STATED MILEAGE (HWY ) IS 22 MPG , THE FIRST SIX MONTHES OF DRIVING DID ACHIEVE THIS STATED MILEAGE ,OCCASIONALLY  AS MUCH AS 23 MPG .AFTER 2 RECALL SERVICE VISITS AND AN OIL CHANGE , THE MILEAGE ABRUPTLY DROPPED TO 18 MPG I COMPLAINED TO CHEV. SERVICE IN COTTAGE GROVE ,OR SEVERAL TIMES OVER THE COURSE OF 4 MONTHES THEY ADVISED ME TO CHANGE FUEL (SERVICE STATIONS ,) PUT A FUEL BOOSTER ADDITIVE IN THE TANK ,CHECK TIRE PRESSURE .THEY ALSO STATED THAT THE FUEL MNFRS.  CHANGING THE FUEL BLEND FOR THE WINTER SEASON MAY BE THE CAUSE. NO SERVICE CODES IN THE COMPUTER . NONE OF THE SUGGESTED \"FIXES\"  HAVE CHANGED THE MILEAGE ,STILL AT AROUND 18 MPG .  SOMETHING CAUSED THIS SUDDEN DROP IN MPG .I HAVE A COUPLE OF IDEAS ,   1. ONE RECALL WAS A COMPUTER SOFTWARE UPGRADE ,WRONG SHIFT PARAMETERS INSTALLED ?  2. AT PRESCRIBED OIL CHANGES ,06/03/14 &12/18/14 , ( TRUCK REQUIRES DEXOS 0-20 OIL ) MAYBE WRONG OIL WAS  INSTALLED ? ONE INVOICE SHOWS 5W-30 WAS INSTALLED .  HOWEVER DEALERSHIP DENIES INSTALLING WRONG OIL .  HOW CAN I HAVE THE OIL ANALYZED TO DETERMINE WHICH IS IN THE TRUCK ?   *JS","products":[{"type":"Vehicle","productYear":"2014","productMake":"CHEVROLET","productModel":"SILVERADO","manufacturer":"General Motors, LLC"}]}]}
