Dark engine oil

**Zhandros** · May 4th, 2011 04:48 PM

Can you guys give me advice..

Some 3,500 kms after an oil change, the oil on my 3.2 strada is quite dark brown already. But the oil of our diesel innova with a similar mileage after an oil change is still light to medium brown. Both use the same oil (15W-40 Castrol GTX Turbo Diesel)

Is this a cause for concern?

The oil getting dark on a diesel is normal, heck after driving it home from a fresh oil change in the casa it could already be black. What I'd like to know is how long the oil should stay in the engine (actual kms driven vs actual running time). Does anyone know if Caterpillar still does EOA's?

Oil getting dark is normal as this means it is absorbing the dirt of your engine. IMO, its even more of a cause for concern if it doesn't get dark as you'll wonder where the dirt goes. the rate at which it changes color will also differ between engines/brands.

* TS: Try mo sir yung Shell HX7 Diesel next time. Mine has 1,000kms on it and not yet dark colored compared to using multi-grade oils. Just a suggestion. Mas malaki rin kasi at mas malakas engine ng 3.2 TDic CRDi vs 2.5 Turbo CRDi kaya malamang mas maraming soot and carbon deposits IMO.

You might want to try a quality oil filter like Baldwin or Fleetguard that have much better filtration and higher dirt holding capcity over OEM. I would also add a oil catch can.

Thanks for the responses.

This thread pretty much has it covered. I don't know your OEM number so I can't tell you what filter it is. But if you get it then I can tell you.

Actually, I'd be more concerned about the diesel Innova here.... Engine oil getting dark in a diesel engine means that it is doing its job of floating the deposits in your engine.....

Any comment from the diesel Innova owners?
