Does LPG wear out an engine more than using petrol? Should I expect a
shorter life from a car that has been run on LPG or at least more
repairs needed?

Is it more risky buying a 2nd hand car with over 100k on clock that
has been converted to run on LPG than a standard petrol one?Could be
why the original owner got shot of it?

LPG burns much cleaner than petrol and the oil is therefore much cleaner
for far longer. This reduction in suspended particles in the oil can
only be good in the long term for an engine.

Of course, just because it's an LPG car doesn't rule out bad treatment
of the engine by the driver.

I thought I read somewhere that some engines (I think Ford Zetec was
one) need to have a gadget fitted to bleed oily stuff into the inlet
to keep all the valves happy without the expected petrol additives.
Apparently some get converted to LPG without the gadget and don't last
long.

I can't remember all the details though, and it could all be ollbocks
anyway...

Cheers,

Colin.

Flashlube is the stuff you are thinking of. I have it on my Volvo 2.5LPT
Prins conversion as I expect to get upwards of 300K out this engine and
every little must help.

Ford engines (and cars generally) are designed by bean counters. If
they can save 0.001 pence on the price of the material to make a
valve,then they will.
Zetec valves are marginal when run on petrol without ever going near
LPG.
There are a few cars around of a bit higher design quality which direct
the incoming petrol onto the back of the inlet valves, using the heat of
vapourisation to cool the valves. This cooling effect doesn't happen
with already vapourised LPG, so these engines are likely to give
problems as well.

I wouldn't be at all surprised if it's true. Some engines will need the
odd special tweak or two, but by this time most of the current engines
will have shown up the weak spots.

It's not all the Zetecs, though. Naturally, I forget which.. I think it was
the 1.6 and 1.8 that were most iffy

and yes, you can have a gadget as you describe - 's called flashlube, and
you fill it with additive stuff like the stuff you put in the tank on
leaded-only type cars running unleaded petrol.

Flashlube is the stuff you are thinking of. I have it on my Volvo 2.5LPT
Prins conversion as I expect to get upwards of 300K out this engine and
every little must help.

Hmmm - and how is the flashlube actually delivered. My understanding
is that it needs -ve manifold pressure to pull the flashlube into the
manifold. As you have a turbo surely the flashlube delivery is gonna
be a bit intermittent?

Ah, I see the lpg group is there; maybe there's not much traffic.
