I can't speak to GM's system cause I quit fu@king with them decades ago due to maintenance issues. Same reason I choose the Z over the Corvette. To me saying GM and better is like saying Lawyer and honest. It just doesn't go together. Toyota's been running their D-4S system for 20+ years. Between two vehicles I've racked up around 150K with no issues and that's with 1 year or 10K OCI.
Cool man, I appreciate your uneducated & biased option. Thanks for admitting you have no clue what you're talking about.

So, some engines are a bit looser than others. An engine that puts a few ounces into a catch can between oil changes, is headed for heavy carbon buildup on the intake valves on a DI engine.
It might take 40,000 miles to sap more than 5-6 hp, but it will happen.
Most likely you can assume even a tight engine will have a fairly thick coating of carbon by 100,000 miles.
Emissions standards today won't tolerate much blowby during the required mileage interval. But track use and frequent hammering to redline, will push the rings to their practical limit.
Most people rarely shove any engine past 5,000 rpm so things like catch cans are not worth messing with. For the rest of us with DI systems - even without boost, it's just added prevention with no downside.

That reply speaks volumes to not only your technical ignorance but your social inept when someone disagrees with you. You sound really young. It's not your fault. This is what happens to people who lack original thought and get all their answers from Google/AI. Do yourself a favor and call someone to help with your low self-esteem and sensitivity issues.

I only tend to use Shell V-Power for my IS 500 due to my D-4S system (port/direct injection).

LOL! Couldn't be more wrong my man, but good try.

I love when a 30 year old uses big words but can't get to work on time. Good shit.
