I just went to my dealership yesterday to get my first oil change. I had roughly 2700 miles on it. The person did not recommend me getting the oil changed untill 3750 miles like the manufacture recommended. She said something along the lines of letting the oil soak the engine or something.

Almost everyone here says to get the first oil changed after ~1000 miles but the service department lady says to wait till 3750. Who to trust?

 

I have had four new cars and with all of them I do what the manufacture recommends… So for the G37 I’m going to change the oil at 3750.

 

We all are self prescribed mechanics. you didn't get your license and degree online yet?? shame on you. LOL, do what you feel is the best. If you want to listen to us by all means do it. If not listen to her. Call a few more dealerships, see what they say.

 

Letting the oil soak? lol, wtf is that?

 

Yea the dealer told me to wait also.

 

I'm at just over 2K miles now after a bit over of month. I plan to wait until close to 3750. But what do I know? Well, that's the point. I really don't. So I'm going to go by the manufacturer's recommendation.

 

^^ She said "we don't want to soak you, so maybe you should wait"
Ok, that was a joke and no disrespect meant to any dealers on here!!!

 

I dont understand people at all. I have had my own shop for three years and have been working on motors my whole life but i still dont claim to know more then the people who design the car. Stick to what the book says. they have those standards set for a reason. No matter how smart you are you dont know more then the enginiers...

 

Thats strange because some car manufactures recommend for you to come in right after 1500 to check for scraps in the oil filter.

 

Ah but see the key word in your statment is some. No two engines are a like. Nor are different car compaines engine's alike. everyone builds their motors to different specifications. Which is why every company has different requirments for break in and when to change oil and so forth. And the purpose of changing the oil is not to get the "scraps" out of the oil filter. Its to get the metal shavings out of the oil pan which is where majority of metal shavings will go which is why all racing teams run magnetic drain plugs in the oil pan, transmission, and diff housing. Many compainies like spoon, mugen, asm and many more produce after market plugs that have built in magnets for those items.

 

If you change your oil before 3750 miles, your engine will blow up into a thousand pieces!

In all seriousness though, if you change your oil before 3750, nothing bad will happen. It's probably better that you do, because you'll get all those tiny metal particles out of your engine

 

Plus the 3750 is a MAX wait time, not a minimum. Personally, I'm reluctant to have it changed @ 1725 miles as I am afraid of the risk of the dealer forgetting to tighten the filter or oil pan plug or scratching the heck out of the black paint when they wash it accidently after being told not to.

 

no 3750 is the early oil change if you read the book the max or normal one is like 7k and change. If you change your oil before the time recommended one thing will happen for sure and another can happen. One you will for sure be wasting your money. They set 3750 for the early first change for a reason. because the enginers determind after hundreds of thousands of miles of testing on this motor that is the ideal time for the oil to be changed. The other problem is a motor that is fresh or new is in what is called a memory stage. Its basically learning itself. Meaning the seals are learning to set in the right postion, the piston walls are breaking themselves in. And when you remove the orignal oil too soon the motor looses that memory. It can cause the seals to not set correctly causeing blow back of oil. I have seen this happen to many cars. I have had a lot of S2000's, Evo's, Sti's, G35's, 350's etc come into my shop and the owners want to know why their car is burning so much oil and they are seeing blue smoke. The first thing I ask is how they have been driving their brand new cars. 9 out of 10 times they say i have been driving it hard from day one. Once we remove the head and start inspecting things low and behold the seals are blown and oil is leaking into places its not suppose to be. Another person falls pray to thinking they know more about breaking in a car then the people who designed them....

 

So how much experience do you have with the new G37 engine? Seems like you know everything about it.

 

I don't see him claiming to be a G37 expert. His post is clearly speaking of good related experience and in general terms. Are YOU a G37 engineer?
