Casterol 5w40 A3/B4

But I switched from Casterol 5w30 A5/B5 because I was getting this noise and temps are 30+ here. Prefer the protection over fuel economy
Mine didn’t like the castrol 5w40 when I used it years ago, you are better off with total 5w40 but not the energy version
 
The only thing is for european oils, castrol is the only oil I can get anywhere off the shelf and most affordable. in conversion, it costs me 22 english pounds, for 5 litres which is pretty good for quality stuff. Everything else in that bracket is driven towards north american oil specs. Unless I go for us here really exotic stuff like motul, liquid moly, ravenol etc. I am paying up to 54lbs for 5 litres.

Mobil is too loud. I could give Pennzoil a shot? Or just meet in the middle from exotic to quality and go for premium and get Shell T6 5w40.

Who knows....

Look on YouTube and search Peter tester oils, he tests loads of oils and I use total quartz 10w40 based on what the tests say and for my climate (south of England where it never goes below -10) but you may find something more locally available to you which comes good in the test? Where abouts are you located?
