Went to the local dealer Wed to inquire about an oil change at 1700 miles. Told the Service Writer Matt I want full synthetic . He asked if I bought the truck there, no I replied. I stated the selling dealer gave me a 3 yr, 6 oil / tire rotate plan and would there be any charge. He replied, " Maybe fifteen or twenty bucks" . Fri morn I bring it in f/ appointment. Another Serv. Writer starts the paperwork as the "Matt" is on the phone. I inform the other writer I wanted it to be full synthetic. He acknowledges from the paperwork filled out Wed. Once its completed, I go in the the other writer says "You're all set, no charge, thank you " OHH...OK I said. I'm thinking what plan did the selling dlr give me. Seems like a myriad of different plans, price, tiers, ect. At home, I'm looking at the paperwork f/ the dlr and can't see wwhere it says " Synthetic" So I call. The other writer answers and I ask him, what maintenance plan do I have ?? He says I get two free full syn oil changes, they "give" it to you when you buy the truck. Huh ?? I have 6 oil changes. He starts researching and says " Oh, you didn't buy it here. The plan you have is basic. We really appreciate your honesty, you owe us 50+ dollars" WHAT ?? Excuse me ?? You " appreciate my honesty ", pay us 50+ dollars. Hmmm. I thought I might have had the Super Duper Maintenance plan, or maybe I owe them upwards of twenty dollars. Hope they don't "appreciate my honesty" much more, I'll go broke.
