These days car owners are trying to save money and look after the environment at the same time. As a part time grey nomad I thought I’d put pen to paper and let you know about a system I have been investigation.

• Diesel/LPG

Injecting LPG into a diesel engine has been around since Adam was a boy. The main problem was the delivery system was as old as Noah, but as history has shown us, technology has advanced.

There are at least two systems I know of that work great. The first one incorporates a venturi, which is plumbed into the air intake line just before the turbo. The LPG is feed via a gas converter through a computer controlled stepper motor.

The other system is a more up to date system that utilises sequential vapour injection again computer controlled. Both systems work on approx 1/3 LPG mixed with 2/3 diesel.

The advantage for the environment is that LPG injected into the diesel engine means that 95 to 98% diesel is burnt and converts to energy, compared to 70-80% on a standard diesel engine. This near total burn increases the power and improves the fuel consumption by at least a 1/3. It also keeps the oil cleaner and gives less soot over time which is great for the environment.

If you want more information, I found a website that explains this technology and gives details of examples. I went to and spoke to their rep here in Brisbane (Mr Spanner at Sumner Park) and was very impressed with their operations.

Definitely, worth the investigation, especially when you see the price of diesel these days in the country areas.

Happy Motoring
