Has anyone herard of this oil? Its made by Purol USA out in Ontario, CA. Its a little pricey at 13.99 a quart, and they claim it can help clear up to 12HP! I drive a 2011 Hyundai Sonat 2.0T and paired that with an awesome Hyundai OEM oil filter (the BEST OUT THERE...IMHO) and wow, it smoothed out the engine so much during idle and best of all throught the entire poer band. Ithink the only mistake was NOT getting a before and after DYNO....just to see any changes if any. Based on my FIRST IMPRESSION I already HIGHLY RECOMMEND this OIL. Hopefully price will come down just a little. Otherwise very satisfied customer! Let me know if any of you have tried this!
