a little while ago i changed my oil(which was mobil 1 fs), i barely put 3000 on the oil saw that it was pitch black, so i thought mobil must suck. So i changed to Eneos 5-30 and i just changed it with again after barely 3000 miles and the oil was pitch black again....is this normal? if not...wths wrong?! thanks fellas..

btw i use mitsubishi oil filters..

 

The oil will turn dark. Feel it to see if it's broken down (feels thin). When I change my oil at around 2.5-3k it's pretty dark. If the oil feels thin it's time to change it.

 

i have a buddy with a 360whp sti and he pushes it all day. he just changed his oil after 4000 and it was still see through....i dont push my car nearly as hard as he does and its black before 3000 ...yeah as sti is an sti but im kinda worried. should i be?

 

no you shouldnt worry iv always used mobile 1 and when i change it its always dark

 

I usually change my oil at 1500 miles, and its not pitch black, but still dark though.

 

I have always heard that if it isnt dark, change your oil brand because it isnt doing its job. It is dark in color, because it also cleans the engine.

 

yea, i freaked the first time i noticed it too hahaha

 

iv used royal purple on my dads car and i changed it out at 2000 miles and it was black real black but like stated above it doing its job and the detergents are working

 

Turbos make lots of heat, and heat is mean to oil

 

Not letting your car idle right after a beating will cook oil.

 

I don't ever pay attention to the color coming out. I am only worried about consistency and whether or not it is frothy.

 

Trying to discern the quality of the oil by color/feel is absurd. The only real way to tell is by doing a UOA.

 

You also live in vegas! its hot all day long.

 

Whadya mean?!? Ma pappy can tell jus by swish'n sum round his mouth. Den he gargles it to chek 4 dose guvernment chimicals.

 

If you change your oil every 3k miles with Mobil 1 Synthetic 10w30 and with a genuine Mitsu filter, and it's dark - thats a good thing. That means the oil is cleaning as well as lubricating.
