Just before a track day I took my 06 coupe into the dealer to do an oil change with my own oil. I was going to have them put in Mobil1 5w-30 synth, but the service lady said that they don't recommend putting in synth oil until 15k miles (I had like 5k) because of some oil buring issues they've had with the coupes and if I put in syth oil, I "could have some warranty issues". Now I know a lot of you have switched to synth almost immediately, have any of you had oil burning problems? Is the service lady full of BS and should I just do the switch to synth myself? (btw - I ended up just doing a normal oil change that day, they use synth-blend and it cost ~$50!!)

 

I would wait until at least 10k miles.

 

i switched after 1k mile break in...

 

^I did the same after my first oil change at 3K. My car still runs fine.

 

if you think about it alot of high performance cars come stock with mobil 1 already...

 

i put mobil one in at 2700k.

 

I replaced my oil with mobil one also @ 1000 miles

 

My dealer changed my oil to Mobile1 at 3500 without a peep.
They actually recomend Mobile1..
Just remember to bring your own oil..its just too much at the dealer..

I'd like to hear what the dealer's excuse is for voiding your warranty for using synthetic oil. The only requirement as far as oil goes, as specified by nissan, is that it meets the API spec and is of the proper viscosity. As long as the API seal is displayed on the oil, and it's the correct viscosity, Nissan/Infiniti has zero ground to stand on by claiming you used the improper oil.

 

1) There isn't any real hurry to switch. The lady is probably more right than wrong to advise waiting.
2) But in reality, how would they really know? (if you had it put in somewhere)

 

Service people act like they know the world, honestly if there were issues you would see a huge warning in your manual like with the RX8

 

Wow!

That's a lot of miles...

 

I switched at 3K and no prob...so far at 40K

 

i got my first change done at infiniti of annapolis because it was free. the mileage at that time was 1k (3 months old). i changed to mobil 1 5w30 at that time. at my second oil change, a different service manager who has been a nissan/infiniti tech for 10 years stated that i should not use the mobil 1 i brought. i let him know that it was already swithed to synth. at the first oil change and he stated that should not have happened.

what he told me was that synth. oil does not allow the rings to seat, eventually leading to oil burn issues and poor mileage. he recommended i wait til 10k or 5k at the earliest. i switched back to conventional, taking his word on the problems he had seen in cars that had switched too early.
