I wouldn't mind knowing which brands either, I have done a bit of reading on a few different websites and it seems to be the go to add oil.

Oscar and Greg,
I have used various brands but at the moment I am using Gulf Western Outboard Motor Oil TCW-3. I believe you can use Aircooled two stroke oil as well, but I got this from Supercheap at a good price.

Greg and Oscar,
You gave me pause to check that this oil was organic as I understand that you should use organic or semi organic for this purpose. Checked on the internet.....Bugger me it is synthetic! Not to be used. You have no idea the time I have taken to find the right oil for good price. Ah well, after a tank of straight diesel, I will use another brand. Makes the car quiet though!!

Re: 2 Stroke oil as an additive to Diesel fuel

I use any brand of "AIR COOLED" 2 stroke oil, NOT SYNTHETIC oil.
Have read a lot on the subject on world wide sites, i.e. BMW etc, and all say not to use the water cooled 2 stroke or synthetic oils.Think most watter cooled oils are synthetic. Mainly use Gulf Western or Penrite, depends which is the cheapest at the time.
Don't think it makes much difference which brand as the mix is very diluted.
Works well in my Prado and definarely no smoke and exhaust sediment doesn't look any different. Nearly 150,000k's and going great.

Re: 2 Stroke oil as an additive to Diesel fuel

Perhaps someone with a D4D motor that is experiencing the cold start rattle, and who is out of warranty may be interested in being a "test case" to see if adding two stroke to their diesel fuel tank would reduce the rattles in the morning.

At a 200:1 ratio, this would mean a dose of 900 ml of two stroke into the 180 litre fuel tank for a fill up. Might as well as throw in the whole 1 litre.

The brand of two stroke to use is the Castrol Activ 2T, which can be purchased from Supacheap, Bursons or Repco. It's around $11 for a 1 litre bottle of Castrol Activ 2T.

Would be interested in finding out if this additive reduces the cold start rattles.

The reason why I ask for someone who is experiencing the problem and out of warranty is because a vehicle that is under warranty will probably need Toyota's full attention at resolving the rattles issue, but someone out of warranty has nothing to lose (except for the rattles!) :mrgreen:

Nothing to lose? Unless it grenades the motor :roll:

Re: 2 Stroke oil as an additive to Diesel fuel

There's no evidence that adding two stroke to diesel fuel will "grenade" a motor in a ratio of 200:1 and heaps of people have positive personal testimonies about noticeable reduction in the diesel rattle. Some even claim fuel economy benefits. Certainly there is documented evidence that two stroke oil has benefits and so this is a call to any willing participants who are interested in the experiment.

Toyota support a maximum of 5% bio diesel, so it's easy to see that adding 900ml of two stroke mix into a 180 litre tank equates to less than... well you can work it out for yourself.

Re: 2 Stroke oil as an additive to Diesel fuel

I have a bog stock 120 TD and have run the test in another thread where I am monitoring different fuel brands and tracking the difference in fuel economy as the mods go on.

See here for the full thread;

http://myswag.org/forum/index.php?topic=7881.15

and here is the two stroke test;

TANK NUMBER FOUR - 11.76LPHK

TYPE OF TRAVEL
Around town with 400k on tassie backroads

KILOMETRES TRAVELLED
1421 km

FUEL USED
165 litres

BRAND
Caltex Vortex

COST
$212

KILOMETRES PER LITRE
8.5kml

LITRES PER 100K'S
11.7 LPH.

Filled up with Woolworths diesel.

Interesting that I got EXACTLY the same economy as before.

This was the tank that I put the litre of two stroke oil in the tank at the suggested rate.

It did nothing to the fuel economy, nothing to the power (well of course it cant because the only possible outcome is for it to lower the flash point as its a heavier oil than the diesel.

Was it quieter. Maybe. I think it sounded a little quieter but had no means of measuring it.

There is a definite increase in fumes from the exhaust when idling.

Plus you need to factor in another $12ish for the oil which would buy another 9l of diesel which effectively changes the fuel economy from 11.7 to 12.3 lphk.
So IMO its a crock.

The ONLY benefit is that it might make it a little quieter. But the only thing that it can possibly make quieter is the fuel pump. And they are built to tolerance. So pumping through sticky oil is going to do MORE damage by gunking it up than to leave it out.

So its official.......more internet garbage.

Have booked in for some new tyres. Slightly larger 70series instead of 65. Will be interesting to see how it changes.

cheers

Re: 2 Stroke oil as an additive to Diesel fuel

This would be a good starting point for those of you who have not read up on the subject.

The D4D motor is no different to any other diesel motor and if the ultra low sulphur diesel these days are not blended correctly by the fuel vendors, it will result in insufficient lubricity for the injectors and fuel pump. Judging by the issues experienced by so many owners with injector problems, I'd say that the D4D motor could use all the help that it can get.

I can appreciate that there may be folks on an open forum who will not openly say that they are willing or are already using two stroke in their fuel due to warranty concerns. Completely understand and good for you!

This post isn't meant to force anyone to do anything to their vehicle that they don't want to - it's just sharing some credible scientific analysis from knowledgable people. Consider it like a point of reference, and make of it what you will. I won't lose sleep just because I shared information which could improve the longevity of your engine and you chose not to consider it. It's your engine after all! :roll:

Two stroke oil is hardly what I would consider to be a "sticky" oil. The only possibility is that you're using the wrong type of two stroke oil. From what has been tested by many folks out there, avoid marine two stroke, as it is formulated differently for it's specific use. Use mineral based, low ash JASO-FC spec two stroke oil. The one that fits the bill best which is available in Australia is the Castrol Activ 2T.

Yes, I do agree that it adds to the cost of a tankful but unlike the Hiclone, this isn't a story designed to put money into someone's pockets and fool the gullible. That's because no one company or person gains by suggesting that increasing the lubricity of the fuel will potentially increase the longevity of your pump and injectors.

Just think about what it means if the engine is running with less rattly noise. The $12 isn't there for noise reduction, it's there to potentially reduce wear and tear on your injectors and pump. Sounds like a pretty cheap additive to me, if that's what it will do.

At least you've tested it first hand, and drawn your own conclusions. For you, your criteria is fuel consumption and fuel costs. For someone else this may not be their concern but rather for the longevity of their pride and joy for many years after their warranty has expired.

To each their own.

Wrong again :roll:

I have a letter from Toyota Australia stating that they support 5% biodiesel in their diesel engines. I will consider Toyota Australia to be authoritative on that point.

Re: 2 Stroke oil as an additive to Diesel fuel

Sounds like the jury is still out on what is right or wrong, good or bad for a diesel engine or specifically the D4D...
