The Nissan Path

Dear Pathfinder Friends

I am considering purchasing a new Pathfinder or Xterra. I am trying to research info on both vehicles. I felt the best way was to ask owners themselves. Can you tell me whether I would need to use premium or regular unleaded fuel ina Pathfinder? The salesperson says I could use regular unleaded but the owners manual recommends premium unleaded.

Thanks

Dan

I use regular but fill up on premium when going on a long haul. For the best performance, as stated in the owners manual, I recommend premium.

My '09 says the same thing. Recommended. I perosnally have not used mid-grade or premium yet. I have been using regular since the 1st fillup; have not experienced any performance issues at 13K miles on ODO.

I use regular pump gas most of the time. about once a month I alternate between a fill up of premium and the use of seafoam. not a problem as of yet

I just got an 2010, but only have 1100 miles on it. All 3 times I put Super in it, but was wondering if mid-grade would work also.

What do they mean "for best performance"? Spark knocking? Sluggish performance? What "might" happen if a lower grade is used?

Exactly that, best performance. When using premium fuel, the CPU wont retard the timing so much to avoid knocking therefore getting the most performance out of the engine. When using regular fuel, the CPU then retards the timing to avoid engine knock, pinging, detonation, whatever you wanna call it, therefore taking away some of the performance. Make sense?
If I'm wrong, please chime in.
