I bought one for my '15 after 1st oil change or 2 as the drain plug for the oil is in RR corner on the side of oil pan. NOT a Ford better idea. Anyways, if I recall right, I measured the factory plug, then ordered thru Amazon. So my question is, I'll be due for an oil change after our vacation and would like to replace factory plug w/ a Fumoto valve at that time. How do I go about getting the right size valve ahead of time?
