I'm a little concerned about Ford's 5W20 oil recommendation. A 20 weight oil does not have nearly the film protection of a 30 or 40 weight oil which helps protect the moving parts of the engine. My concern is Ford's goal is to simply get people through the warranty period and they don't care if engines wear out prematurely down the road. In fact they may like that to happen so people will go buy a new Ford. Another factor is that a lower viscosity oil will provide slightly better fuel economy. With each manufacturer bumping up against the C.A.F.E. standards I suspect Ford specified 5W20 oil to help keep their fleet under the limit. Personally, I plan to use 5W30 Mobil 1 in my Freestyle. What are others opinions of this? - Chad

I actually saw the legal conformance letter the EPA and Ford both drafted (on the web). The EPA allows the 5w-20 spec on the condition that Ford print "5w-20" on the filler cap and specifiy it in the owner's manual with no wiggle room in their language. Mobil 1 is a good choice, although I'd use Castrol Syntec 0w-30 (has the 30 weight high-temp film) but flows better when cold due to the 0w part. That brand and weight are available at Autozone. That oil is famous for better performance specs amongst all known oils ( google german castrol syntec for more information). Its known as German castrol because it is made there and people in Europe, who change their oil once a year and drive fast on the autobahn, use it.

Replying to: passat_2002 (Feb 10, 2006 5:01 pm) In my opinion putting 5W30 full synthetic oil in my Freestyle has the upside of better protection for the engine with little or no downsides. By going with a full synthetic the minimal additional fuel economy gains of a lighter oil are negated. Maybe it just helps me sleep better at night but I guess I feel why wouldn't you? - Chad |

American areas, its better to use a 0w-30, like Castrol Syntec 0w-30 sold at Autozone, and some Walmarts. The 0w part says it will do the best thats possible at winter temperatures when starting up. The 30 part says it won't thin out quite as much hot as a 20 would. That said, most people would still be OK with Mobil 1 5w-20. Its only the people who want a slight edge that will go with 0w-30 Castrol Syntec.
