FL-400S vs FL-1A
Is anyone using the larger FL-1A instead if the puny FL-400S on their 4.2L engine?
I was changing the oil on our 4.0L SOHC Explorer last week and it looks as though they are interchangeable. The 4.0L engine uses the FL-1A and it seems that both filters have the same tread size and gasket diameter but the FL-1A is much larger. It holds almost a full qt of oil, whereas the FL-400S only holds about 1/4 qt.
I thought with the FL-1A, I'd use a full 7 qts instead of the normal 6 qts.
Just asking, in case someone else is already using this filter...
