NOTE: Watch out for the spring in the filter cover behind the filter popping out with the old filter. To help you install the replacement filter correctly, Honda labels which side of the oil filter faces out.
Step 8: Replace the oil filter cover, then hand-tighten the 8mm bolts. To prevent leaks, use your socket and ratchet to evenly tighten each screw.
NOTE: The spring beneath the oil filter may require some pressure to be applied to the lid in order to thread the 8mm bolts.
9. Use the fill port on the left side of the engine, which is located opposite the dipstick port on the right, to add Honda 10W-30 motor oil to the engine.
NOTE: The Honda Rancher 350 only requires slightly more than 2 quarts of oil, so start with that amount.
Step 10. After letting the engine run for a while, check the dipstick to determine the exact oil level. If necessary, top off the oil to the proper level.
How much oil does a Honda Rancher require?
Oil the engine once more. ADVICE: Despite Honda’s claims, we considered the Rancher 420’s 3 quarts of oil capacity to be a tad excessive. Replace the fill cap, add 2.5 quarts, let the engine run for a few minutes, and then check the level. Don’t screw in the fill cap before checking the oil level in the engine.
