This product looks interesting; however I am already oversized as a result of grown men not having the intelligence to replace an oil plug. My biggest fear has always been an oil change, something a 10 year old could do; but that is what you get when you go to some of the un-mentionable places. Having just experienced a catstrophe from a dealer who changed my oil in AL, I was faced with the possible replacement of an oil pan as I did not know how long the oversize plug (which I had installed later) would hold up. I just found a 'PIGGY BACK PLUG" which I hope will do the trick. In essence it is a plug within a plug. You screw in the larger bolt with a 3/4 wrench and then you screw in the smaller one which is a 5/8. If you are careful, you should have no problem removing the 5/8 plug and the threads in the oil pan should remain unscathed. I will post my success or dislike for this plug after seeing how it holds up. It can be bought from Advance Auto for less than $5.00. It is made my oil-tite. I also bought an expanding rubber plug as an emergency, (just in case) From here on out, I will do all of my oil changes, gee, I hope I am smart enough to do it, (since it appears to be rocket science up to this point) If anyone knows how to attach photos (which I have inquired in the past) let me know and I will try and post a photo. Best of luck and take my advice, change you oil yourself and you know it will be done right.
