Dear ALL
 
Just wanted to express my sincere thanks to all of you who responded to my emails for advice. The wealth of knowledge and exprience on this site about diesel engines speaks for itself. You have all given me a lot to think about and questions I can put to the team representing this inventor.
 
I am going to be meeting with them on Tuesday 14th next week to receive a presentation and ask as many questions as I like. You can bet that I will be putting many of the points you identified to them.
 
Just to answer one of the questions raised by John500 regarding the lease strategy versus purchase. Apparently the list price for one these items is approx $20,000 . This was percieved as being prohibitive for truck owners to find, therefore
the inventor has a deal with a lease company (financial house) who purchases the unit up front but leases the unit to the truck owners over a 3 year term. At the end of the lease the truck owners pay a greatly reduced peppercorn rent but never own the device. The peppercorn rent entitles the truck owners free software upgrades as required.
 
Apparently the inventor also has an insurance policy which indeminfies the truck owner against any damages or loss for the first year should the product malfunction in any way. I believe there is also reduced cover for years 2 and 3 but I'm not sure what the terms are.
 
I know this may all be pie in the sky and I wish I had some decent knowledge about diesel / LPG engines, however at least I've been fortunate to find this site and ask the wealth of experience on it, THANK YOU ALL once again
 
If nobody has any objections, I would like to keep you all posted as to the outcome of the meeting, who knows, if it turns out to be genuine, the world is a big place and you may want to exploit the opportunity for yourselves
 
Thanks and regards

You said "I wish I had some decent knowledge about diesel / LPG engines"
 
Why, why, why, why would you take an interest in an investment area where you admit you have no 'decent knowledge'????????
 
Run away, run away, run away!!!!!!!

I used a K&N on my ford diesel and all was fine. If you go to the jeep lib. diesel forum, they reduce mileage by 10% as they seem to mess up their system as they are not set up for dif. filters. BR

acetone in fuel by sailormon

I just happened on this site and so am throwing this out. As soon as it is posted I plan to duck out of the way of incomming jibes. Go to pureEnergySystems.com and check out artical on acetone in fuel. I did a short term in the last week or so trial with no real difinitive results, but will throw them out there anyhow. My little car which always gets 26 mixed driving did get 30 mpg for the first time. I will run long term to check this out further. My diesel ford 250 seemed to run nice and I was at 450 miles on a tank before I put fuel in it, only a half a tank as it is being sold in the morning. The only significant thing here is, I need to fill up when traveling before 400 miles on the highway and this tank was stop and go and mixed. Interesting enough to follow a little further with this from my view. Br

You know though, an article written by a chemist telling you that acetone dissolves the compounds of which fuel injection seals and O-rings are made isn't a "jibe" exactly-- it's a fact that one should give serious consideration.
 
PureEnergySystems also says this, by the way:
 
"CAUTION: Acetone degrades cheaper plastics. While we would expect that all components used in all automobiles would be of a more durable nature, this may not necessarily be the case."
 
One screw up in your fuel injection system and all the gas "savings" are out the window, BIG TIME.

That thought came to me also considering some of the shody shorcuts that seem so prevalent in manufacturing today. However I did read that some of the additves that are commonly used in fact contain acetone. I am not advocating their use either, just searching for a way around big industry price gouging on fuel, but that is an issue for another forum. Perhaps we should go to mopeds and park our suvs. BR

You know, if acetone were some sort of trouble-free miracle, it'd be in all the pumps in all the gas stations in all the world, but it isn't, because it isn't. People will tout "conspiracy theories" time and time again, but in fact it is totally impossible to suppress any product that is so readily available to everyone as acetone is.
 
If it were all true, a gas station could easily add it to their underground tanks and totally annihilate every other gas station within a five mile radius.
 
Why don't they? Obviously, fear of product liability.

OBD-II Interface and SW to improve Engine Fuel Economy by user777
Sep 26, 2005 (9:02 am)

A general question,
Does anyone know of a company that designs software for an OBD-II interface that apply's a little expert knowlege and suggests to the user what could be the cause of poor / off-design fuel economy? Is it even practical?
 
It seems many posters in the past few months are complaining of poor fuel economy (no surprise with the cost of fuel right)?
 
While the OBD-II interface can be used to read and reset codes and look at real-time parameters for different devices that are monitored, it would seem there would be a market to design software that would help localize the root cause of poor engine fuel economy / performance. I realize they can help locate causes of poor emissions, but what about the fuel economy portion of the equation?

This doesn't sound like the right approach to me....ultimately, ANY computer read out is only as good as the person reading it, and I don't think you can actually nail down anything certain using software like that....I would think it would be better to do a real world dyno pull or two and read out the tailpipe. Then you have some "real" numbers.
