The reality is that there is no appreciable difference in the amount of oil filtered by the two types of filters.
Figures I've seen show that the canister type with the replaceable paper element filters about 87% of the oil whereas the spin-on type filters 92% of the oil under the same conditions/engine hrs.
For pampered vehicles like ours that aren't pushed to the limit and whose oil is changed frequently (3 mos, 3000 mi), you are not going to notice any difference in your lifetime.
With that said, do I want a larger canister like that used for the bigger 261 vs the 235 engine?
I have seen oil canisters listed as "Heavy duty"(larger in height) over the smaller 216/235 type(smaller)... or at this point would it just be what looks best in my engine bay?
