EP has 3 grades available at most oil distributors, 0, 00, & 000. You will find these used in the mining and heavy equipment industry. Snapper dealers use EP-0 in their transmissions. The sell it in quarts. We use EP0 &000 in many AG machines because gear boxes are often concealed and if a seal failure happens the farmer has a greater margin of time to discover the seal failure before the gearbox has totally failed. Do not use EP grease if heat dissipation is needed. A gear oil will be better to use in this situation.
