Oil Weight

[4sfed]

Okay, I'm pretty sure I've seen this question asked, but I can't find it.

My question is....the owners manual says 5w-20 motor oil, the oil cap says 5w-30 motor oil. WHICH IS IT!?

I'm GUESSING the lighter one, but what does everyone here use?

Please note that I'm not trying to start a war with which weight or brand is better....I really just want to know which weight Ford meant for us to use in the TT engine?

TIA,
S

The 2012-2012 uses 5W-20.

The 13+ uses 5W-30.

What is your location? I've learned over the years to use OM as a guideline but go for usage. I live in CO so in the winter it gets real cold and 5w-30 gets real thick so I use 5w-20 in the winter, in the summer I drive my cars really ****** hard and its gonna get really hot, so in the old days you would use a thicker oil, however, the synthetics these days really don't ever break down, the only reason you replace them is cause they're dirty, youll see some fleet vehicles for ford and mercedes have like 20 and 30k mile oil changes

Okay, so our cars are oil, fluid.

I'm in the St Louis area, so I'll start adjusting my oil selection based on the season.

As usual everyone, thanks!

Yeah I'd recommend run it a bit thinner in the winter. Biggest oil recommendations i can make are pick a brand and stick to it for the life of the car, and use BG MOA in every oil change its a real magic sauce

I do not recommend changing weights due to season. Oil technology has made leaps and bounds. Once the oil gets up to temp within the engine there really isn't much if any variance in thickness anymore. Switching weights is a thing of the past.

You have to remember newer motors run tighter clearances ect. Throwing in a thicker oil then what is spec'd can cause lack of proper lubrication and premature wear on, components, seals, bearings ect....

Thats not quite true when you live in a climate that gets to -50 dude. Your oil will literally freeze. If you don't live in cold weather area you should just not talk about what you dont know.

Ok..... So all this leads back to my initial question. Which oil is correct. With the manual saying one thing and the oil cap saying another...

Okay if the oil can freeze, why would you put a thicker weight in it? It will can long to warm up and cause even more wear correct?

I didnt dude, I specifically said a lighter oil in winter when its really cold but in the summer there's no need to change because they don't break down like they used to

For the 2013+ cars the correct oil is 5W-30.

Here is some literature.

https://www.ford-trucks.com/how-tos/a/ford-f-150-how-to-choose-the-right-oil-359909

Note how they say.....

Ford specifies the weight (5W-20, 15W-40, etc.) and the specification that the oil must meet in the manual. The recommended oil weight is also shown on the oil fill cap. Some engines, especially diesels, specify a lighter oil in cold weather. This requirement is pretty much obsolete in gasoline engines.

If you live in a cold climate, your vehicle is or can be outfitted with a block heater. That will ensure that engine does not freeze.

Ford spec'd these motor for certain clearances. Please direct me to where Ford says to switch weights for different seasons.

You literally just said yourself dude "can be equipped with block heaters so they don't freeze" none of the SHOs have block heaters and i dont feel like spending the few hundred for one so ill just use lighter oil in the cold months

Shodded says go by your oil cap.

Can be equipped for extreme weather, however most do not need it. Also it says nothing about changing oil weight....regardless of climate. Ford knows more then you do about what oil weight you should put in your car.

Dude it specifically says the block heater is needed so that you DONT have to change the oil viscosity, are you stupid or something? You're sitting here arguing with me over something you clearly don't understand and have no business talking about. I've spoken with engineers at multiple manufacture INCLUDING FORD and most of them don't even bother testing different oils. They just go with industry standards for hp and displacement, i garuntee you that all the racing teams don't use 5w-30, oil is all about apication. so how about you take your uninformed opinions elsewhere.

First your statement is absurd with the -50 degree comment. That doesn't apply to 99% of SHO owners.

Second, a block can be used if you elect too. They are factory for cars purchased in the North because they are not needed.

Third, show me in Ford's Literature where they specifically tell you to use a different oil weight for climate reasons. in the 3.5 EB.

You haven't yet. You are spreading bad information. Thinner oil can do the same thing as thicker oil...properly not lubricate wear items. However you know that....

Dude I'm done wasting my time with someone that has the IQ of a nut. This discussion was between two cold weather climate people and i specifically stated why i ran the thicker oil in the winter and for the last time in that quote it says it "a block heater is available to keep it from freezing" ergo, without one it will freeze so without one use thicker oil you stupid ****

Wow name calling now are you 12? Lol

Again where does Ford say to use thinner oil for colder climate? Not an argument, I am asking for the literature there Bob the Oil Guy.

You are obviously 12 as I've explained it multiple times and you still don't get it.

You haven't explained anything. You say run a thinner oil in the cold. I say run the recommended weight in the cold. I showed an article pertaining to the 3.5 saying even in cold weather use the recommended weight. I asked for you provide literature from Ford saying use a thinner oil in the cold. You cannot provide it.

If you use a thinner oil, it reduces the film strength. That can cause increased wear, because the oil vacates the surface faster. Hence why you don't use WD40 for engine oil.

I got it, you clearly don't.
