Back in the day, it was said not to use synthetics in rotary engines. However, synthetics have come a long way since then and are fine to be used. What weight did you use?

Skip at KDR recommends Castrol (natural oil) for the break-in of rotaries, and he's been at it 32 years. After that though, he said it doesn't make much of a difference whether you use synthetic or not, the only difference is turbos like synthetic better.

awesome...im not breaking in any new parts, so i suppose it was worth it going synthetic...thanks
