I refer the honourable poster to my earlier answer re accurate mileage records. I delivered it to the dealer and signed off the log book. There was 30 miles more on it when I picked it up
I would query whether the 30 miles was done _after_ the service, or why do the test drive _before_ it.
I am sure I recall adding 10% petrol to diesel in the depths of winter to prevent waxing, in the days we had winters. That would be two gallons to a tankful.
======================= I meant 'query the need for a 30 mile test drive'. In your position (with your accurate record-keeping) I would make the point very strongly that someone in the dealership has made some improper use of your vehicle and abused your trust. It seems to me that modern test equipment has largely removed the need for test driving of any kind and any explanation they give should be treated with suspicion.

Apologies, a long day (and my better half working nights at Grangemouth) gave my post a shortness which was not intended. I wanted just to expand on your point about the 30 mile drive. I only managed 1 mile after the service, so how did they manage 30?
Especially since the 30 miles _must_ have been done before the service.
===================== I wasn't taking offence - just clarifying my meaning.
I would add that if the worst happens and legal action becomes necessary your accurate records will carry much more weight than any contrived explanation the dealer may produce for a 30 mile journey done without your express permission.

Yup, I used to do this too (but my diesels never had such a large tank...).

Not a great night for that...
Cicero ( snipped-for-privacy@hellfire.co.uk) gurgled happily, sounding much like they were saying :
Not at all.
Modern test equipment will log any faults that the engine management picks up, sure, but it won't pick up the vast number of OTHER issues that can occur in all the rest of the vehicle.
Keith ( snipped-for-privacy@blueyonder.co.uk) gurgled happily, sounding much like they were saying :
Modern diesel has plenty of anti-waxing additive - and modern common rail diesel pumps really do NEED the lubrication of diesel fuel - petrol's used to wash parts clean of oily residue for a good reason...
Ask for the parts they replaced. I bet they've already been thrown out.
We were somewhere around Barstow, on the edge of the desert, when the drugs began to take hold. I remember Keith saying something like:
It's utter bollocks. The diesel and petrol are entirely miscible and you also have the mixing effect of the fuel return plus road shaking. As you surmise, the garage put the petrol in.
Would it not also take a fractional distillation column?
That depends on the amount of petrol in there, I've picked up cars from near motorways, that have filled up at the services, quite happily run down the motorway for hundreds of miles on a petrol/diesel mix, then only cut out when the engine returns to idle at the exit junction.
Hmm. Modern stuff, or older stuff? I've not heard of anything remotely modern in the engine department liking running on any petrol whatsoever, however I don't know of somebody who's put just three or four litres into their diesel. Usually the majority of the tank contents are diesel... which is where it gets expensive.

We've had between 1 and 10 litres of petrol in the tank at least half a dozen times over the last 5 years before realising. Filled it up with Diesel and carried on regardless. I added a spoonful of vegetable oil as soon as I'd got home (I'd read on the net it would help counteract the reduced lubrication caused by the petrol).
It's relatively modern (5 years old) Citroen 2.0HDi engine. Engine has now done over 85,000 miles without trouble (if only the rest of the car were as good).
I'm not sure if the manual even allows for adding petrol to stop waxing in colder climates - I'll have to have a read later.

And before anyone says anything about my other post in the group today, if only my petrol engine, which has never had any diesel in it, were as good too.
