just drove my brand new sunlight silver rx 8 home from the dealer about 2 hours ago. its all i expected from this car. i just have a couple of questions. what is the best oil, brand and viscosity, to add to my rx? and is it worth checking the oil level every time i fill up?

Your car will burn more oil on the first couple 1000 miles. Check every couple fill-ups. You can't go wrong with major brand 5-20 dyno oil.

thanks for the quick input. i want this baby to last a long time. its the coolest thing ive ever driven not to mention costing a pretty penny. still worth every one.
