Protek-R Fuel Lubricant

If we expect our rotary engines to deliver top performance year after year for many years to come, it is clearly evident that extra lubricant must be added to the fuel. Especially with today's fuels blended with ethanol, it's basically alcohol—great for cleaning, but with rotary engines it cleans away the minute oil film injected by the metering pump. This leaves critical surfaces void of lubricant and unprotected.

Pettit's Protek-R Fuel Lubricant was developed as a fuel premix for rotary engines. Protek-R is added to the fuel tank and delivered with the fuel to all critical surfaces in the engine, benefits include reducing friction heat and wear as well as protection from rust and corrosion, regular use is proven to deliver Performance and Longevity beyond Expectation and Industry Standards.

Adding Protek-R to your fuel has many benefits:

  • First it keeps your fuel pump happy—less friction, cooler running, longer life.
  • Next, it helps prevent water absorbed by ethanol from rusting metal parts of the fuel system.
  • Then, injectors get love: less friction, less wear, more consistent fuel delivery and longevity.
  • For the engine, immediate benefits are improved MPG, and typically fuel savings are greater than Protek-R's cost. Long term benefits are added performance and longevity.

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[1] and higher—are cause for alarm. Also, unleaded fuels typically have additives designed to clean piston engines: the high combustion temperatures of the rotary—together with Ethanol blended fuels—cause the minute film to disperse and/or vaporize, leaving all your critical surfaces clean and dry—without protection. This causes increased friction and wear, resulting in decreased performance and longevity. With over 25 years of experience and more than 2000 rotary engines built, we know that excessive wear on apex and compression seals (as well as critical housing surfaces) is caused from inadequate lubrication, as well as the ethanol typically added to today's fuels. What does all this mean? Without extra lubrication added to the fuel, friction and heat will cause accelerated wear and likely result in premature failure of some expensive engine parts—great for Mazda's profits, but not good for you and me.

Protek-R is consistently proven to reduce friction, heat and wear—extending rotary engine life by 30% to 60% or more, depending on frequency of use (as well as your driving habits).

Protek-R blends completely with your fuel, lubricating all critical internal surfaces. This provides reduced friction and wear, adding longevity and keeping the power—just what the rotary needs to last strong!!

In just one 24 hour race, a Pettit Race Engine will get a lifetime of use and punishment—but since we mix Protek-R in the fuel there will be little wear when compared to the average street engines we regularly disassemble. This is especially evident on turbocharged and high RPM rotaries 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 be a factor? We think so!

Here at Pettit Racing, we know how fun and important it is to have a smooth running rotary engine—and to keep it running for many miles and 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.[2] 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—and that's what Protek-R does best.

Recommended Premix Ratio For Rotary Engines

  • For track use and spirited driving, we mix Protek-R at a ratio of 100:1, or approx. 1 gal. fuel with 1 oz. of Protek-R.
  • For highway & cruising, our minimum recommendation is 200:1, or approx. 1 gal. fuel with 1/2 oz. of Protek-R.
  • Adding Protek-R at 200:1 improves the fuel-to-oil ratio by more than 100%, or 180:1 and better.

Cut Friction. Gain Power. Use Protek-R.

Protek-R for Piston Engines

Within 15-20 minutes of adding Protek to the gasoline of piston engine vehicles, there is typically a 3-5 MPG gain. After the first Protek use with piston power, nearly everyone agreed "It's the best MPG ever displayed, and my vehicle feels smoother an seems to run better!"

Many folks disagree about adding lubricant to the fuel. "How could that help?", they ask. Think about this: it's not unusual for diesel engines to run a million miles, but gas piston engines never even do half that. Both use nearly the same parts and materials, but diesels have three times more compression, more stress and loads, etc. So why is it they last the longest? Diesel fuel is basically oil!! There is no doubt that using fuel lube in gas piston engines will more than double their longevity!

Recommended Premix Ratio For Piston Engines

  • On piston engine vehicles, we use a half an ounce per gallon, which equals a ratio of 200:1. Nearly everyone that's tried it has gained 3-5 MPG within 15-20 min of use—on both old and new cars.

For example: A piston engine in an SUV used to get 17 MPG, but after adding Protek, it gets 20 MPG— a 3 MPG gain. Using at a ratio of 200:1—or 1/2 oz. per gallon of fuel—means 1 gal. (128 oz.) of Protek treats 256 gallons of fuel. Even just 3 extra MPG = 256 x 3 = 768 extra miles, and 768 extra miles / 20 MPG = 38.4 extra gallons. At $2.50/gal, a fuel savings of $96 or more results from every gallon of Protek added!

Thus, the immediate benefits are fuel savings—which are typically double Protek's cost, while the long term benefits are an increase in engine life expectancy by 30 to 50%!


Q: How do I measure Protek?

A: Many customers have commented that for measuring Protek, they use a 1-quart motor oil bottle that has a translucent stripe down the side, with graduations in ounces and liters—you can clearly see the level and it's easy to use.

Q: What if I put in too much?

A: You really never have to worry about putting in too much lubricant. Most air-cooled 2-stroke engines use a 50:1 ratio—2 ounces per gallon.

Protek-R is available in the following sizes:

1. Fuel to oil ratios are calculated by oil consumption/mile.

2. Low compression can also result from catastrophic engine failures and overheating.
