A very expensive thing for the dealer since they must certify the emissions system for 100,000 miles. The engine itself loves the stuff. I have around 1200 hours in the plane on Mobile1. Tracy Crook tcrook@rotaryaviation.com www.rotaryaviation.com ---------------------------------------- Thank you (and Rino) for providing the true answer to this. In all the threads I've read on the RX-7 list, you'd think someone would have mentioned this, but if they have, I didn't see it. This makes perfect sense now. Many people change the exhaust, and dump the catalytic converters, so I guess it doesn't matter to them. For now, mine is completely stock, so I'll steer clear of the synthetic until I have the time and money to start modifying the car. Thanks again, Rusty
