Yes it's seven, just changed it on Sunday. The oil is ow40 Mobil 1 synthetic filter # is m1204. You can also use pure one #L14670 which is what I used. I saved the old filter it says factory installed on the bottom, yes I'm obsessing.
2006 SRT8 Silver
Good point Amant. I too plan on saving the original "factory installed" oil filter. I think I currently have one of the most documented SRT-8's possible.
Here's some of the data I've gathered from various sources:
Overall build number: 54th
In-service rank: 13th
USA In-service rank: 12th
Build dates, and build times
All original papers, including factory printouts
Copies of all brochures
Original dealer order
follow-up documents mailed by Chrsyler, including surveys and owner magazine.
Chassis dyno results with about 1000 miles (will add another this fall when it gets cold out)
Signatures in engine bay from line workers at assembly plant
Other stuff in the file I'm sure I'm forgetting.
(and thanks to those of you who helped me assemble this data - you know who you are!)
