Yamaha

Yamaha Motor Co., Ltd. is one of the world's largest manufacturers of motorcycles, marine outboard engines, ATVs, and power equipment. Founded in 1955 as a spinoff from Yamaha Corporation, the company is headquartered in Iwata, Shizuoka, Japan. Yamaha's US chemical products — marketed under the Yamalube brand — are manufactured by Spectrum Lubricants Corporation in Selmer, Tennessee.

Yamalube additives are OEM-spec formulations designed specifically for Yamaha engines, though they work with any compatible gasoline powerplant. The fuel stabilizer and fuel treatment products are particularly popular with marine engine owners and small-engine users who store equipment seasonally.
