Oil change 10/40 --> 5/30

    Bought a nissan note 1.6(hr16de) petrol for wife and going to service it.

    It has 90k kms on it and I am planning to change all fluids/filters/plugs/belt etc per service schedule.

    Car has a full service history from windsor Nissan but all receipts shows they used 10/40 semi synthetic oil instead of 5/30 fullly synthetic oil for years.

    Queried with Windsor and they said it is 10/40 for 1.6 notes and 5/30 for diesels.

    I am quite strict about using correct spec oil in my cars but I am concerned a little bit about changing the spec after long term use in meaning of potential gasket leaks due to thinner oil.

    What do you say DIY community ?

    Did you try putting the reg no into castrol.ie to see what they recommend.

    Nope until now. It recommends Magnatec 5/30 A5 or Edge 5/40

    All Nissan forums were pointing to 5/30 and I think manual says 5/30 as well.

    I am pretty surprised about main dealer insisting on 10/40 and I wonder if they use the same spec in quasqai 1.6 petrol engines as it is the same engine.

    That is very strange alright. I'd use 5/30 magnatec if you're using a fixed mileage/ annual service interval.

    I wouldn't worry about it. The same thing happens with the vvti engines in Toyotas. The books says 5w30 but the dealer uses 10w40.

    Don't all dealers just use the same 10/40 in everything?

    On a higher mileage car 10/40 instead of 5/30 may have the advantage of reducing oil consumption, but I wouldn't call 90k kms high.

    They (should) use the recommended oil specs by the manufacturer of the car.
    As far as I can tell it's 10W40 for HR16DE, 4.6 litre capacity

    We always used 10W40 with the same spec for all the vans that came into the workshop. It's kind of crazy really :pac:

    Why is that though? surly you should stick to the recommend oil grade suggested by the manufacturer?

    If you look at most cars handbooks they state several oil grades, for different conditions and temperatures.
    usually lighter winter weight oils are designed for fuel efficiency and not necessarily better performance.
    so the example given for Corolla's 5w-30 is specced for -30°C to +38°C+
    but you could also use 10w-30 from -18°C to 38°C+
    and in fact 20w-50 is also listed from -7°C upwards
    So in reality you could use a whole lot of different oils including 10w-40 which is both affordable and easy to find.

    It doesn't say it in the book but 10w/40 is what a toyota dealer will recommend. 10w 40 works better in those vvti engines in my experience.

    Also a heavier oil will reduce oil consumption.

    Not necessarily. OP, use a decent 5W-30 Group III synthetic.

    It does on the first generation vvti engines and on the mk1 focus. I can attest to that.

    So that would be heavier than what - the 10W-40 specified in the contemporaneous manual?

    How is 10w-40 suiting the general?

    It isn't. I use 5W-30 Group III synth, contrary to the now 17-year-old documentation. That's sort of my point, you see.

    Your old yoke would run on super universal tractor oil 15w-30 sure.

    You mean 15W-50. And I thank you for your technical input, I shall ensure it gets the consideration it deserves. :D

    No 15w-30 as I said. The general would blow its load on 15w-50.

    That's for damn sure. 15W-30 is obviously for yokes that never cold-start, yeah? :D

    I believe the new Honda's use a 0w-16 which is a new standard that counts down in 4's instead of fives specifically to denote the lower viscosity oils.
    Not sure about the Insight.

    Only the 1.6 diesel requires the 0w-16 Green oil.
    About a year ago Honda pulled the plug on 10w-40 and now recommends 0w-20 for the petrol engines (except Type-Rs,S2000 etc. which is still 5w-40).
