This is my first UOA for this particular vehicle. As the title states, this is German Castrol Syntec (Gold) 0w-30 in a 2008 Infiniti G35 VQ35HR. No makeup oil was used in this UOA. Here's some more info:
Time on oil: ~4 months
Miles on engine: ~36k
Miles on oil: 8,100
Air Filters: OEM original (just changed both with Napa Gold filters)
Oil Filter: Napa Gold - FIL1356 (slightly over sized compared to stock)
Temps seen during operation: mostly 40 deg F - 80 deg F
Driving Pattern: Conservative - 90% Hwy/10% City
Driving frequency: Driven every day (with a few exceptions)
Average trip duration: mostly 60 minute drives
Time spent in traffic: between low and medium on average
The car has had a total of 7 oil changes so far: the first 5 were done before the 20,000 mile mark with Castrol GTX 5w-30 and the last 2 were done with GC 0w-30.
Shell V-Power 93 octane is the only fuel used in this car.
Since I put a pretty decent amount of miles on this car, I would have liked to keep the OCIs around 8k miles, or so. Should I just play it safe and stick with ~7,500 mile intervals though?
Thanks in advance!
