I've never heard of that oil but it looks like it is made by BP Australia.
The German made Castrol 0W-30 is great oil but I am not sure if you will be able to find it in Kuwait or not. It should say European Formula on the can and but will definitely say Made in Germany. I've been using this oil for a while and had an oil analysis done and at 9K miles on the oil it could have been run longer. And these results are typical.

ha ha maybe it was at one point in time but I've seen a lot of stuff saying their oil went downhill a few years ago. They still advertise it like the formula never changed though. The Castrol 0W30 is a thicker weight oil when compared to a Mobil 1 of a similiar grade if I recall correctly. If you're spraying you are putting a lot more fuel into the oil because of the rich afr so it will need to be changed sooner. A lot of guys that spray a lot just run regular "dino" oil and change it more frequently.

A good 0-5 or 10w-30 should be fine as long as your car sees normal operating temps. Running nitrous really won't affect oil weight. Mobil 1 synth changed their formula after Exxon bought them out and does not use true base IV synthetic stock any more so it is not as good as it used to be. I run Castrol Euorepean (German) Formula 0w-30 in my car with very good results. It is a true synth and comes stock in BMW's and Mercedes now.
Having said all that if your temps get really hot the thicker 40weight (2nd number) may be better. I am not a Mobil 1 fan any more but they do make a 0w-40 "so called" synth now IIRC. If your dead set on 15w-50 Rotella-T is tough to beat.

^ agreed on the rotella. Not sure about the 0-5 though 
Weather my oil needs it or not I try to change every 3k miles. I just run what GM recomends 5w30 mobil 1. Figured its recomended for a reason so why even worry about it. Whatever weight you decide just periodically check it and change when needed. Especially when using n2o since so much extra heat is generated. Good luck
