Oil sludge 7K after the last oil change

By Tyson's Corner Center mall?
You could drop some coin in that joint while waiting on an oil change!

 

Yeah, but now I’m doing oil change at home ...

 

Good call on the future oil changes. Even dealerships that care, won't care as much as you do.

And Tyson's Corner was mostly in Jest. I can barely afford to walk in the place.
My little sister buys her fountain pens at Levenger's @ Tyson's. If I didn't walk in with her, I'd be getting looked at for shoplifting. lol.

 

They won’t even respond to my inquiry, don’t expect they would do anything about the documentation.

 

Why should they. They never changed your oil or filter. Don't expect them to admit it. Sludge like you experienced is way beyond normal/

 

I change mine every 5,000 miles and engine has always been smooth. I wouldn't wait until 10,000 as a oil change is pretty cheap compared to a new motor.

 

Update about the brown clumps in the oil filter cap: took some out with a screw driver this afternoon. They are black and sticky clumps of oil. After the oil change the new Mobil 1 oil on the dipstick looks very clean now.

 

I would say you are OK now. Just don't trust slimy dealerships to do anything. Learned that myself with sloppy work on our Jeep JK. Never again!

 

Knowing now that the OP is in the greater DC area, he's probably the one in a thousand in that demographic that would have ever noticed their oil wasn't being changed.

 

Here's my dipstick with just over 19,000 miles on the engine. Oil change at 10,125 miles (or so) by the dealer.

I'm actually pretty impressed with how clean this oil looks. It's not black.

 

I suspect that something else was introduced to the oil.

 

Maybe the dealer put something heavier than 0W-20 in.

 

I'm thinking something a little more grittier. Dealer? It's possible but I suspect someone else did it. Not saying it's the OP.

 

This thread got derailed a bit. I'm glad the OP got a fresh filter. It wouldn't be a bad idea to do another change relatively soon to make sure most of the sludge is out.

To those who think changing oil is stupid I can offer no advice. It's your money; make your choices.

To those who believe oil change intervals have been extended by the manufacturers as a sop to environmentalists you are partially correct. Obviously changing your oil every week would be an foolish waste of money. But to those of you laughing at people who change it 2-3 times a year instead of once: My question to you is do you think an extra $60 a year to extend the longevity of your engine isn't worth it? Even if you do, why go on an evangelical crusade to talk others out of it?

Sure 3,000 miles is probably too often and Jiffy lube proglumated that to increase their revenue. But 10,000 is at the other extreme especially if your driving conditions aren't all long highway miles.

 

Smh ....

 

And yet we'll never know if engines live a shorter life due to following the manual on oil changes vs changing it twice as often.

 

I believe the oil change interval is shorter of you meet certain hard wear criterion. Its in the manual.

 

So for those don't believe the manual, that would mean changing as often as 2,500 miles then right?

 

Unfortunately not. All most of us will ever have is a statistically insignificant sample size of one.

I just don't understand the argument for extended intervals. If oil changes were expensive it might be worth rolling the dice. But they are just about the cheapest maintenance you can do aside from rotating tires.
