Looks like our CRV is not immune to the fuel dilution bug. The oil was in use from 8/22/21 to 3/19/22. An unseasonably cold winter was in there and lots of short tripping. We live in a small town, so most trips are 3 miles or less. What's in there now is Castrol EDGE 0W20 black bottle with a tiny bit (~ .5qt) of Castrol Euro 0W40. We're going on a road trip soon that will encompass over 2000 miles, so I anticipate a better UOA the next go around. What's interesting is I measured about 3.8qt when I drained this, which is just slightly more than the sump capacity, so I wasn't expecting the fuel dilution to be as high as as it was. And I know it's likely higher than BS's derived measurement. Poor M1 EP took a beating, with viscosity dropping from 8.45 to 5.84 and only 2.9 TBN after only 4300 miles. The sample was taken immediately after a 30 mile drive, so this is legit fuel dilution. Previous UOA was much better, but it also had a lot more long trips on it. Going forward, I'll probably do a blend of M1 AFE 0W20 and 0w30 to get the starting viscosity closer to 10.0.
