I understood that the problem with silicone sealant was not the stuff itself but the gases given off during curing (Acetic acid IIRC?). It's supposed to be pretty inert once cured but if said gases get into the induction system they allegedly cause problems with Lambda sensors.
My other thought is, I wonder what creative excuse they are going to come up with as acceptance of liability is not going to happen!
Interestingly Tesco have put a statement on their web site:
We appreciate the inconvenience this is causing some customers and can assure them that if a problem with our fuel is confirmed we will do the right thing and act quickly to put it right.
Put their fuel right or their customers' cars right? I wonder...
Nothing on Morrisons site (where my fuel came from) but I got some satisfaction in watching their share price lose a few points yesterday.
They need to make up a story pretty damn quick. They must have an analysis of what was in that fuel by now. They could have run it up on a couple of test engines in a dyno cell and logged exactly what the failure mode was.
I guess they know full well and have done for some time (maybe even since before the hysteria picked up) but the lawyers are now debating over what they can admit to.
