I was doing an in depth conversation with GROK on the known issues with the 5.3 l83 and proposed some rules to the conversation. Basically it came to the conclusion that efficiency comes at a cost. Im from the old drag racer days of carburetors, then fuel injection, then higher operating temps, etc. Admittedly I care little about CAFE standards and have ran 40wt synthetic oil In everything I own and have never once had any engine issues. We discussed the higher operating oil temps, higher thermostat temps and all of the other things they compound. Basically we came up with that 180⁰ is sufficient for moisture boil off, and the engine and oil would last a lot longer if manufacturers would slightly upgrade their systems. Ie hybrid multi port injection to keep valves cleaner like the good old reliable engines, upgrades to the PCV system and so on. The conversarion was MAKE VEHICLES RELIABLE AGAIN. How is it that I have an old 1996 nissan hardbody that literally has never had anything done to it besides a distributor replacement yet some newer vehicles spend more time in the shop than they actually get driven? My 2004 tundra has 290k miles. My 2001 tacoma has 400k miles and neither burn a drop of oil between changes and I go 10-15k Oci. Yet chevys need 5-8k oci
