hey guys my g/f got a `04 G35 coupe last october for her first car/18th bday present (yea not so bad huh?) well anyway i did the 1k oil change with castrol gtx 10w30, then the next oil change at 3k with valvoline 10w30 and just yesterday a 6k oil change with mobil 1 10w30, i figured by 6k miles the engine should properly be broken in enough for synthetic. the car has the VQ35 (3.5 V6) engine the nissan/infiniti uses in lots of their vehicles and i was wondering if 10w30 from mobil 1 is a proper weight to be using. the car lives in so.cal so it had mild temp. year around and a fair amount of city driving (make that mostly city driving) would 5k intervals of oil changes with mobil 1 be safe also? thanks for any help.

What viscosity is recommended in the owner's manual?
they recommend 10w30 and also 10w40 for warmer climates.
Looks to me as if you've done and chosen well. As someone today observed in a 'what have I learned' note, lots of us have differing opinions on what's the best oil brand, but M1 is a fine engineoil and will do well in that.
If she moves to the desert, use the 10W-40.

Well, in San Diego I don't think the W number is a factor at all. In that car and location, I'd probably run good synthetic 10w40, or if you can't find one of those, a 5w40. I'd think you'd want the higher high temp vis given the fact that it can get **** hot down there.
It might be a group III, but some people have been liking he Syntec 10w40. That would be about right in your application.

I've posted 3 used oil analysis to date using Mobil 1 5W30 in my G35 sedan. The results are far from excellent so I made a change in viscousity to 10W30, a slightly thicker oil. I'm in Florida so should not have been using 5W30 in the first place. I've got about 29600 on the odometer and a little over 7K on the current oil fill. I anticipate pulling a sample within 2-3 weeks, and will post the used oil analysis on the used oil analysis forum.
In the meanwhile, just search the used oil analysis forum for "VQ" and you will find a few good threads.

The best used oil analysis for this engine I've seen yet was with 15w40 Chevron Delo. Check it out in the analysis section. By the way, I hope your not buying the oil for here car! That would suck to but Mobil 1 for your girlfriend and then break up two weeks later
Syntec Blend 10w-40, ACEA A3 approved, better than Mobil 1 5w30 and half the price. Maintain mfg oci.
