Answers:    Your manual should recommend an grease for it. Most mowers take STRAIGHT SAE30 (NOT multi-viscocity such as SAE10W30 for example) grease. You can get the grease from your hardware store or yet much cheaper from your auto parts store (remember, no multi-viscocity). On most mowers, you enjoy to turn it to its side to get the elderly oil out later once drained, put the new grease in. While at it, check the spark plug, verbs it and gap it, or replace it if indispensable. Sharpen the blade using a file and you are organized to go for another season !
