I have a 2008 Toyota Prius with 194,000 miles. It has had BG MOA® in the engine since its very first oil change about 13 years ago. Unlike some Prius owners have reported, my engine does not burn a drop of oil, the engine has remained clean, and it still gets an average of 50 mpg. I also use BG 44K® in the fuel every 15K miles.
