Wow. That was a really good post. Took a little bit to read the whole thing but very very good info! Good researching SXYnerd!

 

If you only change your oil 1 time a year you should do it in the late spring early summer I think. I do it every spring in my truck. I could probably do it every 2 years with as low miles as I put on it.. last change i put on under 3,000 in a year..

 

Well Fellas
I change mine every 6 months/10K. One of my daughters owns a very new BMW, they only list 4 types of recommended oils 5W20. And 1 yr/30K changes, for her warranty she has to follow it. If your over your screwed. They are Caster Ultra Europe, BMW, Mob 1, and Val Extra. Yes it cost her 155$ pre change. But the filter is 30$.
Yes we are talking about f150s. I just thought I add what the high end 80K+ cars use. My wifes new Edge uses 5W20 and lists 10ks pre change.

 

I just wanted to say nice mustang in your sig. 71-73 never get enough Love.

 

That dude mostly talked about viscosity and its relationship to startup, operating, and racing conditions.

The only topic relating to this discussion would be the permanent thickening of oil due to "icy conditions," necessitating an oil change after winter.

Good read though.

 

Don't get all wrapped up in presenting some PHD on oils, you can't understand.
Ford does life tests during engine development and as an ongoing part of development for each vehichle application.
They test for metals, measure for excessive wear rates, make parts composition changes, formulation changes until they get the oil formulation for that family of engines.
A point comes when reasonable oil life change intervals vs expected warrenty and life is attained.
Ford oils are specified and formulated to meet these life cycles.
Other vendor oils have to meet the same standards to be allowed under warrenty.
Trying to out do the original oil specs, second guessing Ford, and listening to others about oil is an exercise in foolishness for a stock applications.
Changing to exotic oils after a motor has seen long life in an effort to extend it's life is equally foolish.
You can't make up for wear or even reduce it to any observable degree as an owner.
None of this has any good hard relationship to race engines or special applications where the oil/filter are changed very often to get dirt out.
Oil breakdown is usually not an issue but dirt, fuel contamination and high wear rates in a high cost motor is the important consideration long enough life and for winning.
Keep the perspective for all this in mind.
Good luck.
