When i brought my car in for its first oil change at the dealer my car had around 3k miles and i brought in my own oil. I used Amsoil 30 weight. 3k miles later i check my oil and i noticed it to be slightly darker so i decided to just change it anyways.

Doing the oil change myself when i unscrewed the oil drain plug, the oil came out very very dark, almost black. I was quite shocked because from my previous car, being almost good about changing it @ around 3k miles, the oil never came out as dark as what i saw.

Now is/was this normal for some of you guys who had changed your own oil? Is there any test that i could use that i can id the old oil being a certain brand? Or knowing if it was syn or dino oil?

I mean this just got me thinking...

Either this is sort of normal and my dealer did change my oil or this is not normal and the mechanic from the dealer gave me the shaft.

Advice please.

 

Maybe the dealer didn't change the oil afterall? Shockingly this happens with dealers now and than.

Just change your own oil from now on to make sure the job is done right. And then compare.

 

humm thanks gsrthomas

 

Oil color has nothing to do with how dirty an oil is, nor how well it lubricates. http://motor-oil-engineers.com/oilcolor.htm and http://www.searchforparts.com/import...tamination.php

If you are concerned about the condition of the oil you drained from your engine, send a sample of it for an oil analysis. Many people here use Blackstone Labs: http://www.blackstone-labs.com/

 

Awesome, thank you for the info. Now i know what to do.

 

Next time mark your oil filter so then u can see if they changed it.

 

Won't work. The IS has a cannister type filter; they don't replace it, they just change the paper element inside.

 

Ah, you beat me to the punch. Yes, the Gen 2 is a cannister filter like the beemers. You can put a little hidden tourque seal around the lip that is unoticeable to the dealer. hen chek and see if they disturbed this seal when removing the cannister filter plate.

 

When you pick your car up check the dipstick it should be very light as compared to when you bring the car in for the oil change. If you are used to checking the dipstick you can tell fresh oil from used by sight the fresh oil will look almost like a transparent golden color.

 

True, but unless you're an investigative journalist doing research for a dealer rip-off story, I don't see the point. For the amount of effort involved: putting the car on ramps, removing the three bolts to remove the plastic filter hatch, putting the goop on the lip, then replacing the hatch and three bolts, and finally doing the whole thing again after the oil change to see if your mark is still there... It would take significantly less effort to just change the oil yourself.

 

There will not be a next time for the dealer. If i want things done right i have to do it myself.

 

Haha no, goto Servco for ONLY the free check and w/e tsib you want THEN either do it yourself or goto LXS

 

Oh yeah LXS ppl are the bomb i almost forgot about them. I think when Mazzuri starts selling their headers, im planning to bring it there for install.

 

Yep, whatever Revision cant do then its LXS for me
