5w20 question
I have a 2002 Edge 4x4 reg. cab with 3.0 manual. I have over 4,000 miles on the engine and I'm getting 21 to 22 mpg combined. I drive mostly 4 lane to work, with a few red lights along the way and I use speed control where possible. I run the truck up to between 3,500 to 4,000 rpm between shifts when accelerating. This has all been with Motorcraft and Castrol 5W20. This is 1 or 2 mpg better than my '97 3.0 manual 4x4 got running 5W30 and 10W30. Not sure if its the oil or the truck itself that's giving the improvement.

5w20 question
[updated:LAST EDITED ON 08-Jul-02 AT 02:40 AM (EST)]I am a ford tech at a northwest dealer, we just got a message from ford that they recommend this 5w20 blend for most of the line back to 93/94. not all vehicles were included in this recommendation though. personnally I will not use it in my 100k plus 1994 vehicles but would recommend it in any vehicle that it is recommended for. I have heard of some 4.6 engines having 10w30 in them and blowing gaskets and filters all over.
just my two cents worth,
Jim
P.S. besides the motorcraft 5w20 blend is $1.12 verses castrol at $1.30 at Walmart(wallyworld). and I'm surprised at any dealership that does not use the motorcraft oil.

>achieve the EPA rated gas mileage on the window sticker.
Somehow, the US manufacturers have figured out how to cheat the test. Most imports get equal or better than the EPA estimates in real-world conditions, the US cars and trucks worse.
My '94 F-150 5.0 gets 12/16 real world, 15/18 is the EPA est.
My '92 BMW 325i gets 22/29 real world, 18/26 is the EPA est.
Both are stock with over 100K miles and use 15W40 Delo oil. Same driver. Same exact routes for my tests. Arco, Chevron or Shell gas (premium for the BMW).
The 4.3 GM truck that I used to have also got less than the EPA (14/19 real, 17/23 EPA).

That is actually very untrue. Consumer Reports recently did a comparison test with a bunch of import cars, and they got worse gas mileage than rated. For instance, the Acura 3.2 TL Type S was rated for 20-29, yet they only got around 18 in the city, and 22 on the highway. Same deal with the other vehicles. You are only going to achieve the epa rated gas mileage under the most ideal conditions which excludes 99% of us.

My wife and I must be in that elite 1% that drive in the most ideal conditions. My 1993 Ranger (2.3L, 5 speed, 130,000 miles) is rated by the EPA at 23/28. I usually get 24 - 27 mpg while commuting 60 miles each day on a city/highway combination of roads. I recently had a 600 mile trip (all highway) and got 29 mpg at 65 - 70 mph. Our 5.4L Expedition is officially rated at 12/17. We get 14 - 18 mpg around town/country and averaged 22 mpg on a Detroit to Cincinnati trip in May. Must be our driving styles, as we've always gotten at least the EPA numbers on any vehicle we've had. We were wondering what kind of mileage we were going to get with the Expedition, but have been quite pleased with it's "relative" economy so far.

New engine do have tighter clearance but the MAIN reason the OEM oil is so light is to improve CAFE fuel milage figures. Even a .2MPG improvement per vehicle can add up to a huge increase in their overall average which is mandated by the goverment.
In a hot climate I'd start using a thicker oil as you build miles and operate in hot climes. Synthetic (any brand) is definetely slicker.
