This is an important anecdote. It helps explain some of increased oil burning we've seen with some people who were burning oil. Perhaps the ring deposits were providing some seal, and the Valvoline Restore and Protect removed it, and the rings were still stuck but no longer sealing as well. Additional OCIs needed to free up the rings, with resolution of oil burning.

Glad I got one in before the impending shortage that is going to summarily consume us all.

Amazingly no, and I hear that's very common in the theta II engines
Kirkland 0W20 drain and fill with a MityVac 2nd drain and fill and am at 4,700 miles.
What is the oil change history? Have you always run Euro oil? That's a good result in those engines!

Onto my second run of Valvoline Restore and Protect 5w-30. Just as before swapping to Valvoline Restore and Protect, the motor doesn't seem to consume any oil between changes, it's right at the full mark every time I check.

Out: Supertech 15w40 / Baldwin filters.
In: Same.
We noticed the service manual states 22 qts but shows full on the dipstick with just 18 qts.
Update: , after letting the truck sit for awhile after idling for about 5 mins , turns out the service manual is correct. It required an additional gallon to actually show true full on the dipstick.

I really like mine too. It's so easy to change the oil and I can go a year on a filter. I will be changing the filter fairly soon since it's a newer vehicle with less than 5,000 miles. I need to do this for the warranty to remain good.

Dad’s been driving this since I got my RAV4. It has some oil leaks but to repair them is pretty costly and not something I can do in my driveway because it’s the timing cover that’s leaking and rear main seal so basically they won’t get done and when it dies it dies lol. I kind of miss it but I realize how much I enjoy my RAV4 whenever I think about it lol. His Buick is parked at my work and I’ve been having to keep it running too.

It's my mom's car, I've changed the oil since she got it new in 2011. I initially used Quaker State ultimate durability 5w30 but switched to the euro probably 5 or so years ago once the recall was issued on the engine and they installed the knock sensor in it.
