I know some one that is running 100% ATF as fuel is this not recomended for a 2005 4X4?

 

Tell him do not run ATF in diesel fuel. ATF has friction modifiers that will damage the injection pump and injectors and plus other additives that is not meant to be burned.

thanks alot

 

ATF does not hurt a transmission pump so why would it hurt an injection pump. I am no expert on CP3's but I would have to have proof that it would hurt it or the injectors. I have wondered why no-one has tried used motor oil. I know of a generator that has ran 20% used motor oil with no problems. He runs his machine shop off the genererater. The man claims if he had enough used oil he would run a larger percentage but 20% is just what he can come up with.

 

With the tighter tolerances of the CP3 and injectors, the friction modifiers in the ATF will cause abnormally high wear that you won't like.

I've read about several people that do run some % motor oil in the fuel. But there are no friction modifiers in the motor oil. I think if it is filtered well, it shouldn't be a problem.

dont take offense but that is terrible advice for anyone with a 3rd gen HPCR.

the tolerances in these motors is very different from the old 12v's of yester year. there are numerous diesel additives on the market specifically for diesels and there is no reason to run ATF. waste oil will do nothing more than clog up the filter and dirty the fuel system.

i know #2 is expensive but suck it up or else the repairs will be very very costly IMO

I was just looking for an cheaper fuel resource. Is there anyone in the austin area making bio-fuel and if so are they selling any?

 

dodge recommeds a maximum of B5 IIRC...i thought they were talking about making it a higher percentage but im not sure.

do you work your truck or is it a DD

brett

 

Im no idiot and have worked on cars all my life but have not had to do anything yet . I just get my services done at the dealer.

 

what are you talking about? im asking do you drag trailers around or have a heavy load in the bed...working the truck, or is it a Daily Driver (DD)

brett

 

Sorry first time user on a forum. I drag trailers when I haul my rock crawler , sometimes 2 rock crawlers.

 

alright, well ill try to do some research on the acceptable limit of bio. im off to the gym for a few hrs so ill check back on this thread later and see if anyone else has any ideas. just dont use ATF...if anything its more expensive than diesel...even at 1.50 a quart, that 6 dollars a gallon. biggest thing you can do it run stock tires and keep it near 60

I have messed around with using 2 stroke as an additive (mixing at 200:1 or so), I have seen a slight increase in fuel economy and did notice the truck seems to run a bit quieter and smoother.

 

a tranny pump makes less than 300psi.
cp3 upwards of 26000 psi. tighter tolerances, requires much greater lubrication. you run atf, you will wipe the oil wedge off the barrels and be buying a new cp3, cause the dealer will see the red in the fuel, and off goes your warranty.

 

Welcome Aboard firecrazy; being rather new around here you may not realize that there is a fuels/biodiesel forum located in the General Forum here on DTR:
https://www.dieseltruckresource.com/...play.php?f=110

Lots of good info on fuel/additives/bio/jet fuel/gelling/etc. can be found there.

I'll second the motion on not running ATF as fuel.
