Dear Is Mise,

Well mate, I will admit that is a new one on me. I will have to look into a bit more but it looks like you were right and that is at least part of the push to clean up our fuels. Just how much I have yet to determine.

Steele,

Thanks for that.

Anyone contemplating buying a diesel car/van/ute, new or second hand (particularly the latter) should think twice because the maintenance costs can become horrific.

There is also the new problem of sludge/carbon build up in the engines that requires expensive work to clean it out, a bit like the old days of petrol engines and regular decoking.

They'll have to come up with a new kind of Diesel for boats, because Petrol on boats is a no-no !

Only for fools individual.

I did 53,000 nautical miles cruising the Oz east coast & much of the Pacific islands in a yacht with petrol powered engine, Honda generator & outboard for the dingy. Petrol is fine if used intelligently.

Of course it is only suitable for boats, ships need something more economical.

Hasbeen,
And, Diesel even more so !

Diesel is fine on larger work boats individual. I ran a fleet of fast & slow tourist day trip, & overnight boats on the reef. Some of these could burn 500 gallons of diesel an hour at full speed.

The larger of these had the cabins, of 204 & 325 passenger capacity totally removed from the hulls on rubber mounts. These were fine, but normal boats always had some smell of diesel permeating the air to some extent.

I have been on many cruising yachts around the Pacific with that awful odor. Each time I started to think the much higher efficiency of a diesel, one of these would talk me out of it.

The fact that you still had to carry petrol for the dinghy outboard made changing from a petrol motor a bit pointless.
