Mr. Irwin, we apologize if you feel as if you have been over charged but I would like to assure you that your 2014 GMC Sierra 1500 SLT truck with 5.3L V8 engine does in fact require 8.0 quarts of 0W20 dexos1 oil. Here is information from GMC as quoted: "Engine Oil - Volume: 8.00 QTS. (7.6L) - API - SAE 0W-20; 5.3L Eng - w/Filter - (Note: Use only engine oil licensed to the dexos1 specification, or equivalent.) NOTE: The engine oil capacity has been updated from 8.50 qts to 8.0 qts in reference to GM's Document ID: 3998244, #PIP5231A.) In fact as part of every oil service, after adding oil, technicians are required to check the oil level in order to make sure that the correct amount of oil has been added, and report/update the repair order accordingly. If for any other reason you are still dissatisfied with the service you received, please give us a call and we will be sure to meet or exceed your expectation. Customer satisfaction is our number one priority and we look forward earning your future business.
