QUESTION:  Can I use synthetic oils in my RX7?

ANSWER:  Yes and no. Mazda officially does not recommend the use of synthetic oils in rotary engines, however, it has long been proven that the better synthetics (Redline, Amsoil, Neo, Royal Purple, Mobil1) are perfectly fine to use in a rotary engine, and will generally result in a 1 to 2% horsepower gain. However use of poor quality synthetics (like Valvoline, Castrol Syntec, Havoline, Etc) will result in build up due to high ash content left from these oils when they are burned. That is why Mazda did not recommend synthetics, because they couldn't pick favorites.
 

QUESTION: My RX7 seems to use a lot of oil. How often do I need to check it?

ANSWER:  Every time you get gas, you should check your oil level. The Rotary motor by design is supposed to inject oil into the engine based on throttle position. If you keep your foot on the gas a lot, you will use more oil. It
is normal to use about 1 quart of oil every 1000 to 3000 miles.
