Everything you need to get started changing your own oil! Included in the Starter Kit is a 10L Oil Drain Bag, plus FlowVent™ Bag Attachment. The ValvoMax FlowVent Bag and Attachment Kit is a self-contained oil drain system that makes a secure connection from the vehicle to the oil drain bag for a clean oil transfer. This patented closed drain system controls oil flow and bleeds air as the bag fills. The FlowVent Bag can hold motor oil up to 121°C (250°F).
