But seriously, what experiences have you had with partial mineral/synthetic, and/or full synthetic oils.

For the first time I just serviced my daughters 2011 Camry, with 343000 ks on the clock. I went with a full synthetic oil, so what should I expect from this sort of product?

Has anyone used a mixed oil on their older Patrols?

Did you see an increase or decrease in oil consumption or seepage around the engine?
