RAV4 with 29,900 miles. Is a DD and driven very easy. Good mix of trips less than 10 miles and between 11 to 40 miles. 80/20 split local/highway.
Dealer performed first two oil changes. Last one in July 2018.
Paperwork for first change detailed Toyota SN+ 0w-20. Paperwork for second change was vague and ambiguous so assume dealer bulk of unknown origin though 0w-20 was noted. Local mom n pop dealership sold to out-of-state automotive superstore type January 2018...world of difference and red flag.
I changed oil and oil filter May 2019 and sent sample for UOA. Filter was Toyota/Denso and was in decent shape with no noticeable particles to cause concern.
Also installed Fumoto valve, and replaced air filter, cabin filter.
Plan is to pull sample at ~6000 miles and send for UOA. Will include TBN next UOA.
Didn't figure TBN was worth it this time because of unknown oil origins so not much useful info going forward.
Just setting the baseline.
