It is ideal for tight or obstructed spaces. 2. Comprehensive Design: The funnel boasts a large diameter, extendable length, and transparency. Its thickened transparent walls enhance durability and prevent damage. The rotating extension tube ensures effortless use in cramped or obstructed oilfilling areas. The mounting clamp's sharpthread design prevents slippage. 3. Wide Compatibility: Suitable for various vehicles, the threaded quick clamp enables easy insertion into different oil filler holes. Unlike traditional funnels, this engine oil funnel tool works seamlessly even in special vehicles where the oil port is positioned behind the engine.
