How Does WVO Affect My 616 Engine?
 

I wanna hear from every chipper charlie to every debbie downer about the ups and downs of WVO in the 240D engine (which includes things like IP) on a two-tank conversion. I have not tested my oil for anything and gravity filter down to 5 microns.

Think this thread could be considered trolling?;)

Debbie Downer :D - I ruined a set of injectors by running on 100% WVO in 90F heat and then the fuel congealed in the IP causing me to strand the car at Santa Monica Beach Pier overnight. I got the car running the next day but man it nailed like crazy after that. :(

All depends on the way you Dry your oil, and prepare it for use as a motor-fuel...

All WVO contains Moisture, FFA and other nasties. Most nasties can be Filtered out by filtering to 1 micron...

However, FFA and Moisture Cannot.....

FFA = Free-Fatty-Acid. This is an acidic type of oil.....

FFA will turn Moisture Acidic.....

This will over time destroy the high-pressure pumping elements in the fuel pump...(Expensive to replace)

FFA Without Moisture is fairly innocuous...(Banning Moisture completely is nerly impossible due to tank condensation issues etc. Veggy-oil is mildly hygroscopic, meaning it likes to absorb a certain amount of water from the air......)

This is why its VERY important to Properly DRY the oil before it get anywhere near any car fuel-tank...

Providing the oil is prepared for motor use PROPERLY then there are no real issues. --Not even a twin-tank needed, providing winter-temps dont drop too much below 0 deg C-- IF the Engine and Injection-System is prepared properly, Unfortunately this Seldom done--

(A 'Twin-Tank' is good for 'feel-good' factor but if the oil is crap, then so is the life-expectancy of the fuel-system...)

Well, I won't be altering my injection system and it does drop rather far below 0 degrees centigrade here in Massachusetts some nights, so I think I will keep my twin-tanker. As for water, though, what is the best way to remove it?

Your going to kill your motor. Just run it on diesel, thats what it was designed for. I have seen to many old MB diesels ruined by people using WVO. In fact last month my buddy and I were trying to get a 1980 300TD with 200K running, the PO had run it on WVO and had ruined the motor. The compression was about 150-200PSI in all 5 cylinders, motor was toast..

How can you be sure that that WVO caused that low compression? How would it? And, although these engines were designed to run on mineral diesel, I'm sure you've heard, the original diesel engine designed by Rudolph Diesel ran on peanut oil. I'm just trying to get all the facts here.

The car was run on WVO for 1 year and then it started running really bad and then one day it wouldn't start. To be honest I have no proof that it was the WVO but why else would a perfectly good car loose all its compression in 1 year. The car only had 200K on it.

I assume it ruined the valve seals causing the low compression.

What about all those people with 30,000-50,000 miles logged on WVO? Maybe the previous owner didn't take the necessary actions to properly run the engine on WVO?

In general, with properly de-watered and de-contaminated WVO when used with a proper two-tank system, WVO will PROLONG the life of your engine. Cut corners on either and you will cut life from the engine. This is from over 30 years of WVO experience.

Could you post a link to thread(s) that describes the proper de-watering and de-contaminating process? Or bump them to the top?
I envisioned running WVO when I got my 300SD, but just don't want to destroy such a fine vehicle. The parts car I have access to, became a parts car because of poorly treated WVO. (low compression and N/G IP)

So you think that a diesel engine designed by MB 50+ years later is exactly like the low output plant oil engine that Rudolf Diesel built? It was engineered to be run on diesel fuel! WVO was never intended to be run through these engines, they are very precise, and junky nasty fuel will only cause wear and damage. Why even bother with diesel so cheap now? Run it on what its meant to run on!

Its your $$ when you wreck your motor.

Alright, negative nancy, so is properly refined WVO still "junky nasty" fuel? And seeing as I don't have a secure income, mineral diesel is still expensive now and it's gonna shoot right back up to 5 bucks a gallon this summer. I also don't fancy to see what little money I have going into the pockets of those damn oil sheiks.

I burn it,no problems two years.Compression all in 400s with 305,000 miles.
However 2 tank,heaters,and 70% with diesel added.

I've run three summers primarily 100% filtered to 1 micron WVO. No problems.
