From engineering explained He says you can generally use lower first number, and higher on the second number and it wont be terrible for your car. So for high performance vehicles thicker oil may be better (i.e. 40 instead of 30).

It's a good oil. 5 Star(100%) rating on website from 7 people. I generally think Castrol is better than Valvoline's, but its just personal opinion.

Its full synthetic so higher cleaners, additives etc. than a regular conventional oil.

Castrol Edge 5W-40 A3/B4 Engine Oil
Castrol EDGE 5W-40 engine oil A3/B4 with Fluid TITANIUM is the natural choice for drivers who demand maximum engine performance from today's modern vehicles requiring a high level of protection and higher performance oils. Today's engines continually push the boundaries of technology and engineering. They are smaller and ultra-efficient, without sacrificing performance. Advanced engines challenge the oil with increased pressures. These intense pressures cause friction, which can waste up to 10% of an engine's performance. Castrol EDGE 5W-40 A3/B4 is an advanced full synthetic engine oil suitable for use in automotive petrol and diesel vehicles where the manufacturer recommends ACEA A3/B3, A3/B4 or API SN/CF or earlier specification 5W-40 engine oil.

Castrol EDGE engine oil with fluid Titanium has been specially modified to transform its physical structure to be stronger under pressure to keep metal surfaces apart and reduce friction. For those that demand maximum engine performance whilst requiring a high level of protection you can trust Castrol EDGE engine oil to outperform their competition. Independently tested at the highest standards the Castrol EDGE range covers petrol and diesel passenger, light commercial and naturally aspirated or turbocharged applications so you can be assured of finding the right Castrol EDGE product for your vehicle.

    I use this in my diesel Pajero and have found it to be a very good oil. The pajero runs smoother, and much quieter than other oils I've tried.

    It's really a bargain. I bought it a month ago which priced $68 at that time.
