I still use, and insist on, regular oil but change once a year. The engines have a 6 quart sump and get 5W30 conventional. Both are right around 25K miles and are likely cleaner inside than a brand new engine. Synth ain't right for everyone.
I am amazed that you have such low mileages on your RAV6s, I had an '06 and just plain loved to drive the thing!! I have to admit that I liked it more all around that my current FXT, although the Subaru does have a much better AWD system.
I just tend to drive a lot in general (~20k/year), but I think I would have found excuses to take the RAV6 out no matter what...but, yours will probably last a long time with lighter usage. 8 years/160k and my Toyota was feeling kind of tired, so I moved on.
