Our contact information can be found at: https://www.castrol.com/en_us/united-states/home/castrol-story/contact-us.html **Q: will this work in a 2011 BMW 328i standard auto transmission?** A: Hi! For your BMW, we'd recommend using Transmax Full Synthetic Multi-Vehicle ATF or Transmax Dexron-VI Mercon LV instead. **Q: Hi! will this work in a 2014 infiniti qx70 standard automatic transmission?** A: According to Castrol’s Lubrication Recommendation Guide, Nissan Matic-S fluid is required for use in a 2014 Infiniti QX70 vehicle. Castrol Transmax DEX/MERC does NOT meet the specifications of Nissan Matic-S fluid therefore Castrol Transmax DEX/MERC is NOT recommended for use and should NOT be used in said vehicle. Castrol always recommends following the guidelines of the original engine manufacturer for the recommended fluid for use in your specific application. This information can be found in the vehicle's owner's manual or by contacting the manufacturer directly. Before using any lubricant, ensure that the lubricant product specifications meet or exceed the lubricant specifications required by the Original Equipment Manufacturer (OEM) for that specific use. **Q: will this work in a 2007 ford mustang V6, Automatic Transmission?** A: Thank you for contacting Castrol North America. Castrol always recommends following the guidelines of the original engine manufacturer for the recommended fluid for use in your specific application. This information can be found in the vehicles owner’s manual or by contacting the manufacturer directly. Additionally, for information on all Castrol products (motor oils, ATF, brake fluid, greases, gear oils), please refer to the Castrol US web page (http://www.castrol.com/en_us/united-states.html). According to Castrol’s Recommendations Guide, recommended for a 2007 Ford Mustang 4.0L 6 cyl is the Castrol Transmax Mercon V ATF, Castrol Transmax Import Multi-Vehicle ATF, Castrol Transmax High Mileage ATF, & Castrol Transmax Full Synthetic Multi-Vehicle ATF. Castrol Transmax Mercon V ATF, Castrol Transmax Import Multi-Vehicle ATF, Castrol Transmax High Mileage ATF, & Castrol Transmax Full Synthetic Multi-Vehicle ATF are suitable for use where Ford MERCON V type fluid is specified and may be used in your application. Castrol cannot guarantee compatibility with competitive fluids as we do not know their proprietary formula, therefore we recommend a complete drain of the transmission and re-fill with Castrol Transmax Mercon V ATF, Castrol Transmax Import Multi-Vehicle ATF, Castrol Transmax High Mileage ATF, or Castrol Transmax Full Synthetic Multi-Vehicle ATF. This should include draining the torque converter which holds about one-half of the ATF volume -- dropping the pan will not cause the torque converter to drain. You may find directions for draining the torque converter online, or may wish to have this service performed for you by a service facility.
