I've got around 1200 miles on my '10 G37 and have yet to take it in for an oil change (I bought it in April). The service manual recommends 3750 miles/3 months for Schedule 1 service and 7500 miles/6 months for Schedule 2. I'm thinking of going with Schedule 2 since the car is driven in good conditions and not exposed to harsh temps.

I don't know what type of oil they used when I first bought the car (I'm assuming standard 5W-30 oil and not Ester oil). I know that engine oil loses its viscosity over time, but is it still too soon to bring in the car for it's first oil change?

 

if you bought it used, just change it. you can start switching up to a full synthetic blend oil.

 

I bought it new. I just don't know how long to wait until I bring it in for it's first oil change...

 

3000-3500 is usual time for the first change

 

^ what he said. and then continue to change the oil once every 3,000 miles or 3 months like the manual recommends.

 

I actually go 8K-10K miles between oil changes (on a full synthetic) but for the first one I always go 3000 no matter what and swap out the factory oil for full synthetic

 

I am going 7500. I have been doing UOAs after each oil change to see how the oil is doing. Now with Pennzoil Ultra, I seem to have it going well.

 

I plan on changing mine every 3750.

 

i did mines right on 3750 from the start. now i'm doing it right at 3k

 

I also use full synthetic (mobil 1) but in general I think the timing for changing your oil depends on how you drive the car; people who drive more aggressively should change their oil more frequently.

As for me, I don't really drive aggressively that often but I like to change the oil frequently every 3K miles or so....just to be on the safe side lol. plus I do my own oil changes in 10 minutes so it isn't really that costly or that big of a deal to me. I learned everything from my dad and he's maintained a honda for 18 years, a maxima for 16 years (and counting) and a mercedes for I think 12 years (still running) so I put my trust in his teachings lol.

 

I used Mobil1 for 10 years and have recently switched to Penzoil Ultra to see how it works. Both are great oils!

 

Damn, 8-10K between oil changes? Pls let me know what you are using, I need some of that.

 

Read my post just obove yours lol #11...Mobil1 until this most recent oil change. I had roughly 21000 on Mobil1 and have about 5500 on my current run of Penzoil Ultra

 

Just so you guys know the quality of Mobil 1 has come down a LOT in the past couple of years, its still good oil but I would not let it go past 5k in my car. A lot of guys on corvetteforum.com (my other car is a 540HP Corvette) do a oil anaylisis on their mobil 1 and have seen the changes.

 

There are UOAs on a number of oils in a sticky thread in this very forum, including two I did with Mobil1 and one with Pennzoil Ultra. From my results I will not be using Mobil1 in this car any more. I won't go beyond 7500 miles right now because I do not want to chance having to some day fight with Infiniti over a engine problem possibly being caused by the oil. Once the warranty is done I will move up beyond 7500. At the rate I am going it will be sometime near the end of next year.
