24 oz
Can't give an answer without knowing the model.
The 2005 F150 5.4 L 3V engine takes 7 quarts with engine oil filter change , according to the Owner Guide
Under the hood on the truck will be a label that lists how many ounces the truck requires. You can then compare to the amount in one can to decide how many to use.
R134a
I just checked with the local Advanced Auto in town and they said it takes 18 ounces of freon and 4.5 ounces of oil.
R-134a
The system will take 30 ounces of R134a freon.............
1.88 pounds of 134
It's been a while, but I believe its 2.2 pounds. The R-12 for this will be prohibitively expensive and hard to find, consider a 134 conversion kit.
All of the newer vehicles take R134a.
1.6
It depends on the year and witch type of freon you have but on a 2003 model it will take 1.6 pounds of R134a freon................
