Manual says 2.5L, SAE80W-90 (above 10C) or SAE75W-90 (all seasons)

I once read the super lightweight shockproof is best and even gives a couple more hp, i never tried it because of the price and i was desparate to get back on the road so bought the cheap stuff, ill deffo try it in the future.
Im certain it was icemark on rx7club.
