that's because the apex seals are made of some soft metal. if you don't do the recommended oil change interval, they will wear out very fast.

that's what makes the routine maintenance so expensive, imagine full-synthetic oil change every 3000km.
You are totally off here. For RX-8 Renesis engine, it is recommended that you use mineral based engine oil, not fully synthetic. I am currently using Quakerstate 5W-30 (found it at True Value). As for the interval, I am planning to change it every 5,000 kms. As for any mechanics in the Philippines, I am still looking for one.
