G.C. 0W-30. Worked well in both the WRX and STI. Use Super Tech filters. Always changed at 3000 mi.

5W-30, 0W-30, 5W-20...

At my first oil change at the Nissan/BMW dealer, the Nissan service chief absolutely insisted that the Zs do not come to them with esther oil in 'em, just plain old Shell 5W-30.

Now, I have a case of RP 5W-20 left from my RX-8 days. But when I asked if it was OK to use 5W-20 synthetic in my Z, the other service chief (BMW this time) practically jumped out of his chair to say "no, don't do it, you need the 5-30 in that car."

I know some of the older hands here are sick of oil-talk, but there are many of us who are relatively new to the car.

I changed my oil to 0w-30 Mobil 1 fully synthetic.. They say the only difference between 0w and 5w is the weight and that the 0w gives better gas mileage.. It's lighter so your pistons move up and down with less restriction...

I got Mobil 1 0w-30 and the Mobil 1 filter and OMG!!! I felt the difference from the start.. changing gears and accelerating feels soo much better!!!!!!

wow.. the power of synthetic oil.. soothes the soul..
