    What oil to use for running in a new rebuild?

    Just rebuilt a forged CA, will hopefully get to turn the key for the first time tonight but wondering what is the best oil to use for running it in? Thanks

    Just a decent quality mineral oil, something like Fuchs Titan Formula would probably be ok

    same - used the millers running in competition oil - avoid the other millers running in oil that's thicker, it's too thick for the lifters on the CA (Petrol Pete found this out).
    white '94 s13 200sx scrapped - mapped to 1.45bar. OS giken box, garrett GT2876R, 950cc injectors, ORC twin plate, nistune. 349bhp/325lbft @ 1.3bar CA18DET
    white '96 s13 180sx - type g with more kouki bits - RB25DET, GTR steel twin turbo conversion, RB26 crank & rods. 2.6L VVT twin turbo, SR20 OSG box, OSG STR twin plate clutch, Z32 ECU w/ nistune.

    current status: 180 a bit broken but to be repaired.
