Serious question, if it's been asked, I missed it...
In the case where one has an engine that dilutes oil (lets say a D1G2 5W30 with a starting 100C viscosity of 11.0) out of grade, would switching to an oil with a higher hths value but the same 100C viscosity stay in grade longer or must one look at a higher 100C viscosity, even if going to a xw40 if need be? Or, could both be required?
I'd either use an oil with both higher KV100 and HTHS or just
accept that viscosity loss if it happens within reasonable limits.
What (percent) fuel (and water) dilution are you talking about?
