wrong oil

no damaged what so ever, especially over such a short distance. Years ago there was no such thing as a diesel engine oil or a petrol engine oil, it was just a choice of castrol or duckhams.

I'd be surprised if it's made much difference at all. Most engines these days will go in a petrol or a diesel engine - you rarely see any with less than A3/B3 and SM written on the packaging. If it's a direct injection engine (ie. HDI) he should be using oil that's graded as B4 at least.

On the other hand, some engines can be very fussy about what oil is used - VW extended service engines will complain if you use the wrong oil and demand a service early. The correct grades for the oil will be listed in the car handbook, including manufacturer specs (VW specs tend to be

500.something or other, and oils will have what manufacturer specs it meets printed on the packaging). If I were him, I'd run the car for a week or two (500-1000 miles) and then swap the oil and filter for a diesel specific one *if* the oil he's bought doesn't meet spec, and treat it as an engine flush. If it does meet spec, there's no reason for it to not stay in there. Even in a turbo diesel I'd expect the oil to work fairly well - turbo petrol engines reach much higher temperatures than turbo diesels. The main difference with the diesel oil is that it's capable of holding more crap for longer, as diesels black their oil much quicker.

One thing you haven't mentioned is whether he's put a sump full of oil in there or just a pint or two. If it's a pint or two, I'd be even less inclined to worry, providing it's not a brand spanking new super high tech extended service engine. I suspect it's not, as you shouldn't really need to top up oil in a new engine. If it's something older like a non-turbo XUD, I'd be inclined to not worry and leave it in there. Oil is oil is oil as long as far as I'm concerned for engines like that - they're not high tech, and if they're leaking, it's going to be pretty dilute after a couple more top ups.

Thanks for the reply, He gave it a full oil service which was filter. and 5lts of oil,and air filter also diesel filter.so i have done the drain off and left it over night with the drain plug out to get most of it out,and today we are going to put Diesel oil into it and replace the filter aswell today when he gets out of bed and comes round.Thanks again for the replys.i will show him the replys.

Did he have to be drugged to stop him buying petrol engine oil again? ;)

No i think his wife will be doing the shopping for the oil and parts from now on ahahahaha

Or nice cheap Comma re-refined if the engine was old and knackered (which in the case of a 1954 Ford Popular was around 30,000 miles).

Oh yeah , forgot all about the trusted comma oil, i must admit i did use that quite a bit, never had any problems with that stuff either GGJ

i think engines were much more forgiving in those days. I had a 1954 Bedford CA minibus that drank oil. Every month or two the oil light would start to flicker and I would pour in another gallon of Comma. If it hadn't been so cheap the vehicle would have had to be scrapped. In those days of course nobody knew anything about pollution or being green.

A friend of mine used to leave a drip tray under his Marina and pour the contents back into the engine. I think it was laso his marina that had an oil leak onto the exhaust manifold. Rather than fix the leak he diverted one of the washer jet pipes so it squirted onto the manifold and extinguished the smoking oil.

I think someone is getting confused here with fuel. Yes, put petrol in a diesel and the s*1t hits the fanblades, but putting a petrol spec oil in will make no difference over 4 or 5000 miles. Certainly no need to do a panic oil change.
