With my now defunct 1993 Vintage Camry V6XLE I alway changed the oil every 3K and rarely burned much right up to its accident caused demise.

I'm curious...does anyone know what Toyota recommends for the 4 cyl Camry? Unlike some here, I'm no engineer, but it seems to me that by design, the Hybrid ICE will have had less wear/need for lubrication per odometer mile.

If you assume that the bulk of the MPG delta between the two vehicles is attributable to the E mode or combined mode, then maybe the approximate toll on the Hybrid's oil would be proportion to the MPG Delta between the two vehicles? Perhaps the TCH ICE is effectively averaging lower RPM's due to combo power? In any event, shouldn't that all add up to less frequent need for oil changes? Maybe the combined delta in MPG should be added to the recommended mileage between changes?
