Difficult to know what if any damage may have been done, particularly to the DPF. You may wish to Google to find out if the accumulation of sulphur, etc., in the DPF is cumulative/permanent or if it disperses once the source has been removed. Another option would be to call Castrol & ask their technical people whether use of that oil for that period of time would be an issue - most suppliers like this have good tech advice available.

I wouldn't be so willing to accept their mistake and their verbal acknowledgement/admission of fault. You gave them every chance to check their work and the product used in your car was correct at the time. Whilst not wishing to start a thread of "dealer bashing", IMO, it is totally unacceptable for a professional franchised dealership (or any workshop for that matter) to make such an elementary mistake in the first place, let alone not checking & correcting it when you raised the issue.

I would ask the Service Manager for written confirmation of everything that they did, including his assurance that no harm was done and that they will cover it if any issues or faults which may appear at any time in the future as a result of their error. If they won't do that, I'd write a letter to the Service Manager outlining everything they did and said, plus everything you did to try to alert them to the issue. I'd finish the letter by requiring their written acknowledgment of the facts as set out in your letter and their assurances. I'd copy the letter to the Dealer Principal and MMAL.

Also worth noting that, if the PS is anything like the Pajero Gen 4, in which about a litre of the oil oil remains in the oil cooler system & isn't drained in a normal oil & filter change (even more if the filter isn't changed). I'd be asking about this and probably insisting they change it again now (incl. filter) at their cost to ensure more of the incorrect oil is removed. In a Gen 4 there would still be approx. 10% of the incorrect oil still in the engine - a second change would reduce it to approx. 1%. (but I'm unsure how much remains in a PS).

I wonder how many other Mitsubishis have gone out with wrong oil !! and how the hell can a service MANAGER not know what oil to be used ,

Unfortunately, it is because they are a MANAGER, not a mechanically skilled tradesmen. The days of skilled workers moving up through the chain are long gone, now it's all uni degrees and ass kissing, performance quotas and profit margins. No mechanical understanding required or cared about.

To O.P, I would be keeping all receipts on file for future reference, but I doubt long term reliability will be affected.

Thanks ALL!!

Cheers! for all the advice guy's. I have e-mailed Castrol and am awaiting their reply before going any further, I don't think any damage would have been done either but have an uneasy feeling about the whole thing. i''ll let you know the outcome.

Thanks Jim

Our Mitsubishi service centre last 2 managers were skilled Mitsubishi Technicians ... wouldn't go else where

When we first bought the vehicle there was an unskilled manager of which they flicked in 6 months

... tried to ask us if the Challenger was petrol or diesel

I'd be asking them to change the DPF straight up ... damage is done

Thanks for the input, so the DPF and getting it replaced, is this something you are sure of or have firm mechanical knowledge of. i'm sure they won't replace anything without a firm fault. Jim

I ran a NS diesel for 140000k using Delo left over from my boat motors never had a problem. The only difference is one oil is LOW ash the other isn't fact is if your engine isn't using /burning oil nothing will be going through you DPF so don't worry .

it may be okay, it may not be okay ... it may last the warranty period but after that it's going to cost you a small fortune ... oil manufacturer's put a lot of money into research for a reason

and car manufactures' warranty is written and worded as such that buy putting wrong oil or parts in/on to a vehicle may void your warranty ...

I agree with spot01. A good comprehensive written record of the event/mistake between the dealer and MMAL and yourself. In addition, I would be requesting that MMAL advise you whats their thoughts are on the matter and not just take the word of the dealership.

Like some have said i doubt there would be too much issue with what has occured right now based on kms etc done with wrong oil but and a big but..........it may have put an increased amount of soot into the dpf which in time may block and/or create problems prematurely.
