Hello! I'm a new Pathfinder owner and I'm glad I found this forum - I bought a 1992 pathfinder 4x4 for winter usage, and was wondering about the gas mileage. It's about 19 MPG - which seems a little low for a semi-modern 3 liter engine (trans in 2-hi). I got a tune-up from a local garage, and the mileage didn't change. There is an intake-manifold whistle which is related to the throttle position: It changes as the throttle opens, and goes away at over half-open. I replaced cracked tubing which I found - but the mileage didn't change. Is this normal (I saw on another forum that Nissan's have this issue maybe?)
Is 19 MPG about right for this car?
Also, what is a reasonable usable-RPM range for this engine? To cruise at 70 MPH takes the RPMs to about 3200 or so, which seems a tad high (although well below tachometer-indicated redline).
Thank You Very Much!
Patti
EDIT: About 175k miles and recently had timing belt and tensioner(s) replaced. Significant lifter noise which goes away after they fill with oil.
