i did a little research...i've read on the skylines forums - they use:Redline MTL oil for the tranny80W140 with friction modifier for the diffand mobil 1 5W50 for the engine...

i just can't find where to get that Mobil 1 5W50 oil :S

5W50 seems odd, I prefer 15W-50 in my turbo engines for summer usage...

I would run the redline for the gearbox.

For the motor, with the tight clearances the RB26 has, it's best to use exactly what it says. 7.5w30. I would use mobil1 synthetic. Or castrol synthetic.

50 weight seems kinda high if you ask me. If you have a healthy motor, there shouldn't be a real reason to run a 50.

The oil pressure is not what I would like to see, I am thinking about some 30 weight.
