Anyone else thinking about running 2 stroke oil in their diesel?

[GBC]

Only on my second tank so far so too early to get anything too definitive.

Using low ash mineral 2 stroke.

The MOST noticeable difference is that the injection rattle and the engine in general is much quieter so it must be lubricating something?

Power - nil change or minimal at best?
Eco - dunno - towing trailers and stuff changes my economy pretty wildly.

Seems a bit smoother - but then again it could be placebo.

Motor still goes

Testing continues........

Jimbamb, if I had a 3l nissan I'd be running the bastrd like the old B.P. zoom 25:1 mix

[spearking]

GBC I thing the ratio's guys are running is around 200:1 and that it is important to do a simple test and mix some of the oil your using with some diesel in a jar and make sure it does not separate to ensure the mix is not separating in the tank over time. Keep us posted on your project.... I don't think you will have any drama's ... i have read of guys doing it for over 5 years and swearing buy it.

[GBC]

Yeah, 200:1 for me, so far I've read that ANY cheaper mineral 2 stroke will stay in suspension...

Interesting observation...
When i use old fuel(OUTBOARD) in my 4 st HONDA lawnmower.everytime i start it after standing for a few weeks it puffs lots of blue smoke.Clears up fairly quickly..Is this because the oil has settled whlile standing..Does not do it on ord unleaded

I burn most of my old fuel in the corolla..It doesnt mind but i cant see if it smokes on starting and it is used regularly,,

Interesting! My 4 st Kubota mower which sees nothing but 50:1 does the same, it's long in the tooth now so I offhandedly put it down to valve seals, next startup I will stick my noggin in and have a good sniff.

cheers fnq

[oldboot]

its possible that the fuel component evaporates in the carby leaving the 2st oil behind.

My 4 stroke mower lives in y wood shed I if there is only a little fule left in the tank when I finish mowing...the tank is bone dry when I go to use it next time.

far as i know i would not dare to use anything than manufacture recommend not even to top up my engine with different oil or use any other diesel which thay are some on sale out there form some independent petrol stations

and i do not believe thay use in Europe any 2s oil in diesel in new cars as all this new staff coming from over there

something like sometimes called a DPF , is a device designed to remove diesel particulate matter from the exhaust gas of a diesel engine. Wall-flow diesel particulate filters usually remove 85% or more of the soot, and can at times (heavily loaded condition) attain soot removal efficiencies of close to 100%. A diesel-powered vehicle equipped with functioning filter will emit no visible smoke from its exhaust pipe.
In addition to collecting the particulate, a method must exist to clean the filter. Some filters are single-use (disposable), while others are designed to burn off the accumulated particulate, either through the use of a catalyst (passive), or through an active technology, such as a fuel burner which heats the filter to soot combustion temperatures, through engine modifications (the engine is set to run a certain specific way when the filter load reaches a pre-determined level, either to heat the exhaust gases, or to produce high amounts of No2, which will oxidize the particulates at relatively low temperatures), or through other methods. This is known as "filter regeneration".sulfur in the fuel interferes with many "regeneration" strategies, so almost all jurisdictions that are interested in the reduction of particulate emissions, are also passing regulations governing fuel sulfur levels

u can find this in so many new cars which got common rail engine

and thay not cheep at all if you clog one and it can not clean it self like for Hyundai thay are around $2500

and new high pressure pump thay dont like bio diesel at all thay crack open like rose

and i dont want to tell you what bio diesel dose to injectors and thay are $2000 each

it is nothing that bad at all thay give you big power and economy and green planet only what you have to do make sure where you buying diesel from and dont putt petrol in (and if you dont turn the key ) take car to dialer for service and you are safe

My way,

I've been trying to find out about the filter regeneration thing. I read in the OS forums that the euro cars have in the manual that they need to be run at highway speeds for 10 odd minutes once a month for the burnoff to occur successfully - or something like that. The holden I drive makes no mention of it (not that just because it isn't in the manual doesn't mean it shouldn't be done?)

I'm still doing it (about 8 odd tanks so far), with nil bad side effects. The 'test' cases I researched prior to beginning were euro common rail diesels (golfs etc)., with up to 5 years of trouble free motoring.

I don't take advice like yours lightly, that's for sure, and appreciate your input. I can not however, find a single failure of any diesel engine who has tried it. Mercedes mechs have admitted to running it their 24hr racing cars. On balance however, I'm not about to start shoving it down people's necks saying they should be doing it either.

I've heard you're a mechanic - I'd be happy for you to take a squiz at the internals of mine if you're interested.

Any d40 navara owners would worry about what you've written - they smoke like chimneys under a bit of load.

[ozassassin]

I have a Holden 3lit turbo diesel 4x4, it has on the clock 160,000 K's.
I will give it ago and see what happens my self, after reading all the other forums it sounds like it might have some merit.
Time will tell and if all else fails, damn i will have to get myself a new forbie.

If there were any clear benifits I reckon the oil companies would already be doing it. Remeber, any edge means more sales, and that is all they are interested in.

