Let me introduce my self, my name is Arthur.
I was searching for information on internet a while ago regarding the 2 stroke oil added to diesel fuel.
The reason i did it was quite simple. I own tractors, and maintain forests. My hired "tech" employee suggested adding the 2 stroke oil.
I em a skeptic person, but keeping in mind that my tractors do very hard work day after day i was thinking it may help them bear the stress better. My tractors are underrated in horsepower for the job, but size of the tractor i can use is verry limited so i have to abuse small tractors.
So, anyways the advised oil was the oil i use as the addictive for the chainsaws. Husqvarna XP 2T oil.
I registered here to share what i found out about this.
First of all, the tractor i work with (and love all of it to the last bit) is a russian make. So not realy a sensitive one.
3 cylinder air cooled, 3 liter 4 stroke diesel engine.
Rated for 45 ish horses, maximum rpm is 2000.
Adding the oil actualy did not improve fuel consumption at all.
It had zero effect, it did not get any worse, nor any better.
Since this is an air cooled engine i do keep my eye on the temp gauge. I did notice that it did not deveop as mutch heat. I runs a bit colder (around 5C what i can absolute confirm for continous full load -was actualy fixing the road by towng a large block of cement-)
What else i noticed was absolute visibly less smoke at full load.
Other than that i did not notice anything special, using it with 2 stroke oil for over 3 months now. Since it is a very absued tractor (mostly i pull loads that make her do a wheele when starting) every bit it has does get a regular check. It means an oil change every week, just to give an example.
During the checks i did verify that there is a noticial reduce in carbon deposit in the exhaust system. I em writing here now becouse the cylinder head has been removed to check the pistons and cylinders. This is done every month. Deposit of fuel leftovers did reduce by a large amount.
Actualy i did try this 2 stroke oil on a nother tractor with the same kind of engine, but that has only 2 cylinders and does light work. It just powers a circular shaw. The effects on that tractor where close to nothing at all. Including the temperature.
I try to be enviroment friendly, so the oil was used with the fuel of the cars we own. (see if i can reduce the smoke) That includes a turbo charged car. I did not notice anything with that, not even the reduced smoke no mather how hard i was driving it.
I allso have an older version of that car with a non-turbo charged engine. The effects where noticibly reduced smoke when accelerating, other than that i did not notice anything.
I have a 4 stroke petrol engine powered people carryer car, to name it it is an UAZ. It is used to transport employees to absurd places. I have absolute good results with thatone. At idle rpm that car is rocking hard, the engine is verry harsh. After adding the 2 stroke oil it did became more behaved. Fuel consumption did not change at all, but the does benefit from using the 2 stroke oil. It is mostly used on rough terrain (i keep that old junk as i just can not find any alternative to it)
the performance did change, mid rpm tourqe did increase. It can be clearly felt, onroad and offroad too.
the last subject of test was a lada niva, petrol 4 stroke engine.
The increased mid tourqe was not observed, nor other effects regarding the engine. Niva with the injected engine is notoriously eating fuel pumps. Dirt cheap, thank god. Around 2 months was the life cycle, but since i use 2 stroke oil added to the fuel i had no problems with the fuel pump.
To sum up what i found out:
-> natural aspirated 4 stroke diesels under constant high load produce less smoke, and do not produce as mutch heat
-> natural aspirated 4 stroke diesels with up to medium load did not gain anything i can confirm
-> turbo charged 4 stroke diesel did not gain any benefit (intresting)
-> natural aspirated 4 stroke petrol engines may (depending on engine i guess) get improved tourqe at mid rpm, and smoother idle.
-> it seems that fuel pump with injected engines do gain longer life. but suposedly proper modern fuel pumps outlast engines, so its not a real benefit.
A nother person in this industry uses a forwarder that has a 2 stroke diesel engine, and allso adds the same kind of 2 stroke oil to the fuel. Has observed the same as i did with highly loaded engine. To name it, less heat, less smoke. Carbon build up was not verifyed, that engine did not get disassembled for checkups since the 2 stroke oil is in use.
I can only confirm less carbon buildup for my 2 tractors, even the lightly loaded tractor did have less of it since 2 stroke oil is used. I em sorthof betting here, but since i seen no drawback of using it only occasional benefits i do use it with every equipment i have regardless.
I was told by other mechanics that manufacturers do not approve 2 stroke oil in 4 stroke engines to produce emission figures acceptible. Adding the oil would produce some of the figures to be worse than without. Intresting, as i observed less smoke, and less carbon buildup at the tractors. I em not that educated in this stuff. Something about the ratio of CO and CO2 emission the "tech guys" where refering to, actualy i did not understand it so i might recall it wrong.
Anyways, the ratio suggested to use was 1 liters of 2 stroke oil to 100 liter of fuel.
I would be excited to know the reason behind the LESS smoke effect realy. I em sure that the oil i use is a reduced smoke oil, nothing special about it. I do not purchase other kind of 2 stroke oil, nor i did experiment with any. Other oils make chainsaws do a lot of smoke and smell realy bad. I purchase this oil in large quantity so i had no reason to try other brands/types.
