The worst problem the M-11 has ever had is head gaskets leaking coolant, so look for emulsified oil on the dipstick or oil fill or in the engine vent tube.
Fleetguard is the ONLY filter with stratapore... it is a synthetic filter media, and they have patented it. BUT, I do agree, big C gets fleetguard only.
The worst problem that the m11 has endured is main cap fretting. If I owned the truck, I would much sooner do a head gasket then replace (or line-bore) the block.
Besides, who doesn't have head gasket issues?
