Hi There , can someone please recommend the BEST oil to put in my 2021 6.2 with 66000kms on the clock (out of warranty). Climate is mild (New Zealand) and i do a reasonable amount of towing. Are we saying go away from the recommended 0w-20 and use 0w-40 or 5w-30??
My LS1 5.7 Holden (2000) just clocked over 420000km on 10w-40 changed every 10000kms engine never been opened....i want the truck engine to be the same!
