I was just thinking, at todays fuel prices, to go 1,000,000 miles.

It would cost $ 114,000

If your car got 25 miles per gallon

OUCH !!! that is a lot of green.

And you know fuel prices are just going to go up.

Hope this vegetable oil thing works out in the long run !!

Have Fun

Seems like that would kill the lubricating properties of diesel.

Bosch doesn't like it in is VP44 injector pump.
I think that is one of the rotary pumps isn't it ?

Rotary pumps do not seem to hold up as well as the in-line ones.
At least the ones I have messed with.

And I wonder what delaminated in the pump?
And exactly what they mean by delamination of the foil ?

Thanks for the post.
Have Fun Everyone

The VP44 doesn't like low fuel pressure. Dodge had to replace a lot of those. Apparently the lift pump caused some of the problems. If you want to know more about them, here is some good info. http://www.dodgeram.org/tech/dsl/ISB/Vp44.htm

My truck has the P7100 which is mechanically controlled.

They put the P7100 in the 1994 to 1998 cummins engines, correct ?

I am envious, that engine, pump combo seems to be bulletproof.

Wanna sell it ?

Thank You

That's correct. No I looked for it for a long time. They only made the Quad cab for a few months with the 12 valve engine. The 24 valve got the VP44. The PO bombed it and put a new transmission in it. I'm keeping it as long as I keep the 300 TD.

Five yrs ago I bought a 92 dodge 1 ton, cummins, showing 117K on an inop odometer. I paid $5K for this "farm truck" that I have used the last five yrs pulling 12K lbs (tractor, hay...) in addition to driving 30 miles to the ranch and 30 miles back home daily. I've taken many trips to Austin and around the hill coutry. I've no idea of the mileage, nor do I really need to know as it serves its purpose.
During that time I have run any where from 20% wvo in winter months to 100% wvo in the summer.

You do the math but, I suspect the fuel savings has paid for the truck and then some. So far so good...

I'll always use any alternative fuels I can get my hands on, in my beater 617...
In any of the cars I really care about I will never use anything other than Diesel (usually with 1 quart of 10w40 added per tank) or good b100 from the coop.

One day I tried some wvo in a 603. dilluted with 75% diesel on a warm day. It took a full on lubromoly- purge to get that engine to run right again.
I, like Forced, do not trust WVO in these engines. You may get away with it having a sophisticated 2tank system, but really, why??? what do you really save?? time?
some money? The Planet?

It is a beautiful idea, admitted.

Trust me I am no screaming environmentalist....

A 2 tank system does not need to be "sophisticated". You spend perhaps $300 plus some of your time to put it in. Heck I can recover that in about a month. After that it is all gravy. Plus I like the idea of not paying some Arab dude for oil.

So yes, I do save money. My ROI of this car is about SIX MONTHS. Plus I have met some great people and have fun tinkering with the car. Wife now calls me her gear head....

Oh perhaps in your 603, if a purge is what fixed it, perhaps the oil loosened up some stuff that got into your injectors. And that would have been a good thing.

I don't want to add fuel to the fire (or Diesel cycle) but just for reference I am posting what the EMA stated about non-processed oils (SVO and WVO)

You ARE risking severe damage due to viscosity issues.
They do not seem to have an issue with processed biodiesel.
Check out this month's STAR magazine for MB's take on this...

(Sorry for the pdf, the site would not take the jpg file as I already posted it in the thread "My Sister's 82 300D Won't start")

The same magazine that had an article saying ULSD is bad for the engines?

Yes. The article had great information about how the junk they are selling as ULSD does not meet the minimum lubrication requirements for even new engines much less our old ones. "Of 27 countries surveyed, only Canada, Switzerland, Poland and Taiwan have worse diesel fuel than the US.". I wish the article was available online so I could link to it, but STAR does not post articles.
According to the article MB likes Lucas fuel treatment and Octal OLI-9070 as lubricity enhancers. They also like B5 BioD but not a higher percentage.

here is another quote..." Diesel engines with injection pumps operating on used cooking oil or similar substances are at risk due to lack of consistency and testing to ASTM or API standards. There are simply no standards for these oils because of the variablility of the sources and owners treatment of these 'fuels' Some owners are simply filtering used cooking oil obtained at restaurants and using it to run their diesels. While this appears to be an alternate solution to the increasing cost of commercially refined diesel fuel, the lack of lubricity information makes such a practice risky considering the cost of an injection pump."

Well no offense directed at you, but it seem like MB is refusing to research or release info in regards to WVO, SVO or Biodiesel. But I understand in some aspect why they would be afraid to to say that using WVO or SVO or Bio would be OK as they stated there are no real standards set, and perhaps end up with a bunch of warrantee issues. Yet many of the "commericial" biodiesel producers are sticking to the Diesel standards.

Their main complaint with WVO/SVO seems to be with lubricity. Though more research needs to be done, sandpaper might have more lubricity than the ULSD that we have in the US. Most of the people that have used WVO claim that WVO/SVO has better lubricity. This research done by a professor at the University of Saskatchewan is most interesting: http://www.goodoilonline.com/page2.html I try to stay away from biodiesel or WVO sight for any research. But since this method of fueling a car is new, finding decent research is still tough. Though this from the University of Minnesota is quite interesting: www.emnrd.state.nm.us/ecmd/documents/FactSheetBiodieselSB48903-19-2007.doc

This from Cornell University: http://nyc.cce.cornell.edu/emerginginitiatives/Waste%20Oils%20&%20Fats%20Supply%20Final%20Report.pdf Talks about how ULSD has very little lubricity and how biodiesel is added to ULSD for ADDING lubricity.

i wanna see what mb board of directors' members also sit on the boards of petro companies...

just in case of a hidden conflict of interest...etc

I'm pretty sure WVO will never hurt a good high compression engine. That's just impossible.
It may very well hurt injectors and pump due to inconsistency or unwanted particles in the wvo that can't be filtered out. and thus the engine eventually because it could then starve a cylinder of fuel.
