This had been discussed here before. The ex-moderator Chris_Top_Her did an experiment on his 2015 CX-5 by actually removing the oil pan and seeing how much the Fumoto valve sticking out inside the oil pan, and how much the oil will be stayed inside the oil pan with Fumoto valve. When he removed the oil pan, the substantial amount of oil left in the oil pan leaking out and caught him by surprise even thought he had drained all the oil with Fumoto valve. He posted pictures showing how much the oil will be stayed in the oil pan with Fumoto valve sticking out inside the oil pan. There’s another member actually measured the length of the thread of the drain hole, and cut the Fumoto valve to match, so that it won’t be sticking out inside the oil pan.
And when did I say ”using this product is detrimental to engine life?”
The fact of matter is the company claims “It is unlikely that your Fumoto valve would be sticking out inside the oil pan. Your Fumoto valve would allow you to drain just as much oil as your original drain plug.”, which simply is not true!
No, it’s not just my personal opinion, it’s the fact.
See post #2:So is the conclusion that the Mazda oil filter tool should only be used with the Japanese made filter and not the Thai version?
Whats the basis of nipping it? I plead don't nip your Fumoto!!! Fumoto lives matter!!!I have the Fumoto to install and will shorten it 1.5threads. But I also forgot I had from a previous car, an oil sucker. That oil extractor works great! I stick the tube in the dipstick tube till she hits bottom and go away for 20 mins. Then do the filter and drain with no much left. Only problem I have now is the hex tool to remove the drain plug is wallowing out. And I'm glad I have the Fumoto. :
I just did the 1st oil change on my daughter's 2021 CX5 GT today and came to the conclusion that I need a filter wrench/cap for the the next time. Searched and found your post, I will order the filter cap you posted. Thank you for your contribution.Yes, Thai made OEM Denso oil filters are a bit smaller in diameter than Japanese made OEM Tokyo Roki oil filters. The stock oil filter on 2.5T is Japanese made Tokyo Roki PY8W-14-302, but Mazda North American Operations had stopped supplying PY8W-14-302 a couple of years ago and it’s superseded by Thai made Denso 1WPY-14-302 which is smaller. Usually it isn’t an issue unless you use cap wrench on the oil filter. I ordered a "Genuine" Mazda Oil Filter Wrench A255 for $10.20 from Med Center Mazda along with oil change kits years ago but it ended up exactly the same as https://www.amazon.com/dp/ (commissions earned)https://www.amazon.com/dp/ (commissions earned) The sizes of CTA A255 cap wrench are 65 & 67 mm with 14 flutes. It fits Mazda OEM Japanese oil filter perfectly on 67 mm and OEM Thai oil filter on 65 mm size.
Here is the size comparison between Japanese and Thai oil filters for my 2.5L. The sizes of OEM oil filters used on the 2.5T are the same as on the 2.5L.
