93 Chevy 2500 6.5 liter turbo diesel

Carey Russ · #1 10/02/05, 04:25 PM

Thats my truck and I want to start running it on bio diesel either b20 or some slightly higher combination as I have found that I can buy 55 gallon drums of B100. The research I've done says basically that I have one the worst trucks to do this with and that they just converted the gas engine blocks into diesels-- My truck runs great I think- it has 240,000 miles one it I have had engine work done on it. I wish I coudl afford to buy a newer Dodge or something but I can't --anyone have experience with these trucks -or tried running them on biodiesel. Thanks

.....Better to just keep on running regular diesel than try to experiment and scewup something like the injector pump , etc. and then you've got to spend big bucks to just back to where you started . This biodiesel trend is replete with stories of people thinking they can just fillup with Mazzola and take a trip . If these stories are somewhat true why aren't the vege oil companies marketing their product and it's capability to make fries at McD's and also power the diesel in their delivery truck(s) ??? There is alot I don't know about this subject but I ---- sure ain't going to put old cooking oil in my ford diesel . fordy...

Biodiesel and SVO (straight vegtable oil) are different things. Biodiesel starts as vegtable oil and is then treated to make it into biodiesel, which has very similar properties to perto diesel. It's my understanding that the risk of running properly made biodiesel is pretty low. There are people also running their diesels on SVO, which requires a dual-fuel system and starting/stopping the engine on normal diesel and then switching to SVO during the trip. This is where the older, simple diesels tend to work better than the new direct injection computer controlled ones.

How much can you buy a 55 gallon drum of biodiesel for?

Its about 160 dollars for 55 gallons of b100 here in montana, made here too.

We have a 95 chevy 6.5 diesel that we run on veg oil/diesel mix. We filter the oil with a pump first and then from the filtered oil make our mix. The only way you can screw up your pumps is by putting straight unfiltered veg oil into your tank, which will cause your pumps to clogg with all the waste in the oil. Right now our cost is down to almost nothing to run our truck. Email us with your question my boyfriend has been looking into doing this for a long time and he can explain to you into more detail all the technical stuff.

The diesel engine was first made to run on straight peanut oil, but the petrol compagnies had to get their hands on it. Right now if you start looking you will find that actually getting used veg oil is pretty hard. I agree that you have to go through a few steps to use the oil but way worth the fuel economy. In Europe right now VW actually makes a diesel engine which you can buy with the conversion already made so that you can run on straight veg oil...

Biodiesel is a superior fuel when compared to petroleum diesel. It has a higher cetane value, better lubricity factor, burns cleaner, and its higher solvency factor actual removes deposits left by petrol.
I have been using B100 in my 92 Ford diesel for about 20,000 miles with no problems.
A few drawbacks to biodiesel include its higher gel point than petrol, (easily solved by blending BD and petrol in temperatures under 30F, and/or installing an inline heater to your fuel system. My Ford has a fuel filter heater, not sure if the Chevy's do). Also, since BD is such a better solvent, some older rubber fuel lines are eventually degraded by the stuff. Most 'newer' diesels (anything past about 91 or so) use synthetic fuel lines and so are not affected.
And yes, I have actually poured a few gallons of filtered vegetable oil straight into my fuel tank, blending it with biodiesel. It works. There are long term consequences of such a practice, though, the injector nozzles eventually get a deposit around them, that will adversely affect thier spray pattern. This is prevented in dual-fuel vehicals by purging the veg. oil from the fuel system with BD or petrol prior to shutting down the engine.
But as far as BD and injection pumps go, the BD wins hands down over petrol. Low-sulfur diesel fuel puts more wear on the injection pump, due to its lower lubricating properties.

Fordy, it's a little different than old cooking oil.

Minnesota started requiring 2% biodiesel in all diesel fuel just last month. Up to 25%, it is a good thing & helps lubricate the engine.

You might be thinking of the straight veggie oil stuff some folks are doing, which is totally different? That recycles old cooking oil.

Biodiesel is newly refined oil from soybeans, canola, or the like & processed into a real fuel first & formost.

What do you use to filter the WVO?
I have now collected about 50 gallons of WVO and want to run a blend of WVO and diesel in my Dodge CTD.

I can get only about 5 gallons a week from my work(we don't fry a lot...) but know a few other restaurant owners in the area.

IF I could filter the WVO then I would start using it.

By the way,I get the WVO 'straight from the fryer' so little worries about water....

Thanks.

Oz, you can get sock filters from McMaster Carr pretty cheap. They have a few different mesh sizes, a ten-micron mesh would be equivalent to an auto fuel filter. (someone correct me if thats wrong,it may be 5 micron...sorry)
Cold filtering will catch more junk, it will also take exponentially longer.
Honestly I dont have much experience with filtering waste oil. When making biodiesel, I rely on the chemical reaction and seperation to do the bulk of the filtering for me, that is, most of the junk goes to the bottom of the reaction vessel. I then siphon (actually hand crank pump) the good stuff off the top, getting 95% of the product into my holding tank (55 gallon drum mounted on a 4-wheel cart). When it's time to fill up my truck, the biodiesel is then hand-cranked up with a second pump, and is pushed through a stainless steel 100-micron filter, connected to a diesel fuel filter, then into the truck.
Its all pretty simple once you get set-up, its good to have an outdoor area where you wont be worried about making a little mess from time to time, because dealing with cooking oil tends to be messy.

