New to this site so heres my intro
Glad to be a member here, my name is John. I just became the owner of a 1987 RX7. Its a 5spd and N/A currently... It came equiped with headers, K+N filter, after market guages, and a crazy horn that does 5 different tones.... I have had some cool cars but never a rotary kind. I am interested in alot of information. I bought yesterday, a Haynes manual. I also am a Fan of Royay Purple Synthetic oil, but I have been told by 2 people DO NOT USE SYNTHETIC in the rotary??? Why? Also both people recomended Castrol 10W-30 regular oil. I have also been told not to use higher octane gas than 86..??? If anyone here can get me going down the correct path and explain to me anything about this stuff, I'd greatly appreciate it. I will become a regular user of this site because I have long term goals with this RX7.

Welcome john to the rotary world lol. i'm a new member as well but not new to rotaries so let me see if i can answer some of your questions. first when it come's to synthetic oil,the only brands that i know of that are compatible with rotaries. are royal purple so your safe with that brand, and this some what expensive brand from japan that you can purchase from Mazdatrix.com it's called Idemitsu. the reason your limited to those brands is because those particular brands contain additives and other base oils that burns more easily in a rotary Combustion, as in other brands will not burn well or not burn at all and will give you new problems. as for non-synthetic oils,pretty much any brand will do,but don't be cheap lol.
When it comes to octane on N/A rotaries by my research. the lower the better but not to low,the reason being is because on N/A rotaries the compression is not high enough to warrant the high octane levels. in fact if you where to put fuel with a higher than 86 octane rating your more likely to lose horse power rather than gain any. the only time you will need high octane on rotaries, is if your using forced induction Like turbos or super chargers and if your using nitrous.
