    Oil Q.

    I've had the head gasket done in Oct/Nov so Vauxhall obviously changed the oil etc at the same time. Just looked and think i could do with a top up but dont want to buy more oil if i have to.

    I used to put Mobil One 0W40 Fully Synth in it, I have bought Castrol Magnetec 10W40 to do next time and i put Halfrauds Semi 10W40 in my Cavalier 1.8.

    Can i use any of these to top up but i dont want to do any damage to my engine if i cant mix them. Just trying to save a bit of cash after £580 on the head and £330 on a manifold.

    Ta very much.

    Personally Id say use some Vauxhall 5w30 - £18/5ltr on tradeclub.... £8 for the 10w40 semi stuff.

    Dealers would charge about a tenner for just a top up (1ltr or so) so easier just to get a new bottle instead

    mixing wont be a problem

    You can mix all types of oils with no problems (except race specific ester oils).

    Even put Fully Synth with Semi or 10W40 with 0W30?
