Is a brass washer more suitable than steel for use as an oil pan drain plug washer?

Brass is a softer metal and is more suitable because it will ';mold'; and fit the space between the drain bolt and the oil pan better than a steel washer. If you must use something other than brass, use stainless steel as it will not rust as rapidly as plain steel, a tertiary choice would be galvanized steel. In any event if you need to use something other than brass, it should be replace asap with brass.

Actually I would prefer copper to brass or steel. The copper is more malleable. This allows it to better conform to irregular surfaces that are prone to leakage.
a fiber washer is what most dealers us as a replacement
Yes, the softer brass will form to the irregular surface better than the steel. Less chance of a leak.





I am sure you know not to over tighten.
Neither is better. Both are suitable provided you put a nylon washer in front of either one. By the way where's the O.E.M. plug, its the best due to the magnet on the end of it to collect metal shards.
