Went in for their special 19.99 oil change and tire rotation. Immediately I was told I needed the synthetic motor oil change (now 49.99) AFTERWARDS, I looked in my owners manual and on page 354 it says, "You may use a synthetic motor oil if it meets the same requirements given for a conventional motor oil: it displays the API Certification Seal, and it is the proper weight. You must follow the oil and filter change intervals shown on the information display" -- In other words, I did NOT have to use synthetic! Of course they nit picked apart my car and came up with my cabin and air filters that needed changing. They were dirty, so i reluctantly agreed. Little did I know the cabin filter I was sold for 49.00, you could have bought at O'Reilly's for 18! They charged me $19 for an air filter that I could have bought for 12! NEVER again will I go to or recommend this rip off joint.
