Is there such a thing as break-in oil? I'm about to hit 1000 miles and was planning on changing the oil for the first time this weekend. I'm going to wait a while longer before switching to synthetic so I was gonna put in a good conventional...Castrol GTX or Quaker State. In my mind it makes sense to change the oil at 1000 to get anything that might be in it from the break-in out. But I've also read that the oil that comes in the engine should be left in for longer than 1000 miles because it's the "break-in oil". Is there anything special about the oil that comes in a new engine that makes it better than Castrol GTX or Quaker State? Thanks.

 

I just dumped mine yesterday with 1200 miles on it and switched to full synthetic with synthetic filter...car runs better and smoother

 

Some manufacturers use 'break-in' oil, others don't. My volvo cross-country got its first oil change at 7500 miles, my (former) honda said they "could void the warranty" if you changed the oil before 3750. Nissan doesn't use those oils/additives so change at 1,000.

 

you'll be just fine if you wait until the first 3,000 mile oil change...

Hey dude whats up, Did you get my P.M?

 

Yeah... just been busy at work, amigo... I will answer soon!

 

Nissan does not use breakin oil.. early oil change is actually a filtration issue, not the oil.. the new oil filters are tiny, I would probably do an early change for that reason only..

 

Thanks guys!

 

I'm changing mine at 1k miles. Will go till 5k before synthetic goes in. This is what I did on my 2k1 and it runs like a champ and hates the taste of oil.
