In something like the 4C, I'd simply double my oil change rates, never go below 5w and do as I do today: Actually drive it responsibly as part of the warm up cycle, instead of idling like a clown (Porsche owners gotta get her warmed up, because their uncle had a Porsche and he said, blah frigging blah) and stop taking short, relaxed drives, and understand this is not an issue in cars that get driven very few miles. What... we gonna drop another 100 bucks a year on fresh oil?
Oil tests are 1/10 of a story. 9/10 is the owner. Warm up cycles done wrong, excessive cold running, cheapskating, garage-queening, and other human factors hurt most.
In a mass produced 1.5 turbo in cars and suvs meant to go often 20,000 miles / 32,000 km per year and for owners looking to go what used to be an easy 100,000 miles / 161,000 km, it is a big ass deal.
I can do 1500 mile oil changes if needed. I drive a months worth of miles over six months. But mass produced cars and oil dilution is the real issue. If you eliminate the variables Honda controlled for in their 'fix' ... and you're left to drop 100 bucks per year more on oil? I mean, you don't even need to pull the filter! Pump it out and replace it!
Ergo: a 4C oil dilution problem (if real) means I will spend $ on just oil, to double my oil change rate; I will pump it out, leave the filter and call it a day when I add some fresh oil. I might not even dirty my hands.
