Review on High Mileage Synthetic Blend Havoline 5W20 - 1 Quart, 1 Pack (223680720) by Mark Erandio

I had been replacing parts in my car for a couple years now and was wondering if the parts I purchased were just poorly manufactured or what. Randomly, someone heard me mentioning the problems I have been fighting with for a couple years and recommended High Mileage motor oil. I no longer have to buy an Idle Air Control Valve as the check engine light disappeared with the introduction of 1 QUART of this to my 2001 Saturn SC2. I was beyond shocked and am completely delighted with this product.
