Hi, I've just bought my first Land Rover - It's a 1989 19J (a 90 with the 2.5 turbo diesel engine) and I want to do an oil and filter change. I have searched for hours and come up with dozens of different suggestions for which oil to use. I live in the UK and will use it in all conditions. Can I just go to Motor World and get the carlube 15w40 turbo diesel oil?

Thank you in advance.

Don't waste your money on an expensive oil - cheap and cheerful is the way to go, but just keep up with the oil changes.

The best way forward for that engine when doing an oil change is either a 10w40 or 15w40 mineral oil. As mineral is a much more suited oil for an older engine. However you need to change the engine oil every 5000 miles when using mineral oil. Semi-synthetic can be used and will last for longer drain periods but changing every 5000 miles using mineral oil will keep your engine in tip top condition.
