How many miles on it, and what are the driving patterns?

A picture of an oil stain on a towel is no way to determine whether or not to change your oil. Better to flip a coin. As edjack siad, mileage and usage pattern are the primary ways to determine if oil needs to be changed. Bottom line, when in doubt, change it up. It does no harm and can do a lot of good.

It just seems very brown, and I just bought the car.
Car was sitting for 2-3 months before I bought it.
I'll change the oil myself then, b.c it sounds like it's NOT life/death. ("Dude, change that oil NOWWWW!")
I'll order the filter and torque wrench and do it next week.
Thanks!

Which oil would you use from here for a NY winter?

I think I will get this for disposal purposes.

PS: It took my 5 mins. to post the pic.
It would take me at least 45 mins. to jack the car, drain, get the socket, etc.
Oh, and I also need to dispose of the oil... Another trip.

Get a 36 mm socket for the oil filter cap. No need to hog down on the cap; just snugly seat it in the bore. The O-ring does the sealing.

Use only German-made filters. Good kits come with the O-ring and pan plug seal.

Many on this forum like Mobil 1 0w40, but this topic is of a religious nature.

If you have no service records on the car, replace all its bodily fluids. Be ready for a cooling system overhaul.

Schedule a VANOS seal replacement.

oil does have a shelf life...

Id say no at this point but in the next few hours of run time yes..

at least that way you have a reference to when it was last done

All oil is brown. It's supposed to be brown.

Showing a picture of brown oil on a towel is like showing a picture of red blood on a bandage. It doesn't tell us (or you) anything.

Note: There 'are' some who say you can pinch your index finger and thumb on the oil on the dipstick to check its latent viscosity; but I'm not one of them. As already mentioned, there are places you mail your oil to who provide a complete analysis.

I'll order the filter and torque wrench and do it next week.
Most people don't use a torque wrench - but some do ... and ... others use it to twist the drain bolt in half (ask me how I know).

Any good quality oil you want.

Do a search for 'what oil' to see how many thousands upon thousands of times that question has been asked.

Here is just one (of very many) approaches for answering that question:

Can someone tell me if my cholesterol is too high?


Sorry...I couldn't resist, Bluebee...your analogy made me laugh out loud and I couldn't get the thought of a bloody bandage out of my head. :rofl::p:rofl:
