Direct-Fit Oil Funnel 87021

The OEMTOOLS 87021 threads directly into the engine filler neck to eliminate spills during oil changes. Its wide-flow passage allows rapid refilling while a transparent lower chamber lets you monitor the oil level. The funnel is designed for a secure, hands-free fit on a long list of vehicles from AM General, BMW, Buick, Cadillac, Chevrolet, Dodge, GMC, Holden, Hummer, Isuzu, Oldsmobile, Pontiac, Saab and Saturn.

Replaces Generic Pour-In Funnels

Unlike universal funnels that sit loosely in the filler hole, this model screws in place to prevent tipping and splashing. The upgrade is worth it whenever you service any of the compatible makes listed above and want a cleaner, faster fill without holding the funnel. It is not for engines with different thread pitches or for transmissions, coolant systems or other fluid reservoirs that lack the matching filler-neck threading.

Threaded Filler-Neck Interface

The funnel only works on filler necks that accept its specific thread pattern, so it cannot be used on vehicles outside the listed makes. The transparent chamber provides a visual check but has no graduated markings for precise volume measurement. Orders of 75 or more qualify for free shipping direct from the manufacturer.
