Now dealing with diminishing mileage and replacing spark plugs. Perhaps it just age? What sorta MPG am I expecting with this sort of miles on it?
Why did you replace the drums? Mine had 60% life left at 125k without any previous maintenance (at least to my knowledge) when I got a rear brake service done at Nissan for $40. I'll be getting that done yearly. As for the mileage, if you're using the OEM spark plugs and changed them around 210k per the change interval, try changing the fuel filter, air filter if it's looking very grungy, throw a bottle of
Redline SI-1 fuel system cleaner in the tank, and if that doesn't help, perhaps the front O2 sensors are getting lazy and it's time for new ones.
I just broke 130k miles in my 2001.5 Pathfinder 2WD.
I recently had the oil pan gaskets and rear main seal replaced. This is the second time it's had to be replaced - first was at only 1,720 miles and covered under warranty, second was at 127,826 with a Fel-Pro gasket. Oil pan gaskets done at 128,072, and the rear main seal was replaced
again with a Nissan part this time (same shop for all that work).
Replaced both camshaft position sensors around 110k miles and a rear O2 sensor at 128,788 miles, but other than that it's just been fluids, filters, tires, and front brakes.