Oh, and some of the water present in waste oil comes from the food that is fried in it. It settles out readily, especially at higher temperatures.

Carey Russ, I think it's somewhat common for diesels to be just modified gas engines. I know in volkswagen's 1.6L diesel (common to the 80's rabbit, the jetta, the quantum, the caddy, the vanagon) the BLOCK is identical for the gas or the diesel models, it's the HEAD that is different.

Carey Russ · #12 10/07/05, 08:44 PM

Thanks for all the input-- I've been planning to mix the B100 I can get here in Mt with regular diesel to run my truck -- it is cold here already-- But I here soon we will be able to get winterized BD. I'm excited about running on BD or SVO! I just don't want to mess up my truck which I need out where I live.

Few option to filter your wvo,
You have to filter your oil down to 5 micron , wicht is the stander micron recoiment filter in any diesel engine. you can use the bag tecnic, (at a cost of about 10 to 30$can each) you simply filter oil true those bag (they look like milk filter) by gravity , some hippy even use jean's, wich filter to about 15 micron... but i think the best way is to built a filter sation... go to your local part shop and ask about what kind of oil filter they carry ... find the oil filter mount for them ,join two together, use 25 micron and a 10micron water remouval filter cateridge (the water is from what your cooking , not only with bad storarage) if you patient you can probably go to a junk yard and get the full systeme togheter for real cheap(exept new filter)... i built mine for about 125$ can all with new stuff. (but can built one for about 25$)next get yourself couple of old 45 gallon barrel (for free if possible) , you will also need a wire mesh filter (70 micron) use in hydrolic tank for filtering.. cost about 20$can its look like a mesh tube.... so with 3/4 gas hose, conect the wire mesh (will be use to pump from your restaurant jug.... to a high viscosity pump... connect to the filter station . the other end of it just run a hose to a clean ans dry 45 gallon barrel. sound complicated but real easy i can send you picture if you whant? but remenber this will only give you clean wvo you will have to mix it will regular diesel to run it in your truck. exept if you live in a real warm country!!!! in theoty wvo have to be filter , heat up to 180c(the same temperature as your coolant)before you introdure in to your engine , and that only because oil as a higth viscosity!!! so if you lucky like my and live in a moderate climat you will be ok with mixing 50/50 , every time you do a mix keep a sample in class jar outside and have a look at it every couple day, you will notice if you mix is getting thicker, so next mix just add more diesel.
lot of benifit to run on oil , better for polution (no acid rain), better for you engine (and you will notice rigth away!) better for your wallet.

To andswer some of you who wonder why vegetable oil compagnie dont advetise that !, the reason is sample ,the vegetable oil cost about 1.09$ liter and diesel just ( at some place)whent over that price (in america anyway). but if you look in europe you will find some compagniy who advetize the benefit of vegetable oil for your car!!! And d ont forget that it not every one who have acces to wvo... its one good thing about being a Chef!!

happy driving
Jess

Hi ,
i have a 95 3500 chev turbo diesel dually wich i paid use 22 000$can and run it on strait wvo (Waste vegetable oil) bio diesel is a diferrent thing and garranty to be harmless to your truck , but not nesesary cheaper... the big trucking compagny use that b20 because the tax break, but it run about same price or more of regular diesel...

by the way oil is way better for your engine !!!! you only have to find a way to reduce the viscosity of oil, before it get to your injector. you can buy a good kit for 750$ us or if you like me, built it yourself for cheaper( and have a good excuse to spent time in the shop!!!!!!!)
well i say :go for biodiesel no probleme (even better for old engine)but if you whant some real economy go wvo....
and yes you do not have the best engine but it work as good with oil that diesel... make sure to remove the pmd (to hot by the pump)and fix it on the far panel... should be done anyway. Do not go newer than 95 in american truck ... they change the injection system ...
happy driving

To set the record straight on "converted diesels"...
It's been an old "wives tale" for years that Chevy diesels are converted gas engines but that was never the truth. The 350 (or 5.7) diesels from the '70's did share some external parts like exhaust manifolds but the internals were all purpose built diesel items. The biggest reasons that they had problems with those was... not using strong enough main and head bolts AND putting diesel engines in the hands of people that were used to driving high rpm gas engines.
As far as the 6.2 and 6.5 diesels... good engines just not the most powerful. Didn't he say his truck has 240,000 miles on it?

Ok, now i'll climb down off my soap box. LoL

We just got the injector pump change, and it's like driving a new truck!!!!

It's all about maintenance!!
