OIL CHANGE PROBLEMS:ENGINE RUNNING ROUGH

[DRO@G37]

Hey everyone. So last week i took my 09 g37 sedan for its first oil change at 3,700 miles. After i left the dealer, i noticed it wasnt running right, i just figured it had to get used to my driving again after service. Yes terday, i noticed they didnt change the sticker on windshield, it still said oil change due at 3,700 miles, so i did some inspecting, and checked the color of the oil, which is a dark brown. (also, my RPMs at idal is rough). I think they forgot to change my oil , but the dealer swears theres no way...What do you guys think? Is it possible for the oil color to turn dark brown in only 400 miles? ....Ps. this is from Metro infiniti of monrovia, ca

No. With 4100 miles on the car, unless you are red-lining it all day long, the oil shouldn't be dark.

well the test is to compare to the old oil.Yes in 400 miles the oil will darken a bit but shouldn't be that deep black color. After 3700 miles the oil was most likely a deep black color. So if the oil you see on the dipstick now still looks clear and brown then it's probably new.

But there's no explanation for the rough idling. An oil change is an oil change is an oil change. Unless they did some ECU update or knocked a sensor loose then I can't see why an oil change would cause rough idling. Idle RPM and tempo is electronically controlled.

That's why I NEVER take my car to the dealer unless it's free. Dealers have the worst service record and knowledge in my opinion and experience.

This oil changed was comp on the dealer because of my purchase agreement. Thats why i think they didnt change the oil. ILL NEVER again take my Poor poor G to the dealer. ... I have an appointment tomorrow with my service adviser to check the problem out. But from my experience with infinity (only about 2 months), their techs are careless, and the service advisers ill informed

Did you use ester oil?

If you didn't buy ester oil you might notice this please see the sticky. Some of the people at the dealers are total idiots. Noob.

So did you decide to buy ester to correct the idle change?

I agree fully. I don't think that service techs at dealers really care. They're not any more knoledgeable than any other mechanics. People are often mesmerized with the process of "dealer specific service." In my opinion, they're nothing special.

That's kind of a d!ck assumption. Although some of my colleagues are only in it for the money that is true for all occupations. I can guarantee if you get to know the person that is actually working on your car things should go smoother if everyone is on the same page. You don't need to bribe them, just show them what you are talking about. I personally think the biggest problem is communication.

One other thing some of you guys tend to forget that is if the dealer messes something up they will fix it. If the guy you know or you screw something up it's usually going to end up effecting your credit card balance.

However, I have enough pride in and take the care and time to ensure my car gets what it needs; a nameless service tech doesn't have that same sense of pride or ownership. As a result I've never (knock on wood) created further problems that needed to be rectified because of my own carelessness or lack of knowledge. To the contrary, the half dozen or so times my cars have gone to dealers for service there as been a problem, without fail. Not once have I picked up my vehicle from a dealer when everything has gone as expected. This includes 3 different vehicles at 3 different dealerships.

Here's one perfect example: When I first got my '05 Mustang GT I probably washed and waxed it every other weekend. The interior of that car still had the new car smell for 3 years or so. The very first time I brought it to the Ford dealer for my free oil change, they got grease all over my seats and steering wheel and forgot to tighten the filter enough so it was dripping oil. Luckily, because I'm such an anal bastard I saw it dripping before it lost enough oil to cause a problem. I brought it back to the dealer and they cleaned my interior as well as the undercarriage of oil. One 15 minute oil change resulted in 1 additional trip to the dealer and probably 4-5 total hours of my time.

The other 8 or so oil changes I did myself on that car never once resulted in a speck of grease anywhere inside the car nor did I have any mechanical issues because of it.

my dealer experience has been great in infiniti's defense

But I agree, I go in there knowing whats needed to be done to my car...

So i talked to my service tech. We went on a test drive in my car, and he was kINDA INFORMED.....although for the entire test drive he tried to convince me that my car is supposed to run and feel the way it is(rough idle)....Okay Mr. Tech, i come to find out, its NOT! Its supposed to run smooth, on syn ethic oil..But he did get rid of a a little buzz coming from the dash ....I agree with WHEEL4, i've always been the same way, wax, wash, repeat. The first time i took my G37 to dealer, about 1 week after i bought it, i found blk smug on my white leather! on my door, and carpet.....Ummmm..Yea real professional
