MOA is basically transmission fluid with one or two seal conditioners added. The old wives tale about ATF being so good at cleaning is completely false.
Luckily there are ways to care for your transmission and avoid a costly repa.
Adding transmission fluid to diesel fuel. Ive got what might be a really dumb question. Ive been told by several diesel mechanics that I should add 1 qt. Of transmission fluid to my fuel tank periodically as this would QUOTE Ive heard and seen this done too.
It is supposed to help de-crabon the engine and lube parts and pieces. A known practice especially amongst truckers is the adding of Automatic Transmission Fluid ATF to diesel fuel. According to tests performed by the Society of Automotive Engineers SAE and the International Standards Organization ISO the lubrication benefit from ATF is very slight.
Sun Sep 13 2020 916 am Post subject. Adding trans fluid to diesel fuel. I have a friend who was an Allis Chalmers dealer for over 50 years.
He recommends a quart of ATF in a diesel fill up. It lubes the pump and it has an affinity for moisture so it removes water from the fuel. It also adds Kinetic energy to the fuel as it too burns.
The earlier diesels were designed before the US bureacrats mandated low sulpher diesel fuel. Adding just a LITTLE oil to the tank would bring the lubricity up to the level necessary to prevent injection pump damage. The later models however have hardened barrels in the pump and require no additional lubricity in the fuel.
So today I was surprised to find a couple of drivers who put a quart of transmission fluid in each fuel tank whenever they fuel. They explained that this keeps the injectors running clean and lubricated and is a good idea if you fuel up with bio-diesel. Another guy also suggested 2-cycle engine oil.
With the admin of ULSD 15ppm this old timer has a diesel tank he adds transmission fluid to it not saying its right or wrong just wondering if anyone else has dealt with the ULSD this way. The new fuel injection systems would like the added lube. The old timer runs about 15 tractors and few loaders doesnt have to many issues we hear of.
The main reason for using an ATF is for increasing the lubricity of diesel when used in CRDI engines. It will help the high pressure pump live longer. With good quality fuel there may not be any advantage but if you put by accident a few litres of petrol in the tank then adding Dexron III will increase the lubricity lost by the addition of petrol.
Been hearing from alot of people lately that its best to add a quart of transmission fluid to the fuel tank every 2-3 fill ups to clean the engine good. In a diesel engine its fine. In fact you can burn straight ATF but it isnt good for it at all.
There was an article in Diesel Power magazine recently about a guy who burns about 70-80 ATF in his powerstroke. In a gas engine it does nothing more than adding engine oil. The old wives tale about ATF being so good at cleaning is completely false.
It does the same thing as running 2-stroke engine oil. Adds some lubricity back to the ultra low sulfur diesel. Running 2-stroke oil is a lot cheaper plus and this is going way out on a limb here if you had enough ATF in the fuel and got dipped it could look somewhat like red fuel and that is a whole bag of troubles there.
The use of automatic transmission fluid in diesel was started back in the days of the first low sulfur diesel and was added as an injection pump lubricant and cetane booster. It is still used when taking a mechanically injected rig into Mexico and using their PEMEX diesel. In addition BG products makers of BG44K have a product called MOA.
This product is designed to be added into the crankcase when changing the oil. Many people use it at every oil change and swear by it. It comes in a beer can size so I would assume it contains 16 oz.
MOA is basically transmission fluid with one or two seal conditioners added. Adding ATF or engine oil to the fuel of diesel powered trucks went out with mechanical injectors and mechanical fuel pumps. It was used many years ago to improve the lubricity of the diesel fuel which hopefully would increase the life of the injectors and pumps.
Old outmoded remedies take a long time to subside it seems. With the onset of ULSD I atarted adding Power Service and since my LP died last week I am adding 10 oz of TC-W3 2 stroke oil per fillup as well. ATF is a no no as is anything synthetic.
Folks say 2 stroke will clog injectors but the Power Service keeps em clean. No more smoke than usual and engine is quieter. I dont think transmission fluid is very good for my fuel system but iam going to run a couple tanks through with straight diesel then add 2stroke oil and see if i get the same outcome.
I also did this on my dads 05 rollback towtruck with 580k 15k on new injectors and got the same results. Have any of you guys had the same exspereince. Answer 1 of 16.
I realize this is an old post I am not a Professional Mechanic and I dont care to be to be honest with you but I did sell Speed Parts to hundreds of Professional Mechanics in the Bay Area Sacramento and Stockton in the 1980s when I worked at. I have heard many pros and cons to adding two-stroke oil to diesel. I would especially be interested in hearing from a tribologist attention Lubemaster77.
The recommended ratio seems to be at a ratio of one ounce of oil to one gallon of fuel. Additionally others are touting the benefits of adding Automatic Transmission Fluid ATF to ones fuel but. The transmission fluid burns at a considerably different temperature and rate than diesel fuel.
I know of several people that swear it works but I also know of a guy that found out he had 4500 of repairs on a Cummins N-14 after using transmission fluid. After hearing this I decide to try this out on a mofied OBS Powerstroke of my dads It gets 16 MPG and is really doggy getting up to speed. I pumped 4 gallons of NEW Trans Fluid into my front17gal tank and then topped off with Diesel.
Drove 10 miles on the interstate and after getting off i noticed a bigg difference in acceleration. It was actually easier to get up to speed. A transmission can be one of the most expensive components in a car to replace.
Luckily there are ways to care for your transmission and avoid a costly repa. Accually the use of tranny fluid in the fuel was to help clean and lube the injectors. Transmission fluid had a detergant in it to help clean and adds the lube that the ULSD fuel dont have.
If you have an engine that does not have a dpf system it will help with cleaning the injectors. I was told something like 1 pint tranny and 1 pint 2 stroke oil per 100 gallons of fuel. Instead use a diesel fuel additive designed to keep the combustion chamber clean and lubricate the fuel system like AMSOIL Diesel All-In-One or AMSOIL Diesel Injector Clean.
They work better and are far easier to use compared to metering out a few tablespoons of 2-stroke oil and finagling it into the fuel tank without making a mess. Back in the day when I was an over the road driver we would add a can of automatic transmission fluid to a tank of fuel to lube the injectors. Im not sure if this worked or was just an old truckers tale but we did it.
Of course that was when diesel was 35 cents a gallon and a can of transmission fluid cost about 75 cents. Your mileage may.
