Q HORSEPOWER SYNTHETIC $18 for 5Qt Jug - Toyota Yaris Forums

QS products are good for the money. Since I've been running synthetics I've been using Amsoil, as they beat Royal Purple, Mobil1, QS, Pennzoil and several other synthetic oil brands. I've noticed smoother idle in my SPI engines and better fuel economy in all my vehicles, even those that are electronically controlled. Mobil1 would be my second choice for oil. Synthetic all the way - there is no substitute!
