Ok, our cars have tiny little 3sfe engines. I drive An acura TL and an Acura TSX regularly. I can't bear the horrid acceleration our little light duty trucks give us. When mine reached middle age at the 100,000 mile mark i threw some of that restore oil treatment in to see if it did anything. I expected nothing and was greeted with a smoother, stronger, throatier sounding pull in the low to mid RPM range. My sticky idle control valve problem also disapeared after running the newly powerful rav really hard. (don't know if it has to do with the oil treatment or the 3 hours of drag strip testing to see if the numbers matched when it was new. Acceleration is back yay! ) This stuff is awesome. Even our invincible toyota engines can use a little help. Go buy it, it costs 5 dollars and will give you a boost back to brand new.
