hello
Do you add 2 stroke to your diesel?
I have got a recommendation from my mechanic to use 1 liter of 2 stroke oil when filling a full tank with diesel.
I own a 220 cdi e class 2005
any opinion or suggestion will be highly appreciated.
thanks

06 E320 here and curious as well. I have heard similar for trucks and reports of running more 'quietly' but didnt see anything about this in the MB literature. But that doesnt mean it wouldnt hurt to give it a try... Following this post to see any reports of others running this in our cars

No, never. Even for my 2-cycle Detroit diesel.
The issue of injection pumps lubrication was hot when USA switched to low-sulfur diesel, but life proved all the worry premature.
Now all US diesel fuel has % of bio, what is good lubricant.
Might be different in Albania, so check what local owners say.

Why not use a product that's actually designed for diesel fuel?
FPPF total power. 1 ounce per 8 gallons finds its way into every tank of fuel in my car for the added lubricity.

ULSD isn't very slippery, and I don't believe kajtek1 is right about bio being in all US diesel. One can get 10% and 20% and sometimes 100% biodiesel around here, but I'll not be using it in either my truck or my car. Too viscous and I don't see that being OK for the crazy high pressures common rail diesels run at. It also has issues with clouding at not-so-low temperatures.

Liquified Dinosaurs. It's what's for dinner.

I use opti-lube XPD for 4 years now in my 06 E-320 CDI

I think it is the law that each gas station has to disclosure the pricing (like 40% of fuel price in CA is tax) and formulation.
Obviously they don't want to make those things too visible, but in CA I see warning on diesel pumps that the fuel might contain bio.

In my opinion it's a good practice to add small amount 2 stroke oil in an older Diesel with mechanical injection pump and no catalytic converters or particulate filters of any type.

My 1984 F250 with 6.9 L Diesel is a good example:
When the rotary injection pump governor started sticking up and engine was stalling it was fixed instantly by adding 2 stroke oil!

Now 12 years later it's still running like the day when it was new!




I use Opti-Lube Summer Blend in newer Diesels with recent US emission controls.

I have tried this 2 stroke oil with 3 full tanks one after the other.
I put 0,7 l oil and directly fill it fully with diesel, in order that the filling process will mix good the oil and diesel
after that I have tried to use only diesel and tried 2-3 full tanks
I dont feel any change in pedal sensitivity, speed , noise or vibration
maybe it is something theoretical that it isnt visible in practice ?!?!?

It will reduce wear in parts that get their lubrication from the fuel.

In the previous post I was referring to this type of injection pump:

the only questionmark that I have is for the injectors
I am not sure if the oil can make good or bad impact on the injectors, but I was referred to add it form my mechanic, maybe he is wrong ?!?!

All I can say is I use it in old off-road equipment like 1960 bulldozer with 2-stroke Detroit Diesel engine, mid 80's Diesel powered farm tractor, as well as the old Ford F-250 Diesel pickup.


OptiLube Summer Blend etc. would be better (and legal) choice for for a modern passenger car!

Good luck

what about abro ds 900

any feedback?

I have never had a need to use this or any other type of liquid Diesel cleaner.

I don't think it is a lubricant?

albania

no its not a lubricant, but a cleaner, hopefully it will clean the injectors and the common rail parts
I was told that 2 stroke oil cleans the injectors and help them work better, because diesel in my country is ruining all the cars
I have a Vw golf 2013 with 2 damaged injectors at 25.000 km already
