WINCO recommends our 5W-40 fully synthetic heavy duty
engine oil to give you maximum cold weather protection
while maintaining excellent performance in warmer
weather. We have partnered with a national lubrication oil
manufacturer to give you access to Winco private branded
premium oil available at comparable prices to conventional
oils. See your dealer for additional information.
WINCO has plumbed an oil drain valve to the outside of the
unit. Attach a customer supplied 5/8” hose to conveniently
run the oil to a drip pan or suitable container for catching
the oil.
1. Drain the oil by removing the plumbed oil drain valve.
2. Once the sump has fully drained, close the valve.
3. Top-off through the filler cap (1) using lubricant oil
with the suitable oil table in the LUBRICATION section
of this manual.
4. Use the dip stick to ensure the level of oil does not
exceed the “MAX” limit.
5. Insert the dipstick and close the lubricant filler cap.
6. Dispose of oil in accordance to local codes. DO NOT
dispose or allow oil to seep into the ground or sewer
systems, doing so will cause environmental damage.
