You're saying that even with synthetic oil, Yaris changes are still required every 5,000 miles? I'm not doing that, my last change was with over 7,000 miles on the oil, and I had plenty of additive left. I definitely wouldn't be trying to go 7,000 miles on dino oil without a change.

Your filter wasn't designed to hold that much junk before it's filled. I'm not sure how it'd be with extended run filters.

I did a 10k KM run with my RoyalPurple oil and either toyota filter or fram extended filter i forgot which. The car really felt heavy and didn't want to move by the time i hit 10k (that's about 6200mi)

Anyways.. I have company cars (mazda 2 and mazda 3) that hit 15k km.. 9k miles before oil changes and still doesn't show any apparent problems. no oil consumption after 4years and 100000k km
