Title: Still ticking after 3 years
Review: This is still in my car and I simply buy the refresher pack every year. It's high performance and lasts a life time. Plus I'm not throwing out a filter every year. Probably saving a few bucks as well. I have a 2004 mazda rx8 and have had no problems relating to the oil used on the filter. I still clean my MAF sensor once a year which might help but I'm glad i bought it and recommend it to anyone.
