I have a Fumoto on my '13 RAV and it works flawlessly. Because of the location of the drain plug, if a rock gets hi enough to tear off your Fumoto valve the a LOT of other bad stuff is about to happen.
Can accidents happen? Sure! Shoot, my neighbor had a flying rock tear a hole in his oil filter. I don't think anyone would say that we should forego oil filters! Again, this argument is based purely on the placement of the GEN 4 RAV's drain plug. Personally, I like having this because I think it avoids a lot of issues. I change my own oil 95% of the time, but there have been a couple times I have been too busy so I take it too a shop. I've had two drain plugs stripped out by those guys, with one being bad enough that I had to replace the oil pan. You know what is quicker than an oil plug then? I a Fumoto valve, ha!
I like:
Not worrying about cross threading.
Not get scalding hot oil all over my nitrile glove and down my arm.
Not worrying about crush washers.
No splashing into the pan. Just attach a 3/8" plastic tube and drop it in the pan.
Ease of taking oil samples for analysis. I let the oil start to drain, shut it off, put the hose in the jar, turn it back on. So easy and clean.
I personally think they are worth it. That being said, I put these on my cars on a case by case basis depending on angle and clearance. But for the GEN 4 RAVs these are great!
