This new 5W-20 motor oil is really confusing to me. I thought 5W-20 was only to be used in really cold climates (aka the Yukon) and never at freeway speeds. I guess Ford is building to tighter tolerances and needs an oil to get between those tight spaces. Anybody heard of any problems with the new lighter 5W-20? Just curious.
Massachusetts - 2002 XLT V8... I use motocraft 5W-20 synthetic blend(manufacturer's recommended oil) in the winter and switch to Mobil 1 5W-30 in spring, summer,fall. Always using Motorcraft oil filters. I change oil every 3k (give or take). Doing this since 0K and have 20K now and still purrs like a kitten.
I know all have their views on oil, I just thought that for the 4.0 V6 in many of our Exporers that 5W-30 was the recommended oil. This engine is one of few that does NOT rate the new semi-synthetic 5W-20?
Of course when it's all said and done will it really make any difference if you try it? You got me.

Ran into this thing when I owned my 02 Cobra in a post on stangnet. Someone over there got hold of a leter from the Federal government, (EPA I think) That was addressed to auto manufacturers in general and posted it. It said, in a nutshell, that All manufacturers were to change their recomendations for oil viscosity to comply with less hydrocarbon production and to achieve greater fuel economy. What that means is, they don't care how long your engine will last, as long as it is good for the environment. Ford isn't making engines any tighter than they have in the past, they just want to squeeze more mpg out of them. (lighter oil, less resistance, but also less protection) I wish I could dirrect you to that post, but its been a long time. You could try stangnet.com and do a search.
The Home mechanic talk show recommends staying with OEM through warranty period and then switching to a 10w40 here in this hot Texas weather. Their are some engines that must use a 5w but I don't think they are ford's. He also, highly recommends going to a synthetic if planning on keeping a vehicle for years but even with synthetics do regular oil/filter changes.
So bottom line it depends upon the climatic and temperatures that you are operating in.
