Thanks to everyone on the site for posting so much awesome information......the VX had its first oil change a few weeks ago, the wife has been driving from SE PA to NJ for job training..........with all that in mind......I have been really watching the oil........before she left on Tuesday morning, I checked the oil and told her to take the Frontier........told her why........

here, the VX was down over a quart in little under 1000 miles.........

I did not have the PCV valve changed out--- that will happen from here on out with every oil change.....

new owner.....the vehicle is in great condition...but, when I bought it, a spark plug was cracked and it was running like crap....replaced all the spark plugs and it ran fine.......

my mechanic explained what to look for--blue smoke when starting up (PCV) vs. smoke coming out the exhaust when I lay off the gas while going downhill
(bad rings / valve guides)

plenty of smoke when starting up--not sure if was BLUE or just grey because it is cold out.......but I didn't see anything out the side mirror when I let off the gas pedal going down a hill

then after searching the site......I came across the EGR valve? still not sure what that is....but reading all the info gave me a headache !!!

would my best bet be--since I am a new owner--and mechanically the vehicle may not have been best taken care of--- I should do what??

currently there is 96740 thousand miles on it......Oil change sticker says 99080--- so, it was't driven all too long before noticing some oil was missing...I'd say a quart and a half? or just over a quart......

I'm not a mechanic.........not even close.......I can check the oil and other fluids and fill em up if needed......but that's about it
