I had a leak develop on my van. To keep it short the crappy STP oil filter has a hole in it. I got the thing free after rebate and was some what suprised at how light and flimsy it felt.I installed it any way. I noticed a small oil stain under the vehicle and observed a little indentation on the filter. The oil was dripping through a small crack.Back to Purolator for me. The STP is just too cheap and flimsy.I have a pic if anyone is interested.
