2 Stroke oil in diesel

http://www.freel2.com/forum/topic878.html

Not sure about all this??

I read that it needs to be watwer cooled engine 2 stroke oil so that it is in engines of the same temp range. Air cooled 2 strokes run hotter I think.

hi
while at supercheap yesterday
i read the container advice on 3 brands of 2stroke oils and found that penrite/ ampol and castrol all have multi purpose use of there 2 st oils /can be used in both air and water cooled engines and the oil ratings were the same for each above brands - except - i bought the ampol racing grade as they claim it is for higher horepowered engines so for what it's worth
cheers

hi
sorry folks
a correction to above
it was valvoline racing oil
not
--ampol--
i addition despite valvoline claims that there oil is for higher hp engines they still charged the same as the other 2 brands $9.90 ltr and same specs jasco fc, api tc, iso gd.
but theres is especially recommended for higher hp engines under stressed conditions
so is it just word power play in advertising ????? how many times have we all been duped by this
cheers

Hi mazcan,
That Valvoline oil is the one I use.

I've found it at KMart for $7.50 a litre, big saving over what Super notso Cheap are charging!

Geoff

Roachie, would like to give this 2 stroke oil a go, what brand of oil are you and others using in your diesel, and does the ratio of 1:200 equate to approx 300ml of 2 stroke oil to a tank of diesel (70 ltrs) ?

Cheers,
John

John, at the moment I'm just using some Mobil stuff I got from a local motor cycle place. Not sure of the exact name of it.

I will be trying to buy a 20 litre drum of the stuff when this current 4 litre drum is finished. This is the 2nd (of 2) of these 4 litre drums I bought. Before that I used Castrol 2T stuff.

I really don't think it makes a lot of difference what brand you use....any of them will have the same effect in my opinion.

Be aware that a lot of people report that they don't initially notice ANY difference, but after a couple of tanks full, you will see the difference.

Cheers

Roachie

Sorry, forgot to answer your question about the ratio......

If you had a 200 litre tank capacity (I actually have 256 litre capacity in my 2 tanks), then you would use 1 litre of 2 stroke.

So, for 70 litres you should use about 350ml of 2 stroke.

Basically, if you take the amount of diesel you've just added to your tank and divide it by 2 and divide by 100. So, 70 litres divided by 2 = 35 litres....then divide this by 100 (simply move the decimal point across 2 spaces), means you need to add 0.35 litres (or 350ml).

Roachie

Roachie and others,
try this price for 2 stroke oil.

Thanks Rockape,
That's a very good price for 2-Stoke oil, I'll give them a ring and see what they can do freight wise!

Geoff

Roachie - were you recently at Braidwood NSW? with a bushranger caravan on back ?

seen one there a few weeks ago fitting the same description as your Patrol

No mate, although I did go through Braidwood the wednesday before Xmas and the wednesday after Xmas.....down and back on both occasions. But I was travelling bob-tail; camper was parked up and I was just taking SWMBO to Ulladulla and then went and picked her up again a week later.

The dye is good for, 'did I, or didn't I add oil?'

Most of the stuff I saw was on euro common rail cars (focus, golfs etc etc). I'm putting it in a CR motor - mind you I'm just a guinea pig with next to no mechanical expertise, but judging by the sheer weight of numbers of users through europe, I decided I should give it a go. So far so good.

May I inquire if the vehicle you drive is a 2wd or a 4wd? If so is it exactly as the dealer sold it to you?

4wd yes

Fair enough, the reason I ask is that most, not all but most 4wd's I have seen and at my age and state of disillusionment that is quite a few have various accessories fitted even simple mods such as better tyres.
Any car maker has to manufacture a vehicle with one eye on performance and the other on price. This being the case I don't think it is a matter of knowing better than the maker but rather a case of finding a better way to solve any shortcomings dictated by the dreaded cost factor. Sure diesel fuel is full of various additives and fuel available for extreme climatic conditions of for instance extremes of cold have additions to combat "jellying" at this low ambient. Why not make all fuel the same? Simply because it is not needed everywhere and adds unnescessary cost. Fuel is after all just another product and has to compete with rivals.

Also, it's not so much a case of what modern diesel fuel does have in it. It is more a case of what it DOES NOT have in it.

The boffins decided several years ago that the percentage of sulphur content in diesel fuel needed to be reduced from (I think) 5000ppm to 50ppm. This was for pollution reduction purposes.

Okay, so new diesel engines have been built with this level of spec in mind.

However, older diesel engines (eg: my dinosaur 6.5 Chev V8) NEED the extra lubrication which the older-spec diesel fuel provided. Without it, they have a tendancy to wear-out rubber seals etc in the injector pump as well as the fact that the injectors and top end of the engine relied on the extra lubricity of the old fashioned diesel fuel.

Adding the 2 stroke oil to the diesel puts the fuel back to somewhere near being what it was before.

