According to Repair Pal, an estimation service on car repairs the average cost to have your oil pan gasket professionally changed is $474 and $580! The cost for the mechanic’s labor alone is $130 and $145 I happen to think that’s outrageous.
Using synthetic oil member reviews the pricing for an oil change was an oil change typically costs $20 to $55. Using synthetic oil bumps the price to $45 to $70 on average. In my area of the country (United States, all prices are U.S. dollars) it’s $19.95 at Uncle Ed’s Oil Shoppe. Using synthetic oil generally bumps it up to $20.00 or so.
Now I happen to think mechanics have more difficult jobs to deal with than an oil pan gasket. Besides, that’s a lot of money for two or three hours of work that you or I could do with the right tools (and that’s really all it takes, a little knowledge, and the right tools).
