In the end I think you would get much more interest if you posted in the general section.
I guess it all depends how you change your oil. Personally, I am the biggest klutz, and when I change my oil, I dont have the luxury of a trolly jack, so I only just have enough room underneath to reach in with my hands to undo the sump plug, I always get my hands covered in oil and usually lose the plug into the bucket I catch the oil with.
So for ~$50 to save me all that hassle, meh why not?
I am just worried because I am so low, would it catch on anything, or be whacked by a high speed bump, or get hooked on something, but they say it is only 10mm longer than the standard plug, and they report they have never had any problems, but that is easy to say, they wont lunch thier engine if mine decides to be the first plug to be ripped off......
Anyway I reckon it is a good idea and you would attract more people by posting this outside the stagea section.
Have fun!
