Has anyone used a 20K oil and changed it at 20K and done testing on the oil? If so, what were the results?
I have a 2010 Honda Insight that I've started using extended mileage oils on (i.e. Mobil 1 15K and 20K, changed at 15K and 20K respectively) since around 90K miles and it's now up to 225K.
I started driving a 2015 Prius C and at 168K miles want to try the Supertech 20K 0w-20. I plan to run the oil to 20K miles and then do Blackstone testing on it.
About 90% of my driving is highway at 45-60 mph for around 30 miles each trip.
