    That is a motorbike forum and they are referring to bikes which have a smaller sump oil surface area than a car and so any expansion would give a higher reading on the dipstick than on a sump with twice the area.

    In any case it appears to hardly matter.

    Read the quote from the manual in reply 8. Thats what matters, not some opinion on a more or less irrelevant forum.

    I bet the guys on the Moto Guzzi forum think the same thing re equivalent posts on VWW! Signing off as the below is eerily familiar;


    In the meantime, disregard the Moto Guzzi factor and read the thread....it actually related to the OP FFS!

    "Density (T) = Density (15 C) - beta*(T-15) where T is the temperature in °C, and beta is approx 0.0006 g/cubic cm/°C.”
    The source of this information from Shell is:
    R. Larsson, P.O. Larsson, E. Eriksson, M. Sjöberg & E. Höglund, "Lubricant Properties for Input to Hydrodynamic and Elastohydrodynamic Lubrication Analyses", Proc. Instn Mech Engrs, Vol 214, Part J, pp 17-27
    Earlier investigation led me use a 15.5°C (60°F) specific gravity of about 0.890 which is still consistent with this information. Using that yields:
    Temperature, °F53268104140176212248 284
    Temperature, °C-15020406080100120140

    Density, lbs/ft356.6856.1255.3754.6253.87 53.1352.3851.6350.88"

    At 4.7L for a EA888, checking hot vs cold will result in imperceivable results.

    Apologies to the Moto GUzzi forum I meant the subject was rather irrelevant to the OP's question as the 2 types of vehicle were very dissimilar

    As the edit function is playing up I will clarify what I meant

    The increase in the level of hot oil in a car sump which has a larger surface area than a motor bike will be a lot less and therefore of less significance in the scheme of things.

    I have the same scenario as minke (OP). And the same engine (EA888 ).

    Checking my oil cold gives a lower reading on the dipstick than when checking warm, after the recommended ~5 minute wait. Probably around 3ish mm on the dipstick.

    Therefore if i was right at the high mark when cold, i would be ~3mm overfilled when warm. That's why i check when warm.

    I appreciate the technical nature of this thread discussion, but given that the oil level should not exceed the max mark or the min mark, then if the oil level does not exceed these two extrema ( and for safety, let us say not below the mid point ) then does it really matter if the reading is taken hot or cold ?

    As a point of reference, when new, my 125TDI came from the factory with the oil at the max mark when I checked it cold. It has now travelled 12500km and the oil level is down 2mm.

    Couldn't agree more.

    As long as you check it the same way all the time it doesn't matter.

    I just got my GTI back from service this week and they used about 4.9 L. Checked the dipstick and it is on max, but there is oil right to half way up the stick. Anyone else have this??

    If it's just a smear of oil up the stick then don't worry. If it's solid then they have overfilled.
