I am SO glad I just saw this pop up in my "purchased" items category...I am not only a Do it yourselfer but I also perform service work for a group of clients as well and I have to say I had a version of this before and threw it out after many years of service due to the fact it started dripping/leaking and I did not want to waste time trying to find it! with that said I purchased this and "What a mistake" every time I change the oil if it does not hit exactly the right angle or area the oil just ricochets off the surface and splashes all over the garage surface (especially when working with 0w20 type oil - thin)...I think this one will be seeing the can soon as well even after only 30-40 uses!!

Rare Small Leaks

Style: 16 Quart Drain Pan

These work well but i have noticed that they leak in small amounts from time to time. Can be a little annoying when transporting used oil or coolant to be recycled.
