Oil Capacity Rb25

[`nigno]

Hey all, after performing a search I found results for oil capacity on rb26, rb20, rb30, diffs, gearboxes and everything BUT an RB25. Ive got a series 1 with a genuine GREX relocator kit + cooler. Wondering how much oil I should expect to put through this thing, wanting to do a full flush + change and filter job which is no big deal.

I was thinking if I bought 2 x 4L bottles I Should be fine, but I really dont want to overfill after the flush n be blowing shitty smoke for weeks.

Any help is greatly appreciated, if youve got any recommendations for oils would also be appreciated, 500hp street/track that cops a bit of a hiding, so I need something decent n dont mind spending the $$$ to ensure it doesnt go bang

Cheers,

James

well first need to know how many k's on the engine to know what type to recommend. also is it just fresh from a rebuild (ie. 0k's on rings) though consittering a skyline should take approx 4.3L when fully flushed and then sorta work out the aprox capacity of the lines and cooler and addem together obviously. but id say if you bank on needing about 5-5.5L should be safe,

If you just drain the pan and filter change, 5L will be enough.

If you want to mess around trying to flush the oil cooler and stuff (waste of time, cause more problems with flush agents) you may need more.
