well i came home today opened a letter from a don jagoda associates, inc and it said congradulations we are excited blah blah blah blah. youve won a years supply of syntec. latters rite there



so my question is should i use syntec on my 91 turbo to or dont bother cus im alittle scared wen it comes to synthetics

 

Can I use synthetic oils in my Rotary engined car?
Yes and no. Mazda officially does not recommend the use of synthetic oils in rotary engines, however, long term and racing use has shown 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. It is believed that is why Mazda did not recommend synthetics, because the couldn't pick favorites.

Other notes:
The Mazda Factory racing departments recommend and use ‘synthetic’ oils including the winning 1991 Leman’s 20-G 4 rotor Mazda 787B.

MazdaComp USA printed manual (now Mazdaspeed) recommends the use of synthetic oils for racing conditions.

Redline, Amsoil and Royal Purple Synthetic Motor Oils have been used in rotary engines (both race and street) for ten plus years with excellent results.

Most Synthetic Motor Oil is compatible with the bearing material, sealing elastomer's, and combustion seals used in a rotary engine.
