F150 oil capacities

[Kirk Gibson]

OK this may have been discussed before but I have twin F150's.
One is an 2008, the other is 2010. Both were installed new.
They seem identical in every way and today as I was changing the oil I noticed the 2010 engine says 4.7qts. with filter on the cowling. The 2008 says 5.5qts.
Now I always fill and check to be sure the final level is BETWEEN the hash marks on the stick (as per the manual) so I guess it doesn't matter too much. Just for kicks I stopped at 4.7qts., ran it for 5 minutes, waited 5 minutes, did the tilt forward and back, waited again (probably not necessary) then checked level. It was at the bottom mark. So I added a little to bring it to the mid point.
When I filled the 2008 with 5.5qts. and checked in the same manner it settled right at the mid point.
Anybody else ever ran into this?
What did Yamaha change between these 2 years to make the 2010 hold less oil?
Thanks

As I re-call, my '06 F150 owners manual says 5.5 Quarts.

The last two times I bought oil and filter, the shop says its takes 5 quarts, period.

At 5 quarts, its barely touching the bottom of the hash marks. Another half quart brings it to the middle of the marks (testing just as you have).

I make sure I have 5.5 quarts on hand when doing the oil change with filter..


From my Yamaha SHOP MANUAL
(5.7 quarts with filter)

I remember in the old days when cars needed regular topping with oil. The dipstick marks were a quart apart, the middle being 1 pint from the bottom (or down from the top).
However we only had imperial quarts not US quarts then, but had cars made all over the world. I guess it was just an approximate thing then. A racing friend used to find "the sweet spot" on his dipstick where he believed too high meant more resistance and oil usage, so he would religiously test where this point was!

still

Still wondering why Yamaha had 2 different amounts listed on essentially the same motors?

Was there a tech update that suggested only filling to halfway point between marks? Mine is full.....Is that wrong? 2004 F150TXRD... Uses zero oil after 11 years

[Kirk Gibson]

Going by manual

Just going by what the owners manual states and that is between the marks.
I guess they are allowing for expansion so I have always (on these motors) filled to midway between the marks.

Does oil expand?

[fairdeal]

virtually all matter - solid, liquid, gas - expands with increasing temperature

but I think Yamaha makes their dipstick recommendation due to the variability of how the dipstick can read- engine tilt, side-to-side incline, "hangup" within the engine parts etc.

How about that water? Contracts with the lowering of temperature and then at some point expands with the lowering of temperature.

yes, the classic exception - for that narrow range just above the ice point.
There are a few others, but not, I think, that we encounter in daily life...

How about CO2? I still am having trouble getting my mind around sublimation.

We can have frozen CO2. We can have liquid CO2. We can have gaseous CO2.

Seems that frozen CO2 (solid) must have to turn into a liquid before turning into a gas even if it is but for a nano-second. But obviously not.

[TownsendsFJR1300]

I've got into pissing matches with the parts people on how much oil I need.

I know how much it takes to bring it mid hash marks, been doing it 9 years myself...

If you look on-line (or sometimes at the marina), there's an oil change kit that includes a filter, drain gasket, and 5 quarts of oil, (not 5.7 or 6)

Leave ice in your freezer long enough I will "evaporate" without going thru liquid phase due to below freezing temperature in the freezer, the everyday example.

Still wondering about my original question, why would Yamaha put two different volumes on two engines identical but two years apart?
Yes I know how much I need to get it between the marks etc. but wonder what made Yamaha decide that the 2010 was different from the 2008 oil volume wise?
Thanks again

This principal was used to split large rocks: pour in water into crack then leave overnight for freezing temperature, turns to ice then rock splits. Nature did this on its own and explains certain large rocks and formations.
