The buyer of your vehicle will thank you. I wish all people are as meticulous as you do.
You are really a representative of a great BITOG-er.
For me, the reason to use quality oil and quality filter is the ability to own and operate the vehicle up to 300K to 400K.
At that point, if somebody buy the vehicle, I don't think they will ask what was the OCI.
Well, if it does, my answer will be "it has lasted this long, what do you think?"
Just IMHO.
My Sienna is close to 240K miles. It has been on 10K OCI of mostly Mobil1 and on sale high end oil filter since I bought it 117K miles. Very smooth idle, better than when I bought it. I do replace the filter every 10K.
Sorry, I don't answer your question since there are a lot great answer already.
