I have a 2005 Ford Escape 2.3 litre, 4 cylinder, automatic transmission. The owners manual states to use Mercon in the transmission and the power steering. I went to Advance Auto, they did not have Mercon, but had Multi-Vehicle Automatic Transmission Fluid suitable for transmissions requiring Dexron III and Mercon. I bought this and added a few ounces to the power steering. I know that Ford has done something with the licensing with Mercon, and is switching over to Mercon V. My questions are this; 1) Why does my 2005 Escape use Mercon, but my 1999 Ford Ranger, 3.0 litre V6, automatic transmission uses Mercon V (and Mercon in the power steering). 2) Is it OK to use the Multi-Vehicle ATF in the Escape transmission. 3) I plan on having the Escape transmission flushed this fall. If I have it flushed at the Ford dealer will they switch over to Mercon V? Also, if I have it flushed at a "Jiffy Lube" type place what might they use. 4) I read a bottle of Mercon V at Advance Auto, and it stated that Mercon V could be used as a substitute for Mercon, but the Escape owners manual says not to mix the two. 5) It it better to use Mercon in the power steering, or actual power steering fluid? I know these are a lot of questions, but taking care of a vehicle sure can get confusing. Thanks.
