Thanks Cdn17Sport6MT. My original intent was to continue to use the OEM plug as well, but I'm reading anecdotes of people stripping the hex key hole, requiring the drain plug to be replaced at $12 a pop every few oil changes. No doubt they're not using a torque wrench and/or are tightening the plug too much...but it got me thinking...
A Fumoto valve is only $25 to $30, and should last the life of the car. A few replacements of the OEM drain plug and the valve would have paid for itself. Plus it gives you the added convenience of easier oil changes and less mess. I think I'm just going to go ahead and get the F106S valve. It's got a shorter nipple than the F106N, and while there's no clearance issue on our cars, I don't want the valve body to protrude any further than it needs to.
Also taking this opportunity to re-iterate my questions from yesterday, so they don't get lost in this thread. I'd appreciate any guidance on the oil filter if anyone is knowledgeable on that:
1. Which Mazda OEM oil filter to use? It looks like there are at least 3 different filter part numbers for the Mazda 6:
PE01-14-302 - This was the original filter, made by Tokyo Roki in Japan. Seems to be a great quality filter, but it's unclear to me whether it's available anymore.
PE01-14-302A - Does anyone know what the difference is between the 302 and 302A versions? Presumably the A is the newer model, but is it still made in Japan and is one objectively better than the other?
1WPE-14-302 - It's made in Thailand, and people say it feels lighter and not as well constructed as the Tokyo Roki PE01 filters, but it seems to be all that dealers sell now. It's unclear who manufactures it. People speculate that it could be Tokyo Roki or Denso, both of whom have plants in Thailand.
I also see references to a Mazda Value filter, though it's not clear whether that's sold anymore, whether the 1WPE-14-302 is that filter's successor, or value even means that it's somehow inferior to the non-value version. What do folks here do? Do you just install the 1WPE-14-302 because it's the latest version and readily available, or you do go out of your way to source a PE01-14-302(A) filter?
2. Which Fumoto valve to use? I wasn't initially thinking about installing a Fumoto valve, but that replacement OEM drain plugs cost about 1/2 the price of a Fumoto and the hex head will inevitably strip out every few oil changes, I think I'm just going to go ahead and install a Fumoto and be done with it. I like the promised convenience and that fact that it eliminates the risk of stripping the drain plug and/or pan with every oil change. Which version of the Fumoto valve do you recommend?
F106N - This seems to be the one most people have opted for (not sure because that was the only option in 2014, or if people just piled on when someone started using it. It's got a longer nipple than the other one I'm considering, which is both good and bad. The good is that it makes it easier to put a plastic hose over it to drain the oil neatly. The bad is that it makes the whole valve stick out further. Is there any clearance issue with using the F106N?
F106S - This looks like the same valve, but with a short nipple. It's harder to secure tubing over the S, but the advantage is that the valve body sticks out less
