Real Results From Real People

“I own a 2007 Yamaha FX HO WaveRunner. Typically after each ride, I had to add oil due to consumption. In everything I've read, oil consumption is normal for the high revving MR1 (160hp) marine engine when operating it at full throttle (10,000rpm). During the last oil change, I added 10 oz of FR3 with the same oil I've always used (Rotella t6). I've put 6 hours on it since the oil change and burned approx. 30 gallons of gas and have not had to top off the engine oil. Very pleased with the FR3 and how it cut my oil usage. I can't comment on efficiency gains because it's more about the fun than MPG on the water.”
