will be relevant.

when the thread started I decided to start recording miles..
right now its at about 2800 just becasue i just started keeping track
does not negate the fact that i only run on waist oil... and using your
illistration if it went 65000 miles before i had to replace the engine I would
consider it a success.


Look at the cost savings... it cost .12 cents a miles to drive on diesel so by driving your 65k miles the cost or savings in my case since i use only wvo is 7800 dollars... I would go to the junk yard and buy another engine for 1000 dollars and continue driving. So 65k miles is much better longevity then say compared to a 1982 buick which was designed to go 50k miles.

I would be totally satisified replacing an engine every 65k miles as a result of using veggie oil.... I would rather do that then to send my money to the middle east.

I don't even wanna know what "waist oil" is. ;) :D

Although it wasn't a Mercedes, I ran over 95,000 miles with my '80 Audi 4000 diesel on a two tank conversion running on 100%WVO (soy mostly) and starting on either 20%Kero/80%WVO or 15%RUG/85%WVO.

Durring that time, I only put diesel in the tank 3 times (the return legs of a couple of vacations).

interesting. Over what time period was this, how many years? Also, was this in NY or down south? What was the lowest temps that this fuel saw?

That sounds really irresponsible to me, not to mention impractical. 65K miles comes up for me every 4 years, and I would hate to have to source an engine. Who knows what the availability will be?

And if you really want to look at the economics of it, brewing biodiesel costs $0.65 a gallon, and it will not contribute to your engine's wear at all. So after saving $1000 a year, and not having to buy new engines every four, I get way ahead of that game.

I know this is a WVO miles thread, but I have 20K miles on my 240D burning B100.

BlueRanger may really be onto something here. Just replace your engine when the rings are coked and the crankcase oil has polymerized after running unheated WVO. Why didn't I think of that before going through the trouble of researching, reading scientific studies, designing a proper two tank system and then installing it? I mean logic and reason aside, there must just be a limitless amount of OM616 engines around that I could just throw into the car every time I destroy one with whatever oil based fuel I decide to pour in the tank and cold start on. I think next I will try oil based paint.

It really is amazing what you read on the internet.

Greasy benz has a good point with Elsbett. They have been running cold vegetable oil for almost 30yrs. They have driven the miles.

If the glow plugs stay on for a period of time after starts cold oil never hits the combustion chamber. Also Elsbett installs different injector nozzles to spray the oil properly.

So far I have 10k on WVO which is mainly canola oil and some soy. This is in my 99 which has the Elsbett single tank kit. I have started up on 100% cold oil in 22F weather and drove 30 minutes home.

I also use K100 in every tankfull to keep things clean.

To answer an earlier question, I have cleaned the injectors once on Strider, about 17,000 miles ago. I also have cleaned Penelope's once. I've been waiting for starting/running issues, but don't have any yet.

"You fortunately live in a place that doesn't see extremely low temperatures. RUG will separate from WVO at or below freezing. That'd really suck to gulp a slug of separated RUG before your filter plugs from solidifying WVO."

This is not true. I ran my car through the entire DC winter at temps in the upper teens. There is no separation, ever. Even in a freezer at 0F, there is no separation, and in fact it was still flowable - barely.

Strider now has 28,000 miles on blend, currently on V90.
