If your considering one of these oils, Castrol Magnetic(5w/30 ?)might be a good choice for your HEMI due to it being "thicker" and might be able protect your engine much better in higher climate temperatures like you have in your region of the world, idk.
As
@Burla and others noted in thier comment(s), any oil that can help to reduce your HEMI tick is the ticket. Imo, no one here in the RAMforum is going to know and be able to exactly to tell you to use a certain specific brand of oil weight/viscosity to resolve your issue ... that is on you and what is readily available in your area.
One thing that is for sure and certain, every HEMI doesn't react the same to any one type of oil and filter due to how they are used and the climates they operate in, if they did we would all know exactly what oil and filter to use and this thread would diminish, lol.
Maybe having an shorter oil change interval with whatever oil and filter keeps your HEMI healthy, idk.
My 2017 HEMI under 50,000miles hasn't developed the tick ... yet ... maybe, because I performed oci's(@3000 miles) from day one ... and possibly have so far, have gotten lucky changing from (PP 5W/20 winter months and 5w/30 summer months) on the first try with Red Line 5w/30. So far, all is good.
Anyhow, keep on keeping on and give whatever oil/filter combo a chance to "do it's thing" before moving onto another. To many oci's with different oils and you may never find what does the "fix".
