I had a 3rd gen RX7 Twin Turbo and used Protek-R Synthetic Fuel Lubricant with every tank of gas. I was wondering if anyone has used this in the past, and if it was also recommended for the RX8. I've sent an e-mail to Pettit Racing to get their opinion. I bought my RX7 from them and was very happy.

Here's an explanation of what it is and why it should be used taken from Pettit Racing's website (www.pettitracing.com):



Why do we recommend the use of Protek-R in every tank of fuel? The following is a reprint of the label on the 4 oz bottle of Protek-R:

Protek-R
Synthetic Fuel Lubricant

Protek-R is specially designed for use in Rotary Engines. Protek-R is an advanced high performance synthetic lubricity system which contains precision engineered lubricating molecules that help protect Rotary Engines from the damaging effects of molecular shearing and metal to metal contact. Regular use of Protek-R's superior formula has the following advantages:

- Reduced wear on rotor housings and side housings
- Clean Burn Technology reduces carbon and residue build-up
- Ashless, No smoke formula provides cleaner exhaust than 2-stroke oil
- Anti-Oxidation protection against fuel system rust and corrosion
- Low flash point helps stop plug fouling

DIRECTIONS:
Add Protek-R to tank before adding fuel using the following formula:
STREET: Minimum of one 4-oz bottle per full 12 gallon tank
RACE: Mix at Ratio 100:1

NET 4 FL. OZ.

Rotary Engine Tech Tip

The rotary's oil injection system operates like this: Oil is fed via the engine oiling system (crankcase) to a variable ratio metering pump. From there, it is routed to the engine where it trickles in, partially mixing with the onrushing air-fuel mixture. Fuel-to-oil ratios of 400:1 and higher are common. With over 20 years of rotary experience, we have seen the harsh effects of insufficient lubrication on the delicate internal components of rotary engines. To add to this condition, fuel is of the unleaded variety and designed to CLEAN. High combustion temperatures produced by rotary engines break down the oil film, then today's super fuels finish the job, leaving internal components, i.e. apex seals, side seals, corner seals, etc, void of lubrication. As a result, friction and wear increase, performance and efficiency decrease. Because of this, Protek-R was developed. By adding only 4 ounces to the average fill-up of 15 gallons of fuel, the fuel-to-oil ratio is improved by 100%, bringing the ratio to 200:1 or better. Protek-R can extend rotary engine life by 30% or more, depending on your driving habits and consistency of use.
