HUUUSSSTTTLLLLEEEERRRRRRRR!!!! UOA ever pan out? Im torn between Rotella and RP this weekend for the 1k (little over) mile oil change. That oil test link really made me like the RP, but like you said, no idea wether it was a GV or GIII.

I'm most worried about fuel contamination with the 11.5:1AFR, so I may end up sticking with Rotella Synth anticipating that UOA's will suggest shorter OCI's. I'll make an oil thread / Saga when that time comes.
As for the Rotella vs. Royal ****... BITOG and their UOA results suggest that Rotella dino is superior in every way to RP, and the Rotella Synth is $6 more per gallon an light-years ahead of the RP considering shear resistance (most important for turbo guys), detergent quality, anti-wear package (ZDDP), avand maintaining viscosity at temp (2nd most imortant) with a simple hydro-cracked group III base stock.
I also run Rotella dino in my daily and if someone wants to sponsor / bankroll UAO's in that car, paypal the cash and I'll track both.
disclaimer: I'm a Rotella nutswinger for one reason: massive oil burn with GTX and Rotella dino stopped it completely in my daily. I run the synth in my turbo car because its cheap and UOA's suggest the best results for reasonably priced oil. I'll step up to group IV if the fuel contamination doesn't cause drama for my momma.
Closing comment: I recommend you ***** the UOA's on bitog, then go with rotella synth and a 7-8000 mile change interval backed up by a UOA at 3k, 5k, and then the change at 8k. It will last. Penzoil Platinum may be a good option too, but i believe the Valvoline synth resists shear a bit better...let the UOA's back that up for you.

this is a phenomenal read for people who are just starting to learn about engine oil.

and an interesting article on UOA's for when you demand results and not marketting:

I run amsoil i got from soflarick nice deal on a few cases a few yrs back. It works the best out of all i have tried, ie Kendal, Q, Royal purple, Mobil synth etc. Royal purple is close to amsoil but not quite as good and the others fall by the wayside with Q being better than Mobil and kendal being equal. This is in reference to oil life and overall hp loss per mile.

I guess I will give the Rotella a shot. Only experiance I have with it is in heavy equipment, and in those cases I wasnt too worried about wear or lifespan of the oil. It kept the stuff running and it got changed every now and then. Though I do recall it always looked pretty good coming out.

You can't estimate the condition of the oil by looking at the color. If anything, darker oil means the detergent inhibitor pack "worked." If the oil is black, then it means some foreign compound or chemical is processed or secured by the oil. If you took the detergent and dispersants out of the oil, and it came out clear you'd probably think it was in great shape, rather than let contaminants and free metals float around.

Rotella T Heavy Duty 15W-40 gallon, $10. I was going to go with the Rotella T Synth but it was 5W-40 and sounded like water in a jug, which bothered me, so I went with the only slightly thicker Rotella they had in stock.
I also just noticed the smell. Nothing like most gasoline engine oils Ive smelled. I guess its in the additives or stock.

Amsoil makes an oil you can drive 35,000 miles on, but for most of our applications I wouldnt recomend going that far on it. some guy even went over 400,000 miles on one oil change with the diesel oil, and the oil sample said it was still within speck of lubrication propertys for a mack.
