For all you non-believers about 5w-20 Oil!
The following excert is from Police Fleet Manager, Feb 2007.......Please read!
" Some customers are reluctant to follow Ford's recommendation to use 5W-20 oil in it's CVPI engines based on the INCORRECT assumption that FORD recommends 5W-20 oil in order to increase fuel economy.......The 5W-20 oil is a thinner oil with lighter viscosity that creates less drag on the crankshaft,pistons & valvetrain. Additionally, the oil pump can pump thinner oil more easily, improving oil circulation. Machined internal engine parts are more precise than the parts of 20 Years ago. This means the clearances between moving parts are smaller & more exact."
" Thinner oil such as 5W-20 can flow more freely through the engine while still filling the spaces. Thicker oil is harder to push through the spaces between the parts. This causes the oil pump to work harder, which in turn increases oil pressure while simultaneously decreasing oil volume. A lack of oil volume results in a decrease of lubrication & cooling which may decrease engine part life."
I personally think that the engineers who designed the motor know more than the rest of us.............use what viscosity they recommed!!! Plain & simple!

This is a fleet manager with a degree in?...Not an engineer...
First...
If he is an engineer...He would have these tolerances and prove it...Or they should be available somewhere....There should be some data to support the claim...
Everybody claims that these nooks, cranny's and tighter tolerances get lubricated...Show the Data...
Now I didn't say 5W-20 is not a good oil....But I for one; hear a difference in my engine noise between the two...Much louder engine noise with 5W-20
I also don't buy that there is that much of a difference between the two to make any difference other than fuel economy....

By Ford also....No mention of nooks cranny's and tight tolerances....Economy yes...half of a percent.

Beyond Gasoline - High Mileage Oil
Who ever thought that engine oil could increase fuel mileage? If all U.S. consumers followed their owner's manual oil recommendations, about a half a billion gallons of gasoline could be saved each year. On top of that, starting in 2001, Ford led the industry by recommending the use of SAE 5W-20 motor oils in all light duty vehicles with the exception of 4.0-liter engines that use SAE 5W-30 oil.
Misangyi says that using 5W-20 can increase fuel economy by about one-half of a percent compared to 5W-30 and more if higher viscosity oils are used. This equates to an additional savings of 125 million gallons per year when used in all applicable Ford vehicles. Since its introduction in the 2001 model year, 5W-20 oils have saved up to 640 million gallons of gasoline in the U.S. or an equivalent 5.6 million metric tons of carbon dioxide emissions.
"The fuel savings for an individual customer over a year could also pay for an oil change," adds Misangyi.
Ford has also back-validated many vehicles made prior to 2001 to use 5W-20 motor oil. Check with your dealer or oil change supplier on whether or not you vehicle can use 5W-20.

SAE 5W-20 engine oil continues to be the only recommended oil for most Ford vehicles and the Mazda
Tribute. The Ford Engineering Material Specification for SAE 5W-20 service fill oils remains WSSM2C153-
H, which specifies ILSAC GF-3 requirements and the display of the API Certification Mark. In
addition, it specifies the double-length ASTM Sequence IIIF test. SAE 5W-20 oil provides our customers
with improved fuel economy and oil life performance. We continue to promote it strongly for our
customers and request the support of oil marketers to continue supplying SAE 5W-20 oils to Ford Motor
Company customers.
SAE 5W-30 is recommended for the SVT Focus 2.0L Zetec HP and 4.0L V6 applications, which are the
only gasoline-fueled vehicles not recommending SAE 5W-20. The Ford Engineering Material
Specification for SAE 5W-30 service fill oils is WSS-M2C205-A, which specifies ILSAC GF-3
requirements and the display of the API Certification Mark.

From what I've seen, to go from 5w-30 to 5w-20 is totally logical, here's why. I've worked in the plant where the 5.4's are built, nothing had changed in machining parts from the 5w-30 to 20 change so why not go with it. Gotta be something good about it. Take an engine built in 01 and one in 03 or 04, nothing different from an oil stand point, even engines today in 07 differ only in physical design from the 01 per say, like in pistons and block components. I haven't switched yet, but hearing more on this topic is tempting me to switch, it's got me thinking, whereas before I would just carry on with my 5w-30.

This has absolutely nothing to do with the engineers being smarter than consumers. It's an old argument full of engineering holes if anything. The simple truth is that Ford is responsible, along with every other major Mfg. to save natural resources, by federal mandate. They have no choice, they must play by the rules. Ford in return has passed that responsibility along to the consumer by specifying the use of 5W/20 motor oil. The fact that they are back validating older engines for 5W/20 should be proof enough. As far as what Ford fleet managers or engineers have to say on the subject, did you really expect anything different. If they said sure use 5W/30 they would be out of a job. It does'nt take an engineer or rocket scientist to see whats going on and why.

Its gonna take alot more than some fleet manager creating a straw man argument...What is he comparing tolerances to...A Ford 1966 292 engine? Well yea thats a no brainer...Or a Ford 2000 5.4 which was recommended at the time 5W-30 and is basically the same engine today. If it has tighter tolerances than in 2000 and NEEDS 5W-20 Show me the money...
When they back spec the the 5.4 before the oil was created...Doesn't sound to me like the engine was "Engineered for that particular oil"
Otherwise Believe it just because it is said...That is exactly what a dope does beside misspelling blessed
