Hey, Im not 100% on this one. I have some specs but I will have to dig deep into my notes to find more. I'm also not sure what the specs are on our pickups. These specs also vary on engine model and of course yr!!

HEUI oil pressures fall into range values 485-4000psi
NOP with HEUI is 5000psi
HEUI transfer pump 30-65psi
Caterpillar EUI 5000psi
NOP on most Cat EUI 5,500psi
HPI-TP gear pumps are constant 250psi
Cummins using HPI-TP has 4 ECM actuators ISX cylinders heads also have 2 common rail passages that do Timing, metering, and fuel drain. Cummins Celect Plus ECM's have fuel pressure at 1200RPM minimum of 120psi
Cummins Celect Plus NOP is 5,000 to 25,000psi and 150psi to charge injectors.

Most of the specs are very similar and remember WHATEVER we have in our cars, pickups, ect.. ALL of it was in tractor trailers first. Example.. HUD and Heated seats all our luxury options were introduced in the truck world first!!! Same as EUI and HEUI and all other injection systems. High fuel psi and systems were in the big rigs first!! It's crazy and can get in deep, but Im no expert just learning!!

I found this on this website. This is specs for our trucks posted by an admin!!

what about useing the 2 stroke in a lmm dura? anyone got any exp. with that one

 

Personally, I wouldn't run any types of oil or trans (ATF) in any of my fuel besides my weed wacker !! Like I said before its all personal pref, but according to the books, any kind of oil contaminates diesel fuel causing blue smoke..Soo if you think it's cleaning out your injectors and or manifold, your actually burning oil.

Hey fellas,
Try quick experiment, take a clear glass, fill it with diesel and add your 2-stroke and mix it up!! Leave it sit for a day or two, if you take notice the oil will or should separate from the fuel. Oil is thicker and will not, does not add lubrication to your fuel. It sits at the top of fuel tank and when it burns just causes blue smoke, actually contaminating the fuel. Sorry guys dont want to hurt any feelings but you are just wasting money. If you are really concerned buy a product meant for diesel fuel.

 

before you make a comment you should look at information provided by studies done on additives. HFRR we all know how easy the vp can die. The ulsd fuel is hard on these things. I run the amsoil diesel concentrate in my fuel all the time. I don't trust fuel companies to put the correct amount of things to help with cold weather etc. They are there to make a profit, not keep trucks going. They just want you to buy fuel.

 

I hear ya but you should used diesel fuel additives not 2-stroke oil !! And the fuel companies aren't going to sell shity fuel if the want customers to come back. Like I said 3 times personal preff. Buy fuel from name brand companies not like GAS LAND or EAGLE!! There is plenty of test that been proven thats most additives are b.s. To each is own!!

 

You should try that experiment for yourself sometime and get back to us. Can't wait to hear the results.
So, just exactly what do you think diesel fuel is then anyway?
Don't know how your fuel system works, but the fuel in my trucks is constantly being circulated back and forth between the engine while it's running. I been burning used motor oil mixed with 2-stroke in both my trucks for years. They don't smoke unless I want them to, via my right foot.
I'd estimate my saving related to the fuel adds I used over the past three years amounting to at least $1k by now considering the fuel volume itself (extra half gallon/tank), increased MPG and repair costs never incurred due to maintaining my pumps and injectors in top running condition.

Sorry dude, but you're just plain wrong.

Cite?

 

I do agree that with the new fuel, we do need something as a fuel additive to make up for lost ctane and lubrucity. But i do agree however with the fact that using 2 stroke oil is just a waste of money. I will email my rep from power service tomorrow and ask if they have tried/heard such a thing... But hey what ever blows yer hair back....

 

Why not run 2 stroke oil it is something that is designed to burn? We are taught a lot of BS in school. I know a few people that been through the diesel tech programs and would not let them touch my truck. A lot of times the schools are paid big bucks my certain companies to push their products and ideas. I do by diesel from the big names, but doesn't mean they do anything for the fact that we now have to run ulsd. You say additives are bs, but how do you support this knowing that independent test prove they actually help. I am not doing it for added mpg gain, but to keep my vp alive. I have almost 200k on the original one. Had the pump tapped since 120k but have had a steady diet of amsoil diesel concentrate. The ones I know that don't add anything have gone through 2 pumps. Had to pull the tank due to the fuel sender not working and my tank was nice and clean inside too.

 

Easy buddy I dont care what u guys want to put in your fuel. I understand diesel is type of oil or same type of principles but nowhere near motor oil. Yes, buy additives meant for diesel fuel. but sorry dude..2-stroke and oil, ATF, w.e is WRONG!!! I have books from school stating it contaminates fuel. Just sharing what I was taught in DIESEL school, not contradicting anyone, do as you please!! Thats like if you have oil heat which is type of diesel , and add 2-Stroke or motor oil to it....it's going to eventually ruin your furnace. They have special furnaces that burn used oils!! Can't imagine what it does to the flashpoint!! Try mixing diesel in your motor oil!! ANYWAY I'M DONE!!!! KEEP ON TRUCKING!!!! By the way we are here to help each other not argue!! PEACE!!!

 

DonnyK, all you have brought to the table here is what you say. Like I asked before, cite the books and studies you claim unless you expect us to just take your word for it.

Sorry, but I don't know you from Jack, and from the sound of your postings I'm becoming less and less inclined to believe anything you post. I don't play the he-said, she-said game or refer to any phanton test studies, just my own personal experience. Take it with however many grains of salt you choose.

If Tinman was smart he wouldn't put much stock in what some salesman trying to sell him product says either.

Can't wait to hear about that.
