    Oil type

    i have a 2004 coupe with a Z18XE engine, i was thinking about doing my own oil changes as the dealership seems to use rubbish oil. what would the best oil be for my car in make and in weight.

    thanks in advance

    oilman recommended this for my z18xe -

    Silkolene 5w-40 is the correct grade unless the car is severly modded or used on track and seeing oil temps above 120degC. Then we recommend the 10w-50. fully synethetic.



    BUT... once you use fully syneth i dont think you can go back, unless i'm mistaken.

    Silkolene is meant to be good. It contains esters, which means it clings to the engine. PM oilman, he'll tell you all you need to know.

    Magnatec is good enough if you want something to flush the engine.

    Hard to beat Silkolene or Fuchs (same stuff). I use a Fuchs 10W40 fully synthetic in mine. I've also used Silkolene XTR 10W40 smei-synthetic and it worked well enough too.

    I use Silkolene PRO 5w - 40 and it is worth its weight in gold! (X20XEV engine)

    Darryl, just out of curiousity, how much do you pay from your oil?

    I pay £39 for 6 litres of the Fuchs SuperSyn Diesel at my wee local motorfactors. The DTi uses 5.5 litres so have to buy a 5 litre can and a wee 1 litre one.
