    Been looking at oil to go in a '94 reg Merc C220 with an M111.961 engine.

    Millers optimum choice is Trident 5w40 full syn. and quotes a 5.5L fill.

    Had a look on ebay for a 5+1L offer and there's Mannol Extreme 5w40 described as a hydro sythentic engine oil. I've researched this and its a 'hydocracked' oil where the base stock molecules are reconfigured to work better with the additive ingredients.

    As best I understand, Hydro Sythentic oil is somewhere between full synthetic and semi-sythentic!

    Never actually heard of Hydro Sythentic engine oil before.
    Sounds like oil with a splash of water!

    Its really a suitable oil for use in vehicles which use the same oil for their hydraulic systems......some suspensions, transmissions, power take offs or whatever. Its been in the farming community for quite a while.
    I'd use the Millers brew in the Merc!

    Thanks John!

    I'm Millers man myself to be honest. Just need to get the 1L to go with the 5L since the capacity is 5.5L.

    Have managed to get a 6L pack of Merc genuine 5w40 (MB229.5) at a good price.

    Here, if anyone's interested!

    That seems incredibly good value coming from a main dealer!

    Its actually had W5 brand 15w40 in that you get at Lidil so 5w40 Merc spec oil should be cold start improvement.
