Hi Guys.

A couple of weeks back there was a discussion which touched on trucks
putting some unleaded petrol in their diesel tank to increase horse power
for mountain ranges etc.

I tow quite a large boat and, while my MQ Turbo Diesel does not have too
much trouble pulling it, I was wondering if a little bit of unleaded may
help it along a bit better or should I not even think about trying it?

What would the mix ratio be if I did?

What are the pro's and cons of doing such a thing?

Best regards

Who knows?

The best way to find out is to procure a spare engine in good condition
than experiment with ever increasing amounts of Petrol on your current
engine.

When it goes bang, use the mix ratio that preceded the detonation.

You will maybe save someone else a lot of work, and keep a poor vehicle
wrecker in beer for another week.

The bottom line is that it is not a good idea....

If you need a more powerful vehicle, buy it. If adding ULP to diesel helped, don't you think the fuel companies would be blending
already?

I say, fit a HIclone and a Prozone Fuelsaver. :)

Actually, I was going to ask about the Prozone. A workmate has just bought a new diesel Courier ute, and has fitted one. Repco is
selling them. I await his results after a few weeks of driving :)

A slow google led me to the answers I wanted

Did you know that gullible is not in the dictionary?

Well one con would be that it will burn out your injectors and probably cost
you around $1 500 to replace. Depending on the amount of the mix, it may
well fork your engine completely. The time to burn out the engine will be
dependent on the mix ratio, the higher the ULP to quicker the burn.

One pro would be that for a couple of days, or maybe a week or longer for
small amounts, you would notice a considerable increase in power and
acceleration.

Personally, I wouldn't be touching it, unless you have a really old engine
that is on its last legs anyway and you are basically wanting to experiment.
Even then I wouldn't travel to far from home - no further than your willing
to walk or catch other transport as when it goes there will not be any
roadside repair happening.

Cheers,
W.
