    oil you should use for new vxr turbo?

    quote by courtney sport ---A 10w-40 FULLY synthetic oil of API SL classification or greater must be used. (The 5w-30 oil is too thin for this turbo unit and can cause smoking on idle)

    im changing the turbo unit to a vxr one, i just changed oil and filter last week and put in mobil 1 0/40 oil fully synth. is this still ok?

    ??????????? please say yes as it cost me £40!

    stick with what vauxhall or CS say mate
    also change the oil every 5k if you ask me as oil is very cheap
    5L of the vauxhall 5w30 costs £18

    In the vauxhall manual it says use 5w30 or higher. i've heard off quite a few guys that the 5w30 is too thin for turbo cars. mines always had 10w40 when it got serviced by vauxhall. and i've always put 10w40 in myself.

    I think that 5w30 is all well and good if the turbo is in tip top condition - if it is even slightly worn, you are better off with 10w40 as it doesn't smoke as much.

    I think 5w-40 is to thin, im on my second Vxr turbo and mine didnt like it, it leaked like hell and the noise was unbearable. Now im using 10w-40 and all is good, no noise and no leaks

    Allthough used 5w-40 for 35k on standard turbo without a problem.
