From what I see, the second picture shows an increasing combustion
chamber temp from top to bottom, with the top cyl looking good, the
middle one so-so, and the bottom one critical, burned out and detonated
to pieces. This looks vwery much like a cooling issue in the bottom of
the motor, possibly also a decreasing lack of oil spray to the pistons.

So take a look at the pics!!! a very close look & this um is a
"dealer" saying it's all down to the owner??? because they didn't use
the really really expensive dealer only oil???

This is the sort of damage expected from an engine that has lapsed
into severe detonation!!!



Is there an award for the simple-minded in Australia? How many times
have you won it?

The first set of photos shows a jug of oil juxtapositioned next to
ruined piston/cylinder combo. The second photo shows a bank of three
cylinders with a ruined piston/cylinder combo. The first photo does not
prove that that oil in the jug was the oil used in the engine, and
neither the first nor the second photo include any analysis by any
expert indicating what, precisely, caused the damage, other than
detonation.
