Ripto,
If you've always run dino oil, I'd suggest you do this before you run syn:
Run one more run on 4 qts dino oil and 1 qt Marvels Mystery Oil to desludge the engine before you run the syn. I ran Dino for 60k or so before I switched to syn and when I did, the Syn pulled all the sludge out and polluted the oil something fierce. MMO will do the same thing, but it's much cheaper. You can then run a standard syn for 5K or so with no problems.

I saw a dyno test between Quakerstate and Royal Purple on a show called "Horsepower" on Spike Tv. They took a newly built V8 engine filled it with Quakerstate, ran a dyno. Then drained it and filled it with Royal Purple and ran another dyno. The Royal purple boost the engine by 8hp. Not that big of a deal but an extra 8hp just from oil. Why not?

Found a fantastic dealat Advance Auto on Royal Purple (they are running the 5 Qt. Jug of Mobil 1 and filter deal also), but it's only on 1 grade and probably not one you'd use...

As far as the switch over from dino oil to synthetic, I've always done an oil change from the dino oil to a 50/50 blend product for 3k miles, then went to a full synthetic for the next change, usually Mobil 1 and changed it every 5k thereafter. However I've recently experienced a very good mpg gain in my Grand Cherokee (bought with 61k on it) by putting Royal Purple in the engine and both diffs after using the blend for the first change. So I decided to switch from Mobil 1 to RP in the truck to see if lightning could strike twice. I've also decided to go to 6k between changes with the RP in both vehicles, which makes maintenance easier for me as I rotate the tires every 6k and can now do it all at once...

Sounds like a good deal. Kind of makes me wish I used Mobil 1 instead of Royal Purple. Oh well.

I use 5w-20 RP in the 06 Accord so I wouldn't have minded getting some for $5 a quart.