I'm sorry but that has been the a line trotted out for decades, as an argument against any form of fuel or oil additive.....sorry it holds no water at all.

Fuel companies must provide a universally compatable fuel..( suposedly)..as such they are very much disinclined to put any additives that may or may not cause damage to a single specific vehicle....they are not interested in testing an additive in all vehicles available...so they simply don't because it is easier...and thay have to deal with the parts warranty chain (mentioned later).......

There is always someone who will argue that any given additive will cause dammage regardless of its proven performance......remember it is one thing to prove the effectiveness of a process.......it is an entirly different thing to argue that in court......even if you win its expensive.

If you have a good read of the euro freelander site.....there is a bloke there who makes a very good case why it is very unlikly that any manufacturer will ever publicly endorse any fuel or oil additive.

and it is involved with the very complex chain of warranty and liability....almost no manufacturer makes all its own parts.......so anything other than the use of standard oils and fuels would have to be negociated with a endless chain of suppliers and subsuppliers of parts.

Remember in the corporate world.....the best option is to do nothing...unless you are forced to.

On the subject of biodiesel.....there are also plenty that are prepared to bag it and point the finger at it with the slightest provocation.

One of the problems with biodiesel is consistency.........particularly if it is home made......If the person producing the biodiesel is not skilled and has not got their process sorted there are a variety of reasons why it can cause all sorts of problems........just like contaminated or dodgy pump diesel can.

My brotherinalws first batch of BIO, cost him a few hundred dollars in filters, a long wait beside the road and a few days cleaning his tanks...since then he hasn't had a problem.....he has learned.

I have read several threads on this matter in their entirity........it is pretty easy to explain how 2 stroke works in the positive view and some prople have gone to a lot of trouble to test this.
There is plenty of detail to be had.

There have been several people who have come out against the idea......I have not seen any of them even attempt to explain a mechanism where by damage can be done.... and none have provided any proof or even attempted any testing.

As far as dammage to common rail diesels...( and yes this is a cheap shot)...they seem to be quite capable of damaging themselves when operated as instructed on normal fuels and oils.

on the matter of the diesel particulate filter.....if the motor is running cleaner and emmitting less soot (a claim of the 2 stroke thing)....how is that going to dammage the particulate filter?

As for both the particulate filter and the cat converter.....if the motor is running better and the injectors are opening and closing more accurately as designed....and therfore less unburnt fuel is passing..how can this be a bad thing for either.


Let face it pump diesel is a low order fuel that is problay less consistent and less engineered and specified than the 2 stroke that is being put in it.

Like others here I consider my self "A man of science"..I would be very interested to hear and well considered argument either way.

We all get stuck into the government when the legeslate to lock us out of green zones without any proof or science.

I am happy to hear your argument..as long as you can give me some proof or at leats a reasonable explanation of the mechanism.

To this point I have not read about a failure.

on many of passenger car here in Australia regeneration is done at service with scan tool
light truck got thay done it self whale you driving and it takes around 20 min. lots problem we see people turning engine off in middle of regeneration process (which you should not do )
and e.c.u. will try do one again and agin to till it had enuff and putts engine in limp mode but many people dont know what is that light on dash so 1st think day do thay stop engine .

city cancel drives live this as thay have to seat on side of road to till process is done.

Mercedes and Audy and many of BMW have system call add blue which thay can refile everywhere in Europe on all petrol station here only available from dialer but tank of 12l will do something like 10000 klm

on this system thay dont have particulars filter it is this blue staff injected in excuse to burn exes of rubbish on this engines you can not see any smoke coming out

if the car dont have DPF or add blue system thay very fine cat. converter.

. which can be very easy clog if dont use low ash oil etc

[oldboot]

lets talk reality here... most of us that would be thinking of this would have dirty old commercial mechanicaly injected diesels that do not have common rail injection, and definitely dont have DPF and very unlilky to have a ACT converter.

If I had a common rail diesel, I would not be putting 2 stroke in it.... mostly because I wouldn't have a common rail diesel.

That said...there are plenty of people running either 2 stroke or BIO diesel in their common rail cars in europe........just have a look in the bio diesel forums.

i was camped on frazer isl in 1983 i was driving a 1983 landcruiser we went to the main land 1 day a week into two week stay i pulled in to a service station got out and a fella said yes mate i said fill her up i opened the fuel flap diesel in red rite there i went in to get some gear i paid the bill and left we had 30 mins to get the ferry back off we go 8ks down the road i felt a little miss and messed me pants. i turnedoff the moter instantly into neutral pulled over nowing wat that rotton insane minute little worm had done to my new cruiser i drained it after getting towedback on the ferry then over the island syd was happy he got 90 litres of petrol and i had to pay island price for my diesel i was told to use some 2 stroke in by a diesel tech i rang and i did 1.2 mill klm in that baby the cruiser i have now is a 188 hj60 321ooo just run in i wold not swap for a new one have funn all hilly

Some interesting test results for anyone who's doing it.
The Colorado is still going strong and quiet.
