Hi all,

Just wondering if anyone on here is running 2 stroke oil as premix in the diesel, I have used it a few times on other diesel cars and it has resulted in smoother engine running and reduced the 'diesel' noise a fair bit.

I am thinking of running it in my E300TD after giving everything a good service and probably some diesel purge though the system, as 2 stroke oil is meant to be burnt it might also give some cleaning properties as well. One of the reasons I ran it in other cars is due to the low sulphur diesel in the UK sometimes not giving the best lubrication to the fuel pump, adding some 2 stroke gives me the extra pump insurance!

Just wondering if anyone has used it on here at all?

Interesting.

I never have even thought of doing that but sounds doable, try it out but how do you know if it is working or not and how much do you use?

I do know that some of the unburned oil may get stuck in rings.

Like anything else always draw backs.

Won't it smell?

The fellow who I got my care from use to put a can of new trannie oil in fuel once in a blue moon. I never have.

will have the same effect. I mix 4 oz with every other fuel fill (averages out to about 4oz/10 gallons. I don't think the ratio is critical.

Two-stroke oil is sort of expensive. Any cheap lube will do. I use 30 wt engine oil.

I've been running 1% 2 stroke oil in mine since I got it (75k miles ago). I do it as a way of restoring the lubricity that was lost when refining out the sulfur in the fuel. Injector pumps were designed when diesel "was still diesel" so expect a certain level of lubricity.

Biodiesel is also a good lubricant and since many stations now pump 5-20% bio/dino diesel, that works too.

In the research I've done, most oils are high ash so aren't good for the engine. 2 stroke oil is low ash, designed to be burned along with the fuel so it isn't a problem. People obviously burn all manner of stuff in their engines from used motor oil, hydraulic oil, vegetable oil, transmission fluid, grease and so on, so arguably "it does work"...to each his own.

You can also buy lubricity enhancers, but many don't work as well as good old 2 stroke oil.

Oh, and it doesn't smell. (I use the WalMart house brand)

Here's the test data I used to make my decision on a lubricity enhancer -http://www.thetruckersreport.com/truckingindustryforum/attachments/trucks-eighteen-wheelers-/8175d1287154398-lubricity-additive-study-copy-diesel-fuel-additive-version-3-a.att

I have been doing that since they took the grease factor out of diesel about 4 years ago. I buy in in the gallon container, just dump a shot in before fueling, and the 617 engine does run well with the addition. I probably put in half a cup per tank full.

1983 Mercedes W123 240D 4 Speed 285,000 on the road with a 617 turbo, beautiful butter yellow, license plate # 83 240D INDIANA

2003 Jaguar Type X, AWD. beautiful, good mileage,
Mom's car, but I won't let her drive it!

I use it, I throw in about 1oz per gallon before filling up. The idea is to give the fuel some lubrisity to it. (is that a word?).
When they took out the Sulpher and the Aromatic Hydro Carbons, there went the Lubricity.

The idea is to give the IP, Injectors and Lift Pump some lube.

Adding oil to the tank every other fill up will give you a good concentration on one thank, and a
weaker concentration on the next one.

Years ago probably the end of the 60`s or early 70`s, I knew and old trucker that said he
threw in a qt of ATF to each tank on every fill up. said it kept the Injectors clean etc.... and that
was back before they screwed with the fuel.
ATF back then was more detergent than it is now from what I read.
Today the fuel looks like water compared to what it use to look like.

I first read about adding 2 stroke oil on a Dodge Cummins forum, think the guy name is MOPARMAN.
He said it increased his mileage and the engine ran better. He even had his Mileage before and after as I remember.
So after reading that, I have been adding it ever since.

Sure it adds to the cost to each tank, think a gallon at Wally World is like $13.
I keep one of their 16oz bottles in the trunk. It is graduated in oz`s, and say Iam at 1/2 tank, then 10 oz.
Also keep a qt bottle filled to add to it.

It is such a small amount, I don`t believe it will get stuck in the rings, burn pretty clean, no smell and don`t see any
difference in the exhaust, even at night in the head lights.

I run it when I don't have B20 in the tank (mostly when running HPR).

Seems to work well, and is about $0.50-1.00 per tank.

Lubricity is definitely a word. Appreciate you insights, I may have to try it in some of my cars to see how they do.

Good to see that some others are, I know its used lots on other car makes as basically insurance for the fuel pump, mainly for other higher pressure common rail pumps as those have a much higher pressure.

With regards to the type of oil, look to get 'low ash' 2 stroke oil, you can usually pick it up quite cheaply as its used in 2 stroke motorbikes. I haven't tried using any other oils with the fuel as of yet, will initially stick to 2 stroke again to see what the difference is.

The car I am pick up tomorrow is fairly high miles and I doubt it would have ever had any additives added so I will report back on how much differences it makes on larger higher mileage engines.

So, you're buying the NA, pre-turbo W210 E300?

I used to use a 40:1 premix size bottle in every full fill up tank. Then I realized that biodiesel is a very good "additive" to restore the lubricity of old Sulfur containing diesel. I fill up exclusively at Shell, and I'm content now with just running their 5-20% bio blend straight. In the winter, it DOES get cold enough here to require an antigel. I use PS Arctic Formula. That has what they call "Slick 50" in it. So I use that November, December, and January.

I would ONLY use 2 stroke oil for this purpose. Engine oil, ATF, etc. all will leave ash behind as they burn. Not to mention a bunch of ATFs these days are synthetic and made to strongly RESIST oxidation (or burning). IMO the injectors will stay clean if you use high quality diesel, and don't putt around town all the time. Occasional diesel purges help significantly.

Also worth noting is the fact that our injection pumps are lubricated primarily by engine oil. Yes, the elements do derive benefit from nice, slick diesel fuel. It's not nearly as important as on some trucks where the fuel TOTALLY lubes and cools the pump.

I run 1 oz/gallon of fuel because my other vehicle is a 24V Cummins with a VP. I add after filling up and let the returning fuel mix oil with fuel. I don't know that it is necessary on the older mechanical injection pump but it is cheap insurance. The cheapest plae to buy is WallyWorld gallons. I picked some orange 1 qt cans out of the trash at the parts store and split the gallon into quarts and store in the trunk.

So that 6.3L of used ATF I now have wont work for this purpose, possibly over 5 years old when it was fresh.

I use ATF to fill my Fuel Filters when changing them, and Iam sure a lot of others do it too. It may not be designed to burn as a fuel, but seems to when doing the change. I use it because I know it is coming out of a clean bottle, compared to using some fuel out of a fuel can. Diesel Purge will work also, don`t always have it on hand.

2 stroke oil is used in Chain saws, Weed Whackers and Blowers, think about it, only 2.6 oz in those over priced little bottles to a gallon of gas. And think about the speed those engines run on that thinly diluted oil in the gas to lube the crank, bearings etc,,,
Some incredible oil.

I still add 4oz to a gallon, probably from my old Homelite XL-12 and XL-101 days using about that amount back then. 2.6 oz makes me nervous.
At 4oz they smoke a bit more on start up, but haven`t given me any problems.

So 1oz in a gallon of Diesel sure won`t cause any additional smoke problems.

My 240D uses around a QT every 100 - 1200 miles. Wonder what kind of Ash Iam making out of her?

My opinion and reaction: God no!

I would never put used motor oil or used ATF in my fuel tank. Others here do, and that's their choice. It's their choice. The benefit is 0 and the risk to harm IP or injectors is substantial. Seems like a very clear equation to me.
