Just wanted to share my Oil Analysis report from Blackstone Labs that I've been doing almost since new (missed @ 20k miles) The first 2 oil changes were done at the dealer with the included maintenance when I bought the car new. They "forgot" to take the sample when I asked at 20k miles. The last 3 were done by myself using Mobil 1 Advanced Fuel Economy 0W20 and 04152-YZZA6 filters I bought in a 5 pack on Amazon a few years ago when the free maintenance ran out and I started doing it on my own. 15-Prius-55k-oil by amarino posted Jun 22, 2020 at 1:25 PM
I was idly thinking what they'd say if I submitted an oil sample, with my change interval. Maybe "c'mon, this is new oil right?".
Yeah mine still drains black as ink, but a lot less nasty looking than other cars I do. Lucky to see 4K kms (6 months governs), and with COVID even less.
I'll be changing our Primes oil going forward now, so we'll see how it looks knowing that 70% of the mileage is EV. My bet is it'll look similar to yours. At the rate I'm going now though, it's looking like one oil change a year and it might be before 10k miles.
