G35 2006 egine oil change interval

[QX1]

hi
can anyone explain me why G35 VQ35DE oil change interval is 3750 miles and same car Nissan 350Z oil change interval in Europe is 15000km or 9400 miles? Same engine basically?

That's interesting. I've never heard of that, do you have any documentation that's showing that's the case (it's not that I don't believe you I'm curious just for myself)..

As far as I know the only difference would likely be in the emissions system (probably the cats).

As everyone seems to have different ideas on when servicing is due and what it comprises I thought I'd list all of the relevant info in one thread.

(This assumes an annual mileage of less than 18,000 miles a year and is taken directly from the Nissan Maintenance booklet pages 18 and 19)

That scedules are at United Kingdom.
At 1 Year or 9,000 miles (whichever sooner) P1 service
At 2 years or 18,000 miles (whichever sooner P2 service (plus brake fluid change as extra item at additional cost)
At 3 years or 27,000 miles (whichever sooner) P1 service (plus coolant change as extra service item at additional cost)
At 4 years or 36,000 miles (whichever sooner) P3 service (plus brake fluid change as extra item at additional cost) - though P2 is exactly the same as a P3
At 5 years or 45,000 miles (whichever sooner) P1 service (plus plugs changed as extra service item at additional cost)
At 6 years or 54,000 miles (whichever sooner) P2 service (plus brake fluid change plus coolant change as extra service items at additional cost)
At 7 years or 63,000 miles (whichever sooner) P1 service
At 8 years or 72,000 miles (whichever sooner) P3 service (plus brake fluid change as extra service item at additional cost) see note above about P3 vs P2
At 9 years or 81,000 miles (whichever sooner) P1 service (plus coolant change at additional cost)
At 10 years or 90,000 miles (whichever sooner) P2 service (plus brake fluid change and airbag system inspection as extra items at additional cost)

As you can see, the brake fluid should be changed every two years (or 27,000 miles if sooner) (regardles of the service due at that time) and the coolant every three years (or every 36,000 miles if sooner). Plugs are changed at 5 years (or every 54,000 miles if sooner).

Hope that helps everyone and stops the repeated questions. Any comments welcome.

P1 (basic oil change and inspection); P2/P3 (oil change and air filter change and inspection). Apart from that nothing is really done on the 350z above an inspection (don't really know what we are paying for if truth be told).

I gues in USA it concerns the interval because it is for mineral oil however Infiniti dealer does not admit it. And in UK it is for full synthetic oil?

Lets be clear on oil changes. Assuming fairly normal use there is no reason whatsoever to change oil sooner that 5 to 7K miles. longer if you are using synthetic. This also assumes you are using a major brand of oil & filter and not some ultra cheap stuff. Changing more often than that is just throwing money away. Synthetic could easily go to 15K, but the filter won't so change at least that part more often.

I agree with you, it is I think suggestable to use bigger oil filter than standard oil filter for G35. For existance bigger oil filters would be Mobil M1-110 or Royal Purple 10-2876. Sure I use mayor oil brands. last oil I used was Eneos Sustina 5w30 ( When I drained old oil out as Eneos in 9100 miles it was pretty much of it like water, it was high time to change it) full synthetic and now I thought I give a try to ELF EVOLUTION FULL TECH MSX 5w30 (it has newest additives in API:SN). ELF of course is under Total ownership. I have never used some unknown names brands and always full synthetic. I our country 5L oil costs only ELF 33€=45USD. And oil filter Hengst 3€=4USD.
