Situation: We have a 2009 Venza, 90k miles. Healthy motor, doesn't seem to use oil. Gets Toyota filters. A little piston slap when cold for the first few miles, then subsides. Has never had VVTi clatter on startup. Tolerable/light front cover seepage for the last 30k. I typically run PP-HM 5w-30 or M1-HM 5w-30. Has always had 5k changes, but has spent much of its life as a short tripper. The car is well maintained and beautiful. My parents bought it new, so we are familiar with the history.
Virginia, garaged, so cold starts below 40 F are rare. Someday it might be an outside car, in which case it'll see less perhaps a dozen starts in the teens a year.
Problem statement: Last oil change (5k, 9 months) was dirtier than I would like to see. My wife drives it. Our habits have changed. Short trips, short trips, short trips. Poor thing sees 25 legs of travel a week and probably only cracks a thermostat on 5 of them in the cooler months.
Plan: My plan is to switch to an A3/B4, available from Walmart and switch to a 6-month OCI. Probably Castrol Edge 5w-30 Euro, as the viscosity is a slight step up (12.1 vs the 10 or so it seems happy with.) Other LL-01 type euro oils available at WM are Edge 5w-40, M1 0w-40, and M1 5w-40. PP Euro L 5w-30 is also available, but is C3, LL-04. Let's assume all of the oils I've mentioned are the same price.
Question: Does the habitual short use warrant the change to a euro spec oil? Alternative, stick with the PP-HM and do the six-month changes.
I know the motor isn't picky, but I'm assuming there isn't anything bad about going to high SAPS, high HTHS, even if the benifits are slim-none.
I know I'm overthinking this. (Isn't that what this site is about?) Thank you for indulging me.
