make sure you get the "ultra" platinum, which is hard to find locally (at least for me). i've been running regular platinum full synthetic pennzoil for years on all my cars, including the LS. No issues for me and always available at walmart for under $24/5qt jug.
to stay on subject, what is the objective evidence that royal purple "cleans"?

ah ok no problem. i'm curious since i have another car with a sludgy engine and want to see what will work to get get rid of it. i pulled the pan and it was baaad, plus the valve train was pretty coated with sludge too. put in mobile 1 full syth and haven't checked it since other than oil level on the dip stick which seems ok but not substantial enough to tell if the rest of the engine is sludge-free. i try to stay away from seamfoam stuff!

When I first bought the car on whatever oil it had in it, I'll scope the car again so I can show the improvement but when I did the other cover (was not leaking at the time of the first) after about 700 miles on RP it was far cleaner

RP ATF is good stuff, their motor oil is way over priced and below average at best.

For this car Royal Purple oil is worth what it makes you subjectively feel. The warm and fuzzies could make the oil really worth the money you spend on it.
Otherwise any modern synthetic including the bargain ones that have the API starburst certification label will be far, far better than what the engineers designed the motor to handle.
