Oil Change

however, I've been using ZMAX with my focus forever, and I must say, that after I add it, you start to notice that engine runs quiter and smoother too after about 7 days (you can tell it by how the steering wheel vibrates). Recently, I had my transmission flushed and gasket removed and replaced at 107000 miles. A mechanic actually came out and complemented me on the condition of my auto transmission saying that he is beyond impressed with how clean it was inside. He said that I must take care of my car very well and usually if people don't, he said american cars break, especially fords. My brother had a focus too, we actually bought two cars the same day, both focuses back in 02. His didn't run as smoothly as mine. So I do not think that zmax is bad and I'll continue using it and let you know if it causes any problems (at which point I'll be screwed, lol).

Ok, I have to pipe in here. Most cars are NOT investments. Unless, you are talking about collector cars. A car is a Depreciating Asset for you finance people.
I'm done.
I'm done.

P.S. The more you try to explain yourself, the more you will demonstrate you lack of knowledge on the subject.

If you use a longer change interval, you run a risk of Infiniti denying you warranty coverage on engine related problems.
Your car, your choice.

Manual calls for 7500 miles, except severe service, which includes the usual repeated short trips and dusty or salty roads. So most people do NOT fall under the 3750 mile severe service and will NOT run afoul of the warranty going to 7500 miles OCI with synthetic oil.

Lots of good info here and yet conflicting opinions on many things. And I love the **** match going on, which I find too funny. My question in light of all of this is simply to determine what the top 2-3 oil brands are when I go in for my first oil change? I'm at 4,000 km right now and believe I should be coming up for an oil change around 7500. I just basically need a quick grocery list of the top 1-2 brands I should buy. Thanks in advance.

"Generally, Schedule 2 (7,500 service intervals) applies only to highway driving in temperate conditions."
The "hook" for Schedule 1 (3,750 service intervals), in addition to the above 7,500 mile "generality", is "Stop-and-go traffic in hot weather or lowspeed driving for long distances". Per Nissan North America legal department, city traffic driving in summer constitutes stop-and- go traffic in hot weather, and urban freeway driving at 55 mph for 10 or miles can constitute lowspeed driving for long disances.
It's up to each individual owner whether, if they have some sort of engine related problem, they want to get into a warranty dispute with Infiniti (noting the booklet specifically says, generally, 7,500 mile change intervals applies only to highway driving in temperate conditions).

Normally, I agree with todd92, but, from the 2008 G37 Service and Maintenance booklet (page 7):
"Generally, Schedule 2 (7,500 service intervals) applies only to highway driving in temperate conditions."

Had you studied economics, you might have made a distinction between macro economics and micro economics. So again, sorry, but your home-made definition is not obvious to me.
P.S. The more you try to explain yourself, the more you will demonstrate you lack of knowledge on the subject.

If you take a few minutes to read my technical posts you'll see what Im educated in. You may be educated, but I can tell your have little knowledge of cars and even less of the engineering behind them.
