Protek-R

If we expect good longevity and top performance from our rotary engines , it is clearly evident that extra lubricant must be added to the fuel.

This is why; the oil metering system is responsible for lubricating the delicate apex seals, compression seals and housing surfaces that are common to every rotary engine. Oil is fed from the engine oiling system (oil-pan) to a variable ratio-metering pump, then it’s injected into the engine where it partially blends with the onrushing air-fuel charge, this incomplete blending and fuel-to-oil ratios of 400:1* and higher, are cause for alarm, but now add in unleaded fuels that are designed to clean piston engines, these fuels and the rotary’s high combustion temperature quickly clean away this small amount of oil leaving little or no lubrication. This creates more friction and wear, resulting in decreased performance and longevity. With over 25 years experience and more than 1,000 rotary engines built, we know excessive wear on apex and compression seals as well as critical housing surfaces happens from inadequate lubrication and using today’s fuels. What’s all this mean? Without proper lubrication, friction, heat and today’s fuels will most likely precipitate premature failure of some very expensive engine parts, this is great for Mazda but not so good for you.

By reducing friction and wear Protek-R can extend rotary engine life by 30% or more, depending on your driving habits and consistency of use.

Protek-R completely blends with your fuel lubricating all those critical surfaces, as it provides reduced friction and wear, adding longevity while keeping the power range stable. Just what the rotary needs to last strong!

In just one 24 hour race a Pettit Race Engine will get a lifetime of abuse and punishment, but since we mix Protek-R in the fuel our engine has little wear when compared to the average street engines we regularly disassemble. This is especially evident on turbocharged and high RPM rotary engines like the Renesis.

Pettit Built engines are the only turbocharged rotary engines in racing history to finish the grueling Rolex 24 at Daytona, could Protek-R be a factor?

We think so!

Here at Pettit Racing we know how fun and important it is to have a good running rotary engine and keep it running for many miles and even years, that is why Protek-R was developed in the first place, to help keep your engine fresh.

For RX8 owners, some Renesis engines have weak or low compression**, Mazda says “heat generated friction” is the cause, but since factory recalibration for the RX-8 ECU increases injected oil for the high revving Renesis; could they just need some Protek-R to help cut friction and reduce wear? We think so too and that’s why we recommend using Protek-R.

By adding just 4 oz of Protek-R fuel lubricant with an average fill up of 10-12 gallons of fuel, the fuel-to-oil ratio is improved by 100%, or 200:1 and better. Cut Friction Gain Power, use Protek-R.

*Fuel to oil ratios are calculated by oil consumption / mile.
**Low compression can also result from catastrophic engine failures and overheating.


For racing purposes Protek-R fuel lube is mixed with fuel at the ratio 100:1 or aprox. 1oz./gal of fuel.

Protek-R benefits include:

  • Extended engine life
  • Reduced internal friction and wear
  • Less drag means more power
  • Added protection against rust and corrosion
  • Blends completely with fuel and will not separate
  • Easier starting
  • Carbon free
  • 100% Synthetic

Protek has proven itself for over 20 years in every type of racing. In 1998 Pettit Racing won both the Team and Driver Championships for the U.S. Road Racing GT2 Series. Pettit Racing has also won five SCCA Road Racing Championships, over fifty national races and still sets numerous track records in rotary powered cars.

These Rotor Housings are out of 13b Rotary Engines

The housing on the left has seen regular use of Protek-R fuel lubricant; it has approximately 80k miles with and would be reusable if it hadn’t been cut for this comparison.

The housing on the right never received Protek-R fuel lubricant, it has only 60k miles. Several areas of wear prevent this housing from being reused:

  1. The area just above the tralling spark plug hole is scored and has uneven wear.
  2. Chatter marks on the minor axis approaching the leading spark plug hole.
  3. Compression leakage from just before the leading spark plug hole extending down several inches as indicated by discoloration in that area.
  4. Chipped chrome from the apex corner piece near the exhaust port (not shown in picture)
