Name: South Valley Synthetics. Descripton:Amsoil products for all gas & diesel powered engines along with most common oil filters available. Enjoy cooling running autos and motorcycles. Why Amsoil? Documented longer engine and transmission life. Extended drain intervals; up to five times OEM while protecting engines better than any other available engine oil. Typical gas/diesel mileage improvements are 4 - 6%. My minivan got 8% while car improved 1%. Near wholesale prices include taxes. Save on both taxes and shipping by purchasing locally. Transmissions really do last longer, shift more smoothly, and very often chronic problems stop with the use of Amsoil transmission fluids.
