    Oil brand for XJ 5.0 Supersport

    I'm getting the oil service done and I was wondering what oil brand is best. I know its 5/20 but I was wonderingwhat's the best for these motors.
    I've had a look and this seems good.

    Anything that meets all the specs.

    i personally use GM oils because it’s dirt cheap on trade club, but that’s in my deseasal that is a different spec to the 5l SC lump

    Eh?

    The SC Petrol oil is different to the Diesel oil? Yup, I know...
    The GM TC oil is different to other oils? Nah.
    The Castrol oil is different to everything else? Probably not.

    So the manual recommends SAE5W-20 engine oil meeting WSS M2C925-A only for the V8 motor. I used Castrol’s matching spec with my atmo v8 with no problems.

    The diesel oil is different being SAE 5W-30 spec WSS -M2C934-B only if it uses a particulate filter. IMHO the type of oil is far more important than extra changes between recommended intervals.I have also used fully synthetics for decades and swear by them provided they meet the specs.
    the PSA diesel is a different animal to the Ford Mustang motor and I would look at Fords recommendations if in doubt.
    I’m not sure what Boys getting at but the issue is the oil spec not the brand.

    A friend of mine who is an indy and has been working on Jags for 35 years said the reason the tensioner can fail is the wrong oil grade and prolonged servicing.

    All EU soot chuckers will be DPF, not sure about rest of the world.

    I highlight this, because many of the UK online oil sellers recommend an inferior, DPF damaging oil when you pop in the reg.


    My clarification was I didn't understand markva44's comment of "very different". But, I concur with you, its the spec that matters.

    You should always match the spec (not just the viscosity spec, but the full spec) no matter what, unless you really know what you are doing. The servicing intervals JLR state are suicidal for engine protection, they are ridiculously long for marketing purposes.

    Not ever checked if the 5l V8 is belt of chain. If it is belt, the oil servicing will not impact the belt tensioners at all.

    In which case completely ignore JLR's daft service interval, and change the oil regularly
