Answers :

Castrol 20w-50 in summer and 10W-40 in winter, is best in my opinion.
It is high detergent, to remove sludge.
The thinner oil, like 5W-30 is only for better mileage, but cause piston and camshaft wear.
5w 30 is the best oil you can possibly use especially when you're talking synthetic such as mobile 1 ..if you look in the manufacturer's book of specifications it recommends using 5w-30 all year round
