Same with most of the crowds- Mobil 1 10W 30

Royal Purple 5W30 with Mobil 1 filter. Change every 3-4 K. The royal purple oil is awesome and I use it in all my vehicles. I have seen performance increases, but only measured by the "Butt" Dyno and increased MPG. I get it from work @ cost, so the price is not an issue.

Mobil 1 10W 30 with oem pcx filter or Mobil 1 filter. I use Mobil one on my S2000 and NSX. It works great, so I won't change that

Amsoil 10W-30 with Amsoil SDF-20 filter....with FilterMag Oil Filter Magnet.

Great oil, car runs smoother than when using Mobil 1 or Redline (used them both) gets better gas mileage......

Check out the oil journals.....it will answer all your questions.
