This product suffers from the same thing every other oil change product does - leaks.I purchased this from AutoZone and was skeptical. The rep told me ahead of time that it will eventually leak, just not as bad as the others. The problems are:* The top lid can be easily overtightened causing the top large lid to leak.* The small side cap can be easily cracked just by tightening rendering the pan useless.It took 3 oil changes for me and this is in the trash. Back to the cheapo metal pans.Just to add.. the AutoZone rep was brutally honest and I appreciate that, great store, just a bad product with no good inexpensive ones on the market.
