s13 blacktop question

I just dropped the s13 blacktop in my car, and was wondering what oil is recommended. Thanks for any help.

i run a royal purples 10w30...but thats me...

Most SR20s that see hard use use 15W-50. its better for the lifters, and will handle the heat from the turbo a little better.

I use Hydrotex 15W-50... apparently they are who Mobil outsources to for use in Mobil sponsored race cars.

10-40 Mobile 1 or 20-50 good for lifters...
