In the Fiesta ST supplement it lists 2 equivalent oils: XO-5W20-QSP (US) and CXO-5W20-LSP12 (Canada). When I first picked up my car, I also bought a case of oil and a few filters with the part numbers I found online. The dealer gave me XO-5W20-QSP Synthetic Blend Oil in red bottles. Fast forward to earlier this week, I go to another Ford dealer (closer to work) to pick up some more oil and filters… They say they have no idea what “Synthetic Blend” is and gave me CXO-5W20-LSP12 Ford Premium Oil in black bottles. Anyways, after a brief argument at the parts counter, I left with the oil, satisfied that it was referenced in the manual but confused by the parts discrepancy. I used the “Ford Premium” oil yesterday and I noticed that it appears to be a slightly darker colour (or it could have been the bottles). I assume they have both been certified by Ford for use in the FiST. What oil are the other Canadians putting in their FiST? Has anyone else found Canadian dealers carrying US part numbers?
