Engine Oil - New Disco, top-up advice

Hi

Can anyone advise me of what oil would be best to top-up my 200tdi Disco when I don't know what oil has been used in it ?

I don't really want to replace the oil but also don't want to add a non compatible oil.

The oil looked very new when I bought the Disco and the original seller says he can't remember what was used only that it would have been what the book recommended.

Not sure how mineral, semi & full synthetic oils would mix together.

Thanks

These are castrols recomendations i have always used 15/40 what i get for a good price from an hgv fitter

If you have recently bought this car I would strongly advise you to give it a full service. I have bought cars in the past that have supposedly been regularly serviced, only to find terrible oils and filters in place.

You can buy a filter kit from Paddocks for about £12 (air, oil and fuel) and then you need oil:

1. Engine - 7ltrs of 10 or 15-40 mineral or semi synth;

2. Manual gearbox (LT77) - 3 ltrs of ATF Dexron II or III;

3. Transfer box and diffs - EP80-90, 6 ltrs in total. 1.7 for each diff plus 2.3ltrs for the tranny box.

4. Cooling system - 7ltrs of std engine coolant

5. Clean out the fuel sedimenter.

If you do this yourself you will be setting an excellent baseline from which to go forward.

Agree with the above but if you just want to top it up buy anything as all oils are compatible with each other these days.

Any oil is better than no oil
