I have 2 vehicles both direct injected. 1 is a 2015 Acura MDX 3.5L and the other is 2020 Acura RDX 2L Turbo. With direct injection, and all the issues that come with that. I currently use M1 0/40 in both. The MDX OCI is 5K. The RDX is every 3K. Driven spirtited daily. With Nissan GTR engineer stating the old school way of changing oil every 3k miles, if you plan on keeping the vehicle beyond 300k miles which I do. I’m looking at 10/40 1 higher HTHS,
2 does NOACK matter if your on a 3k service interval? I believe a conventional oil doesn’t start to burn off in a good engine with regular port injection until your beyond the 3k mark.
A friend of mine builds LS engines, some are tracked others are not. His go to has always been a conventional 10/40.
