Comments about Flat Tank Oil Changer:

This is a strong pump amd did the job. My only issue with the pump is that
It was pulling in air somewhere and did not give evan a some what even flow
Mostly spitting the oil out. I did start the engines to warm up the oil so that is
Not the issue.not sure what caused that. Took a little longer than I thought it
would but did the job as expected for a good price.

      Comments about Flat Tank Oil Changer:

      This thing DOES NOT WORK! I tried pumping out with the engine hot from the dip stick line and from the oil pan line. After twenty minutes it barely pumped out one quart. I tried fiddling with it thinking maybe I did something wrong but it didn't make a difference. I took it back to a different store then I bought it from and the lady told me these things are junk, refunded it, and sold me a manual pump. The manual pump pumped the engine out no problem. DO NOT BUY THIS THING! West marine should be pulling it off the shelf.

        Comments about Flat Tank Oil Changer:

        The pump is very quite and does a good job. It pumped 8 quarts of oil in approximately 45 minutes. Be sure to get the oil hot, running at engine temperature for a few minutes is not sufficient. Not sure about durability, but appears to be well made.
