Schaeffer Manufacturing Co. DuQuoin is proud to announce our new line of full synthetic motor oils with formal dexos1Gen3 approval from General Motors. 

Schaeffer Mfg. Co. Duquoin stays on the cutting edge of North American motor oil technology with our new line of GM approved dexos1Gen3 full synthetic motor oils. 

After many years of selling API licensed motor oil, Schaeffer Mfg. Co. Duquoin has decided to offer a line of motor oils formally approved for dexos1Gen3 applications. The addition of this product line will allow Venom customers to cover a large portion of the North American motor oil market with one product. Superior performance and short lead times will allow Schaeffer Mfg. Co. Duquoin’s partners to stay competitive in the marketplace.
