Diesel tickover

[Guest]

From a boating point of view the greatest problem we have in canal
narrowboats is that the engine needed to propel the thing at 2.5 mph needs
to be about 7bhp. But to stop it we need a lot more flat out in reverse -
like 30bhp.
The result is that the engines don't really soot-up, but going along
forwards at tickover, be it a 'traditional slow revving type of engine or a
marinised Peugeot or Mitsi, the bores glaze thus using increasing amounts
of oil and the rings gum-up.
So you either run a basic HDD 30 type of oil or a multigrade specially made
for the particular boat engine. But generally multigrades are detrimental
as the additives are the cause of the glazing.
I think you will find that oil sold for taxi engines is more of a
traditional type than a modern multigrade - told to me by an oil industry
friend a while back I admit.
Well anyway, its got me thinking of my boat which I can at last see at Easter.

Hi Jon
If I was in the money I would not be driving an 80, more like the new vx for
110.000 euro with every thing I ever wanted in it and live in a place I
could use it like Aus or America, but tis but a dream. I will have to stick
with the cruiser that some one else dident want.So would I be right in
saying that you can let your cruiser idle for a while once you give it a run
at some stage, cause its the run that gets rid of the soot that builds up.

Years ago detergent oils were used in diesel engines, why has the
industry gone away from this? They certainly prevented gumming.