Roachie

Hey Roachie,
They test all fuel for lubricity, and even tho they have now reduced the amount of sulphur in the fuel, they still add whatever they add to bring its lubricity rating to what is was before.
Spoke at length to a BP chap a while back regarding this and a few other things.

I also use 2T 2 stroke at 200:1, and get better mileage, reduced noise, etc.
Word of warning, use the mineral 2 stroke, not the synthetic one.
The synthetic 2 stroke dosent stay mixed like the mineral oil.

hi folks
well i added the valvolene 2st racing oil $9.90ltr to my vw 1.9ltr diesel common rail injection engine
last sunday and have now done nearly 500km's
most of that towing a 6x4 trailer to perth and back

and while there shifted my daughters and son in laws furniture to another rental clocked up 150km doing that and pulled some heavy loads with ease
car loaded as well each trip did 16 loads had power to boot in the traffic

the vw is running much smoother and is now exceptionly quiet
particularly noticable on start-up it also has more power

as far as fuel consumption goes i'm reserving any comments about that until i do a couple of trips with/out a trailer in tow for a more accurate comparison

the most impressive thing i have noticed is >

that after idling at the traffic lights for long periods before adding the 2 stroke oil

it would puff out a cloud of grey ash/dust from the cat convertor as i accellerated away from the lights

this was a regular thing in city traffic or after stopping at the first set of lights after a long road drive and idling for a period then taking off

that grey ash /dust is totally absent now not a sign of it

i'm impressed enough to continue the use of the 2st oil additive in the diesel fuel tank and confident that it is going to be benificial to the engine ( having read all the forums and blogs on it) not only now but in the long term

as an ex -farmer i have tried just about every additive that has come on the market over the years in various engines types

i can honestly say i have never been this impressed after trying something out

in the longer term only time will tell but it's all positive for me and will be keeping a watch

i already have fuel figures for the entire use of the vehicle since new 2005 now done 75000+ km's so will soon know if there is any change in fuel consumption down the track one way or other the vw is out of warranty so i carry the- can-!

cant buy the 2 stroke in wa as cheap as you guys are getting it in the east even at k-mart

so be it
cheers

Hi SK,
Firstly, "2-stroke oil will be absorbed by the diesel by forming an emulsion, which will not seperate."

It's different process from mixing with petrol. The other thing that happens with petrol and oil is evaporation. The petrol is more volatile than diesel and most of what you saw is certainly 2 stroke oil but also a great deal of the heavier components of the petrol that haven't evaporated as fast as the more volatile components.

There is plenty of information on the web pertaining to the subject. One of the best resources I found is this thread on a UK Freelander forum: 2 Stroke in Diesel

It's good mainly because the relevant information is in one place.

Geoff

Thanks I appreciate the link :)

If you use mineral oil, it will not seperate.
There are known issues of oil seperation when using synthetic 2 stroke in diesel.

Google it.

That should read 90lt tank. (bloody keyboard has a mind of its own)

Hi Geoff

What motor is in your patrol?

I have 2004 3.0ltr with 140,000 km and no issues to date, what are your thoughts and others regarding using 2 stroke oil in my motor?

Cheers

Rob

hi Robb , i bought a 2001 gu patrol new in 2001. A mate had a 2000 model which turned out to be a lemon from day 1. All newer diesel engines are built for a lower top endlub system from the fuel they use. I would try using 2 stroke oil for .....say 2 refuels and just see if there is any change. The 3 lt motor is a noisey 4 cyl motor and it is prob due to the emission gear involved. The issue is not really with the motor , but with the fuel that is being sold these days

Give it a go as more oil in the fuel will not hurt it.
Cheers Geoff

Hi Geoff,

Thanks for the info, was just abit nervous about putting oil in the fuel tank as this motor to replace would be quite abit. When I had a L/cruiser 60 Series even using quality oil and 5000km intervals there was always sludge when I changed the motor oil so I put diesel in the oil filler and ran around town for 30mins then dropped the oil........omg that really got the sludge out so re-filled with new oil ran around for a week then dropped oil again and still more sludge came out. I purchased that non-turbo vehicle with 198,000 km and then fitted a turbo soon after, I owned until it was stolen with 380,000km and no problems with the motor.

Cheers Rob

Now you mention it, I have a dim distant memory of the subject!

I guess it is somewhat similar as ATF does have lubricating properties as well as hydraulic properties.

My thoughts are 2 Stroke oil is designed to be combusted where ATF is designed to have a certain resistance to high temperatures.

Geoff

I have a 1984 HJ60 with 375,000 kms. Third owner. All of us have been using an additive similar to Chemtech Diesel Power for the vehicle's life. Its in a yellow bottle. Doseage about 1 ml for a litre of fuel.
Not sure if this gives the same result as the 2 stroke or the ATF. The bottle says it will do wonderful things.
Anyone else been using this additive?
