On the 14 Venza, I do an oc every 5K and a filter at 10k (Fram Ultra). I did a particle analysis once at a 15K filter change and there was too particles at 4 and 6 microns.I'd start changing oil at every 5000 miles on the odometer. Easy to keep track of.
On my 4Runner, I did a spill and fill of oil only on the 5Ks and then oil and filter on the 10Ks. The cartridge filter always looked clean after 10K miles. I'll probably do oil and filter on the 5Ks and 10Ks on my RAV4 since the spin-on filter is quick and easy to change.
Pennzoil has a good rebate going on right now for Pennzoil Platinum and Ultra Platinum oil.
Do not do a 15k filter change despite the filter is rated for 20K, Too many small particles.
