How much oil does a 1964 Ford F100 Pickup need in an oil change?
The oil capacity of most automobile and light truck engines from the 60’s was five (5) quarts including the filter. If you are a little unsure, then I suggest that you remove and replace the filter, put in four (4) quarts of oil, run the engine for a few minutes to circulate the oil and then check the oil level on the dipstick. You will probably notice that you are low by about a quart. Add enough oil to bring the level up to the “full” mark on the dipstick. By the way, the 302 engine was not available in 1964. If the truck had a V8, then it was probably a 260 or a 352. These engines are relatively easy to identify and tell apart; but in any event, they both probably only use five quarts with a filter change.
If it’s a 302 Ford engine, it’s been transplanted into the truck since it wasn’t introduced until ’67. The 305 is a SB Chevy engine. If it’s an original FE block, it’s most likely a 352. Take a look at the intake manifold and see if it bolts to the heads under the valve covers – if so, it’s an FE engine. I think the best thing for you to do is to find a mechanic who is familiar with the early Ford engines and ask him to take a look. A truck that old may have had several owners and an equal number of modifications. It sounds like a fun ride – good luck.
