You're in IRAQ, it's really hot there.On the cap of my 2017 mustang gt it says 5w20 but recently I’ve heard that the 5w50 is better, any thoughts?
5/20 streetcar or once a year on trackHey

Good post.5/20 streetcar or once a year on track
5/50 racecar or dedicated track car.
Same here, switching over to Amsoil 5W-50 in my car for the added protection since I will be adding boost. Have been using Motorcraft 5w-20 for the past 4 years.Can I still go with 5w-50 even though the car is daily drive.. for an extra protection for the engine?
That's not true, since you always going to have cold starts... unless you never turn your engine off . A 0/30 oil is always going to lubricate quicker than a 5/30 oil when engine is cold. But yes, the hotter the ambient temperature, the less the difference. That's why I switched to M1 0/30: less engine wear at start up, due to quicker lubrication, which also should keep the darn phasers happy.The first number, 5, is somewhat irrelevant if you don't have cold starts.
Define cold? The difference is small above freezing temps. (0W vs 5W). Today I am starting my vehicle at -26C with 5W30. 5W is a common grade up here. I wouldn't fret over it.That's not true, since you always going to have cold starts... unless you never turn your engine off .
