Nothing wrong with preventive maintenance at all... I have a jug of VRP 0W20 for the Rav4 Hybrid I will probably run at around 40K also.

As far as oil consumption goes, my other car , a Honda Civic with over 300,000 miles, doesn’t use a drop of oil and it did use 0w20 oil at some point unlike my other car that burns oil that only used heavier 0w30.
Just checked….335,000 miles to be exact.

Yep definitely engine dependent. I have and have had many vehicles that never burned a drop.
I expect some hurt feelings. I was always in the 5k on quality oil camp until this car. Really makes me wonder what to do on my next new vehicle as I never want to deal with this again. Boutique? Hoping ESP is the answer.
Thanks for sharing these results Glenda, and thanks for staying with it! 
Your results seem to suggest that VRP has a unique cleaning ability, especially for piston ring deposit material. It also exemplifies that you may need to stick with it for at least 4 OCI, as Valvoline claims.

Good thing you checked the oil level on a regular basis or it would have been worse and VRP wouldn’t fix that type of problem when owners let it get too low.
I am convinced some of those cars that burn crazy amounts of oil are caused by that. At least the ones driving down the street fogging the neighborhood.
In some ways, it could confirm why Valvoline doesn’t market their oils for extended drains as some engines may suffer deposits like this from extended service. Everything seems fine until oil consumption starts to increase. UOAs have limits in their usefulness to see evidence of change in the piston ring areas.
That said, it’s possible this could happen even on a boutique oil though less likely as they are formulated for extended service. It would’ve been interesting to see if Amsoil Signature Series kept consumption down with regular use prior, but all the same for ESP as the guinea pig; though by comparison is it marketed as an extended service life oil?
Why not continue VRP until you see no further improvement? Who knows, consumption could go back down to 1/4 quart in 5k miles
Gasoline is the main culprit of the ring lands getting stuck because it fills up with carbon. Gasoline, especially low-octane fuel, is cheap for a reason: it contains very little to no detergents. Personally, I use a fuel system cleaner twice between oil changes, maybe more often. It seems to help. I would definitely keep using Valvoline R&P and also use some fuel system cleaner, maybe Techron High Mileage or something similar. Red Line SI-1 is very good. PEA has a tendency to clean those carbon deposits.

All the acea oils are extended drain
How does ACEA define extended? Do they put a number or just “follow manufacturer” lingo?

I would use top tier fuel but it’s not sold close to where I live.
I don’t have the patience to shop at Costco let alone line up for gas.
Would you call 20k OCI extended? that's the norm. acea is the association of european car manufacturers, so guess what they would say....
Nonsense

Gotcha. I’ve yet to own EU vehicle, so I never considered their specs in details as I drive a Honda. Thanks for the info.
Well, if you have a better explanation, I'd like to learn the cause. You've used only top-tier motor oils, so what else is there?
I really don’t understand the mentality of using VRP as a cleaning regimen only. It’s seems ridiculous to me. Look at the UOAs of VRP. What oil at that price is delivering materially better UOAs?
People are acting like this stuff is MMO or some kind of sketchy cleaner that you need to abandon to go back to “real oil”. Well guess what, your “real oil” is the reason you needed VRP to begin with.
