Oil type and quantity
The recommended oil for MTD engines is an SAE 10W-30 oil with an SM API rating or better. The oil capacity for
all of the P90 series engines is 57 fl.oz (1.7 liters).
•
If the oil is noticeably thin, or smells of gasoline, carburetor repair may be needed before the engine can
be run safely.
•
Check the oil level frequently and change the oil more frequently in severe operating conditions such as
exceptionally deep snow falls.
•
Synthetic oil is a suitable alternative, but it does not extend service intervals.
NOTE: MTD recommends the use of petroleum oil during the break in period to ensure the piston rings cor-
rectly break in.
Synthetic vs. Petroleum based oil: To simply look at synthetic oil and to compare it with Petroleum based oil
there is very little difference. However, when you look at the two through a microscope it is easy to see the difference.
Synthetic is made up of smaller molecules. This allows the oil to get into areas that petroleum based oil cannot.
