M-40 grade fuel oil has lower viscosity and pour point than M-100, which makes it easier to store, pump and ignite. It suits mid-size heating boiler houses and reserve fuel facilities. Caspian Oil Industrial Company ships M-40 from one tank car across Kazakhstan, Russia and the CIS; for deliveries to Russia, send a request to office@caspian-oil.com.
