    Default TD5 oil question

    My Td5 D90 is in-between service intervals but has been working hard lately so I'd like to do an oil + filters change.
    I would normally take it in to my indie but since it's just oil I'll do it myself.

    Is 10W40 the the correct oil?
    Fully synthetic or semi-synthetic?
    Going into winter now, is 10W40 fine for cold morning starts or will 5W40 be better? (I have read previous posts in this regard but am concerned about a noisy engine)

    Would appreciate some guidance

    Find out what your indie uses and stick to that. I think it is better to stick to a certain type of oil and not alternate the whole time.
    Personally, I use Fuchs 5W40 synthetic. I supply my own oil for services.

    The best choice is to use a fully synthetic oil as to meet the temperature chart and choose one which is specified as suitable for EUI/PD engines... and those are mostly 5W40

    15W40 is not even in the temp chart for the Td5... IMO it's completely unproper for it

    In your opinion and Land Rover but hey we have clever guys on here.

    My Td5 has never had anything other than 5w30 under warranty and Edge 5w40 from 100k and going strong at 205k now.

    Stick to what the person who designed the engine says.

    I think you are comparing Europe temp to our temp down here !! It barely goes to minus 10 degrees , IF you are lucky
    Come visit during the winter , you will be surprised

    Nearly forgot , mine has got 260 000km on the clock . Bought from my son at 140 000 km

    I'm not comparing regions, that temp chart covers all the world cos 5W30/40 are good from below -30 to above +40 and the thickness of the oil will not help when the engine is hot anyway, it's mainly for cold start...IMO if the engine is noisy it must be fixed mechanically not filled with thin grease

    15W40 is the wrong oil for a Td5 but each to their own.

    As mentioned most of the wear is on start up so thicker more equals more wear.

    I based my decision on 5W40 on what Land Rover said,who built and tested the engine. What research or testing did you do to reach the conclusion that 15w40 is the one to go for?

    Don't only look at the grade, look at API as well, most of these fully synthetic oils are API C.F., this is 2002 standards, the latest standard is CJ-4, which is better suited to diesel engines. Ideally you'd want a 5-10w40 with a API CJ rating...I don't think they are available in SA. Delo does have a product that meets these specs 5w-40, synthetic, API CJ-4.

    I dont know about that API thing but there are oils on which is specified that they are designed for PD/unit injector engines and that's what the Td5 is so IMO if it's something like this https://www.opieoils.co.uk/p-147529-...ngine-oil.aspx it's the best, see it's description... i've checked some oils with similar specs and all were API-SN/CF or SN/SM/CF

    If it is wrong , it is wrong .

    No , I did not do any testing ! Just using it for a few years and done more than 100 000 km . That about sorts it for me !!

    Not cold at all. In winter the Atlantic is warm and my house is 200m away so close enough to feel the effect. My garage is insulated and sealed, with tiled floors. I would reckon it never goes below 10 degrees in there. It's not Isuzu loud on the thick stuff, but the difference is very noticable.

    Took your advice and contacted my indie. Did my oil change with the exact oil that has been previously been used.

    Thanks everyone
