I haven't worried about the low sulfur fuel that came out 4 or 5 years ago, but now I think maybe I should have. I did a search and there seems to be a real problem with some of our older diesels (pre 1995 or so) without some type of hardened components in the injection pumps.

It's hard to tell what the truth is. A while back, someone here called several refiners, and seemed to get the answer that their fuel isn't a problem, but I'm not sure they were talking about the older diesels. One of the additive makers, stanadyne, indicates that 70% of the fuel they tested fails lub tests, but who knows what tests those are.

It seems that lots of truckers and farmers are using additives.

Is it just as simple as adding 4 or 5 ounces of new motor oil at every fill up, or is that too simple.

Have you been using an additive, and what type. Has anyone had an injection pump failure, possibly caused by the new fuel??

Thanks
Joe

Joe, Try REDLINE (co.) diesel additive.
Either one of the 2 products as they are
likely the same.
The 1 oz. oil is safe also.

If your worry is premature wear of the original injection pump barrels in your 123 pump, your worry is warranted.

You don't, however, need to use an expensive additive. Simply buy some cheap 30W, or whatever, oil. I got some private brand 30W that was as golden as honey. Pour in just an ounce or two per tankful. That's all it takes.

When the sulpher content was lowered in the early nineties, I was warned about the sudden high failure rate of injection pumps so I began adding a splash of oil every fill up. The car went several hundred thousand miles after that with NO injection related problems.

Your other alternative is to rebuild the pump with the hardened barrels now available from Bosch or MB. They are about $100 each plus labor in the clean room, plus labor to R&R the pump.

Good luck,

Where can I get some more info on using (FFF) french fry fuel. Sounds like a fun and useful project.

Will the fast food places give you the grease...I've heard that they have contracts and aren't likely to give it away.

Thanks for any info.

Joe

Hey donkey! Don't get mad, use the technology that the treehuggers are pushing! I did and I'm glad I did. It saves me about $50 per week making my own biodiesel and the 300TD just loves the stuff. It smoothed out the idle and the performance hasn't changed a lick :~) Tom

240Joe...There was a post a while back...subject was "what does yours smell like" I don't remember right now, maybe it was even on a different board. ( I bounce around a lot :~) There are a lot of places online to get biodiesel info. You can start at http://www.veggievan.org , or http://www.dancingrabbit.org/biodiesel/flrecipe.html and then there is http://biodiesel.infopop.net/2/0/opentopic I think one of the ones posted here was http://journeytoforever.org/biodiesel, and there is a pretty good write-up at http://home.swbell.net/scrof/Biod_proc.html, that should keep 'ya busy for a minute or two :) As for getting gease, I really haven't had too much trouble. I started out with just my cousins restaurant. Now I have several of them paying me to pick theirs up. I'm patient, I will wait until a contract expires and then I will pick up that restaurant for a cheaper price. ( why should I have to charge what the waste haulers do? I'm getting paid to pick up tomarrows fuel) Also, this is a very busy time of year because of all the fairs and carnivals etc. These folks don't have a good way to dispose of their oil. They will just about kiss your feet for taking it off their hands. I picked up 75 gallons last Sat. at a county fair not a half hour from my house. This Sunday I have to pick up an estimated 115-125 gallons from a county fair that is 20 minutes from my home. The following Sun. I will travel about 45 minutes one way to pick up about 140 gallons from another county fair. Then we get into the BIG Free Fair and another very Large midway event about an hour away. It's not hard to find when you start to inquire here and there! They (the state) only has one toxic waste dump and it is the ONLY place you are allowed to dump used food grade oil. (It's near Detroit, a few hours away) Michigan has also (this spring) recently put a "road tax" on Methanol (a key catalyst ingrediant)so my price per gallon of "the juice" has now skyrocketed to about .46 per gallon. That is why I'm working on a methanol recovery system at the present time. If I can get that to work I will get the price back down to around .28 per gallon. You can always email me if you need help or have questions. ( make sure you put biodiesel in the subject , as I do delete a lot of spam without opening it esp. if I don't recognize the name! ) Tom

Hello fryerpower. I just figured out that you are the person that delivers my paper. I was following your car the other day down M37 and I could smell the fryer grease.

Please send email. I would like to stop by sometime and see how you make the stuff.
