Which motor oil should i use
Hey all I have 2011 F150.
Which is the best motor oil to use? And, How much does it take to fill the engine up after i drain all the old oil out?
Thanks,
Cam

Cain't go wrong.
Wait, you (not "you" personally) can go wrong! Not if you follow manual, but I just borrowed a Ford van, supposed to use 5w-20 oil, but they take it to some kind of quick change place and they use 5w-30 oil in it! I say NEVER go higher viscosity that the upper number, but you can go a bit lower, e.g., 0w-20, which is wha' I use in me '02 5.4. Full synthetic for me.

What oil ?
I just love these post's regarding oil. I work for a company that owns probably the 2nd largest fleet of trucks in the country next to UPS. They buy new trucks and the oil cap on all the trucks presently in use say "5W/20. Well....... when these trucks get their first oil change in goes the heavy duty 10W/40. The same oil that is used in their diesel fleet. These little Chevys and Rangers run 300,000 before they are sold and never.....I said never have engine problems. Normal front end wear, and tune ups and that is it. I saw one the other day with 323 thousand and it gets run hard every day. Sounds good and runs strong.
Oh......one other thing. This company uses the same oil in Florida, Arizona and in the Northern States as well. So....now somebody, please don't tell me that you need to use that 5W/20 sewing machine oil or ELSE.
May I add that 6000 miles is the change interval.
My personal oil in my Crown Vic is 5W/30 and has been since new. 156,000 and runs fine every day. My new 2014 STX with 1800 miles is in line for it's first change....guess what .... 5W/30 Syn. No sewing machine oil in my engine.

There is a thing called Google. You type "2011 F-150 manual" and the first listing on the page leads you to...

This "sewing machine oil" concept is truly funny. Not sure how a lower vis oil is such a bad thing. The base oil is one thing, but the add pack in an oil has as much to do with how well it performs. There is no evidence that using a low vis oil is a problem. Even commercial heavy diesels at going lower vis. Detroit is now factory filling their DD15 15L heavy diesel with 10w30, and has a OEM recommended oil change interval of.... 50,000 miles. Chevron has tested their 10w30 and 5w30 oils in these same engines with ample evidence that the oils hold up well to 70,000 miles. And these type of engines would traditionally get a 15w40 HDEO and are regularly powering trucks and load of up to 80,000 lb gross weight from Canada to the Rio Grande. From the Arctic to Death Valley in the summer. A lot of commercial trucking fleets are shedding the 40w game for 30w oils.
Why a 20w wouldn't hold well in an engine is old school. There is a present standard being developed that will move toward a 16w oil for a vast majority of engines. There is some pretty good characteristics to lighter vis oil in modern engines. Component tolerances are tighter than ever, and a lighter vis oil guarantees a more uniform film layer across the contact spectrum, especially under high torque loads. Also, a lighter vis fluid will shed accumulated heat faster than a higher vis fluid, i.e. water will shed accumulated heat faster than cooking oil. Simple physics. This is especially a consideration in turbos.
And the broader the range of cold flow to oil viscosity required more viscosity improvers (VI) to meet the range. i.e. a 10w40 requires more extensive VI than a 10w30. Same for a 5w30 compared to a 5w20. VI's are more prone to shearing than base oil, and a resultant viscosity loss and decreased oil performance can result.
There are many good reasons that OEM's are spec'ing lower vis oils. It is easy to accuse the EPA and CAFE standards behind all of it, and there is definitely their interest being considered, but the OEM's have a lot at stake. It is their wallet that gets affected by warranty issues and such. If the lower vis oils weren't more than up to the task, you can bet the OEM's would not recommend them. Base oils and add packs are significantly more advanced than in days gone by.
