This months question comes from Victor in Elizabeth, NJ. Victor writes, "I have an RDX that requires the use of synthetic oil, do I have to do this or can I use regular oil in my truck." Victor, the answer is NO. Your vehicle is equipped with a turbo charger that creates, in addition to exceptional power, additional engine heat. Acura recommends the use of synthetic oil because it is more resistant to this heat and provides better engine protection. Make sure you continue to use synthetic oil and follow the Maintenance Minder system on your dash board, this will ensure years of reliable service from the Acura you love. A complimentary oil and filter change certificate has been emailed to you for your cooperation, thank you for participating!
