Never use 5w-20.
20 is to low. It protects ur car like water wen it gets hot it thins out to much.

Re: oil question

Spec for my 3.8L is 5W30. I have about 220,000 miles on the engine now and i just use 10W30 in summer and 5W30 in the winter. Mobil1 Extended Service is what I have run for the last 100,00 miles+. That and a Mobil1 oil filter. Sometimes a K&N oil filter, and sometimes a Motorcraft oil filter. Depends on where I am when I pick up the oil.

Re: oil question

Just some FYI for anyone interested:
Amsoil Signature Series oils are guaranteed 25,000 miles or one year which ever comes first,
Royal Purple has a redesigned oil filter far superior than anything on the market now and can be purchased from American Muscle cheap and free shipping.
Just some info, hope it's useful to someone out there!

10w30 won't hurt your car at all. Its not much thicker than 5w30.

You can prop up your hood and the recommended weight is there. If you feel your seals are wearing, upping it by 5W in the summer won't hurt. If you can keep it running with 5W without noisy lifters, do it. A good Seafoam treatment to the upper intake manifold does wonders.

You can change over to synthetic at anytime as long as you do not have any oil leaks presently.

If there is already a leak present, then it will leak more because of how slippery the synthetic is. It will find its way out of the engine quicker. Synthetic oil is cheaper to use than carbon based because of the longer change intervals. It gives Superior protection for the engine and is cheaper to use in the long run.
Six quarts of the Amsoil will cost $35.00 and last 12 months. Six quarts of conventional oil will cost $12.00 X4(change every 3 months)=$48.00 plus the time, effort, and dirty oil that has to be disposed of properly.
Understand?

If Ford recommends 5W-20 for your engine, then you are already using some of the best possible oil+filter to keep your car running for a long, long time. Clearance tolerances can not tolerate more than 5W weight oil without causing damage to the engine.
Contact someone from Ford and ask. Preferably not a local mechanic at the dealership. Google and research someone with Ford that works in the engineering/development department. they will tell you the same and explain better than I can.
-Royal Purple is great stuff
-K&N oil filters are of the highest quality.
You are doing just fine. Consult your owners manual.

Motor Oil Viscosity Grades Explained in Layman's Terms

I thought this explained what the difference is in the viscosities real well....and what i got off of it is it doesnt matter if its 5W or 10W it wont hurt your engine....the main one is the last number... you want it a little higher. the 5 or 10W just tells you how easily it will start moving around parts when the engine is cold or in a colder enviroment

What I understood is that newer engines that get better compression ratios can tolerate and maybe prefer the lower weight oil. Older engines actually need the heavier weight.

For my wife's car (1999 Ford Contour 2.5L V6), she has ALWAYS had 10w30 put in. The last oil change saw some dufus put 5w20 in, and we witnessed major engine trauma two days later. Coincidence?

Re: oil question

I run 5w-30 instead of 5w-20, after reading MANY articles and much research 5w-30 protects better and works great~ the 5w-20 was only used for emissions and is a thinner oil and thus does not protect quite as good. Its still within tolerance on my car to run 5w-30.
