Car oil drain plug gasket kit, 540 pieces

How to use it

If you change oil and want a range of metric drain-plug washers on hand, this kit offers more flexibility than buying one size at a time. It contains 540 aluminium washers across 18 sizes, with several thickness options, in a divided storage case. The listing names sizes from M6 to M24, which gives you a starting point when matching a washer to a drain plug.

The idea is straightforward: find the size you need, place the washer between the drain plug and the pan, then tighten the plug as appropriate for your vehicle. The soft aluminium is meant to compress slightly to help form a seal. For instance, during an oil change, the dividers let you pick out a washer without tipping a mixed assortment onto the garage floor.

Will the broad size range cover every vehicle? Not necessarily. The exact washer needed depends on the drain plug, and the listing doesn’t provide vehicle-specific fitment.

Pros

• The 540-piece assortment includes 18 metric sizes and several thickness options, rather than focusing on just one size.
• Aluminium washers have a smooth finish, with no rough edges or burrs described in the product information. The material is also stated to resist rust and heat.
• Fixed dividers keep sizes in separate compartments, making the case useful for storing the set between jobs.
• The washers are intended for oil drain plugs, with other possible uses listed for boats, generators, shop equipment, hydraulic fittings, fuel lines and electrical connections where a soft metal seal is suitable.

Without having tried it, the practical appeal is the range and the organised case, especially if you maintain different equipment. A limitation is that the number of washers supplied in each size, and the specific thicknesses, aren’t stated. You’ll still need to identify the right fit rather than assume the assortment includes the exact washer for your vehicle.

It suits you if you do occasional oil changes or look after several types of equipment and prefer to keep assorted washers together. It isn’t for you if you need confirmed fitment for a particular vehicle, or a clearly specified quantity in one exact size.

Spec sheet

• Type: Metric flat crush washers for oil drain plugs
• Quantity: 540 pieces
• Size range: 18 sizes, named sizes include M6, M8, M10, M12, M14, M16, M18, M20, M22 and M24
• Material: Aluminium

• Thickness: Several options, individual measurements aren’t provided

The set is aimed at routine maintenance, but its broader suggested uses don’t establish compatibility with every fitting or application. Match the washer to the connection and its requirements before using one, particularly beyond a standard oil-drain job.

What I’d consider

Choose this kit if having a spread of metric sizes ready for oil changes and general equipment maintenance matters more than knowing the exact contents of each compartment in advance. The separate sections should make the assortment easier to manage than loose washers in a bag, while the aluminium construction suits the listed sealing purpose.

If you’re servicing one specific vehicle, identifying its required washer size first is the more reliable buying approach, a large assortment doesn’t replace confirmed fitment. For a home garage that handles varied jobs, the range and divided case may be useful. For a precise repair where dimensions and per-size quantities must be known, the missing detail is a meaningful drawback.
