2 stroke oil (2SO) as an additive to diesel fuel

[Ryeman]

What's your take Transporter or was your past post on the subject definitive?

I thought this was a good informative post from what appears to be an ideal source.

Lower EGT post.
I'll make this the last one to qualify previous posts and note it's less 2SO than the usual 1:200 but a marked decrease in the EGT.

"However a side effect for me is my EGT's are warmer by 50-60C when I forget or run out of 2ST for a fill.
So effectively I have 50-60C cooler EGT's with 2ST @ 300-400:1 mix."

On the flip side, there's also one person I noticed that was complaining about overheating (post 574)

Stopped using castrol 2t all together. Kept having overheating issues, only really when going over 100kmph. Stopped using it and no more overheating.
Didn't really notice any other difference, not going back to using two stroke oil.

I found a few that claimed it caused problems but proved to be other causes in the end. That one makes no sense but hopefully they will post if it proves to be something else and a coincidence at the time. It's a one off and if it's caused by 2SO it's strange that the thousands of people using it haven't had the same problem occurring?

But sometimes that is what happens. You can't discount a negative report just because others haven't had the same issue. Statistically, the guy is in the minority but his "score" still counts.

Thousands?
Are you sure about that?
And I wonder how many were/are DPF equipped.

If you have a cruise around the interwebs you'll find "thousands" is probably quite a conservative estimate. We aren't just talking the AU market, which is relatively small. Look at the Euro / UK diesel car fleet and you become aware of how many use the stuff.

Look at a few US forums & it's surprising how many are using it in their petrol vehicles at 500:1 or in the numerous F250 diesels, Dodge Rams etc. I wouldn't have believed it either but they're out there.

Have you ever actually modded a vehicle or ran/maintained it outside what most would consider "the normal boundaries"?

I agree, thousands is a stretch, but mostly because you really can't tell from the evidence available how widespread the usage is. It'sa all guesswork.
If you read thorough most of these threads with an objective mind, it really looks like each forum has one or two people who absolutly rave about using it, a couple that say its a bad idea for whatever reason, a lot who post only once or twice to report very short term findings and the rest who look at the the apparent benefits and make a decision about whether they can even be bothered to do it.
I like to think I'm a fairly objective thinker. I'm not ready to call this one as good or bad, and no amount of argument short of a scientific paper with clear test results is going to convince mW either way, until I've had the time to prove the benefit or lack thereof for myself.
For instance, as Australians, we should all drink more water and eat less meat, but mostly we can't be bothered, even when there's plenty of evidence to support it. I can't see that many of us are going to be convinced by a whole lot of second and third hand circumstantial evidence that we should add 2so oil to our fuel for an unproven benefit.

It's not like tossing dice type statistics. If it actually caused a problem then I want to know how 2SO caused overheating for obvious reasons. That's why it makes little sense as a one off.
