Not really its better for protection when hammering it.
In a nut shell:
10w40 - day to day
10w50 - spirited driving
10w60 - hard driving/trackdays
I use Millers NT 10w60, good performance so far and have recently won awards for its Nano Technology oils.
Others use Silkolene; people like Clarke (RCM) uses ProLong due to it offering the best engine wear results against other brands (might be a marketing ploy).
Swings and roundabouts, however make sure you use a quality brands and don't get cheap and cheerful brands.
Also Halfords trackday oils - don't bother results are coming out of poor protection levels.
