Hi, new to this forum but glad I found ppl that love their Frontiers as much as I love mine! I have a 2001 Frontier Road Runner and I bought it in 06 from the original owner and it had 118K with no problems. Since I've had it; it now has 260K miles on the engine. I've never had any real problems .. it's a super strong truck that has taken me off roading to places that even I was surprised it made it. The only work I've had done is replacing the timing belt and water pump and I just replaced the original clutch. My question is how many miles have you other owners put on the engine? Are they known to last a long time? Has anyone ever got over 350K miles?
