I changed my 07 tacoma every 10k w/ mobile1 when the manual required 5k intervals.
When the pickup was wrecked at 211k, I had just done an oil change, and when I checked the level prior to changing it it was right where it should be in the dipstick. Don’t use any oil that was detectable, just as expected
I also changed the tacoma (and now Tundra) at 1000-1500 for the first oil change.
I’m not convinced you will get any more life with 5k changes. Not that 211k is a lot, I think Seafire has a 22r with way over 500k on longer than 10k changes.
