I never remove when changing oil filter. Just unscrew the canister. Maybe a little more messy but I don't see the point of draining the canister before removing it. Anybody else skipping this step?
Same here. The 3/8 square hole in the cap makes it easy to remove and reinstall the canister w/o special tools. I suppose if it ever comes loose I'll change the little valve thingy but until then I just throw away the extra parts.
I think this thread is discussing how to change the filter, not whether to change it.>I replace my oil cartridge filter on our 3.5L 2G-FE every 5 k miles. We have 3 Toyotas with the 3.5. An '07 Sienna, '08 Highlander and the '10 Rav4. My local Toyota dealership sells a case of 10 cartridge oil filters for $40 out the door. Hendrix Toyota of Apex NC
Why wouldnt you change your oil filter cartridge? A proper oil service is the cheapest insurance you can give your car.
BTW, the '07 Sienna just passed 224 k miles. Beautiful condition.
