Low Viscosity does have advantages, it lubricates better and faster at start up, its circulates faster, you can build an engine with tighter clearances and use a thinner oil and not lose wearability but gain durability, many races have found this works and have switched to lower viscosity oils from the 50 weights they used to use. I have several japanese cars that use a 5w20 oil all year round and get nearly 35-43 mpg and the engines last with the highest mileage engine at 245,000 miles and it runs like its brand new….I use a Castrol Synthetic blend and oil changes at 6000 miles and Ive had very good luck with Low viscosity.
