How about that the filter is rated to 12k miles...and has no expiration date.
But since you've decided to nit pick here, I will break it down for you and give you a precise answer. The OP went 6500 miles in 22 months. That is 295.5 miles per month. If the filter is rated to 12k miles (as stated there is plenty of evidence that this is a conservative rating) then the filter should be good for another 5500 miles. Given the ratio of miles per month, we get 18.6 months.
So to appease you, I stand corrected. The filter could easily go another 18 months and 18 days...
So, the answer to my question is "Based on simple math" which I understand. You're going on what Purolator says it'll go compared to what 440 ran it for. Fine. The filter has a 12k rating (I'll take your word for it) and he went about half that. Makes sense.
But... rated 12k on what? A showroom-fresh 2016 Toyota Prius that sees nothing but highway, or a 1975 Plymouth Fury with a clogged converter that has never had a tune-up? 440's 16 year old Jeep has a 4.0 engine design that dates back to the mid 1960's. Clean as it APPEARS to be, you would suggest running a synthetic filter on it that long just because Purolator put a 'one-size-fits-all' rating on the box? That's what I don't understand.
Sorry, I know I'm coming off snarky as **** but that isn't my intention. I just don't understand where many of you are coming from with the advice you're giving.
