Why choose - On some models the oil filter connection sits behind the engine, making conventional funnels unusable. The universal Engine Oil Funnel Tool solves this with a rotating extension rod and an adjustable thread quick clamp that fits a range of oil connections. It can be easily inserted in tight or obstructed engine bays. Comprehensive design - Large diameter, extended reach, and high transparency. The transparent wall is thickened and hardened to resist damage. The rotating extension tube lets you work around obstructions or in small spaces. The mounting clamp thread uses a sharp wire diameter to prevent slipping. Wide range of applications - Compatible with many vehicles by using threaded quick clamps to match different oil fill holes. Unlike conventional funnels, the Engine Oil Funnel Tool remains usable on some special vehicles where the oil control is behind the engine. Use scenarios - Reaching oil fill points behind the engine on compact cars without removing components. - Filling oil in engines with tight or blocked bays where standard funnels cannot reach. - Servicing trucks or motorcycles with rear engine oil paths that require a flexible, adjustable funnel.
