Passed smog so i will keep the X for a couple more years

Took it in today to get it smogged and the guy couldn't believe how clean it was running so he looked over the truck again trying to see if I am cheating.
At 25 mph (1760 rpm) it emitted 14.9% C02 and 0.1% 0.2%.
 HC measured 0 PPM with a max of 31 PPM allowed.
 CO measured 0.00% with a max of .73% allowed.
 NO measured 23 PPM with a max of 747 PPM allowed.

 Good to know it is running so clean for an 8 year old truck.

Wow that is very clean.  Mayber you're one of the lucky ones who got a very well built Xterra.  Mine passed smog easily also but not that clean.

Maybe, but I also baby my engine. I do have a volant cai and the nismo cat back exhaust.
 I change the oil and filter every 2700 to 3000 miles and I only use Castro GTX and the Fram Heavy Duty filter. If I run it hard or take a long trip towing my popup camping trailer (1400 pounds with gear and motorcycle) I change even sooner like 2000 miles. Small price compared to a new engine. Most of my driving is 6 miles to work and 6 miles back on PCH. X has 78,000 miles on it. I hardly put 8000 miles a year on it. Bought it 4 1/2 years ago used with 44,000 miles on it. Will admit it weighs about 300 pounds more from all the steel hanging on it,
ie; Gobi roof rack , schrock sliders, skidrow skid plates, full calmini lift etc.

I think with all that gear and armor, you're looking at more than 500lbs.
