dkellogg, also don't be surprised if you read some printed lit that was published in 2003-4 that only 5 quarts were needed. The first manuals were wrong. and showed only 5 quarts needed. My first oil change at the dealer in 2003 was at 5 quarts. These guys didn't check the level and after the light came on I poured 3.5 of my own in. The manuals were then corrected.
