Filter Replacement

Locate Oil Filter: Place your drain pan under the oil filter as well, as some oil will spill.
Remove Filter: Use an oil filter wrench to loosen and remove the old filter.
Prepare New Filter: Apply a thin film of new Chevron Delo 400 15W40 to the rubber gasket of the new filter. Fill the new filter partially with new oil (about 2/3 full) to prevent dry starts.
Install New Filter: Hand-tighten the new filter until the gasket makes contact, then turn it an additional 3/4 to 1 full turn. Do not overtighten with a wrench.

Refilling and Checking

Add New Oil: Using a funnel, slowly add the recommended amount of Chevron Delo 400 15W40 to your engine through the oil fill cap. Refer to your owner’s manual for the exact capacity.
