No offense but that's incorrect.
As per manufacturer's specs:
Royal Purple 5w30
Visc @ 40C = 64.8 cST
Visc @ 100C = 10.7 cST
Pennzoil Platinum 5w30
Visc @ 40C = 57.5 cST
Visc @ 100C = 10.3 cST
In reality the Royal Purple is actually
thicker in both room temp and at operating temperature...
But the difference is so small, it doesn't really matter; they're essentially the same. This is unlike German Castrol 0w30, where it's on the higher end of the 30 scale (I think around 13 cST when cold)
Also, thinner oils doesn't mean you are receiving inadequate protection. A lot of new cars spec 0w20 now.
PS. I use PP 5w30 in my RSX. Great oil, cheap, stellar UOAs. (For my application)
