Oil wear ?

[J_SULLIVAN]

Between now and the last oil change has been around 500 miles. I did this the last oil change and here's what it is and what is happening. I use Cast. syntec 10w30 and a NAPA filter. 697 is all stock and for the very most part I do NOT drive it hard out of fear for its life. The problem is when I get about 100 to 250 miles on the new oil it looks like I've put about 10K on it! Its just turns BLACK! Not only is it just black its lube feel is very thin as if to say the oil has lost its purpose already... WTF??? :-?

What does it smell like?, gas maybe? My oil looked like poopoo after I found that my injectors leaked a little fuel into the cylinders when sitting.

No smell other than oil. No bubbles or white foam so no moisture getting in either. Your not around it so no Budweiser getting in it too! :lol:

This is normal. In fact, if the oil does not change color during use, it is not doing its job. Good engine oil will contain detergent additives that help clean up the engine and in the process cause the oil to turn black. During an oil change, the contaminants picked up by the oil are removed from the engine. If the oil does not turn black after some time, it could be there are no detergent additives present, and that all the soot and deposits are still clinging on to engine parts. Hence, in such a situation an oil change would bring out relatively clean oil but the residuals are still stuck with the engine.

Don't worry about it :wink:

Ive used castrol dino oil for eons and it seems to turn color pretty quick. Sounds normal IMO.

The oil should be black. Otherwise it's not doing its job
If you want to make the car "cleaner" rinse it a few times with cheaper oil 1-2 times. And then put your normal oil in it. Just make sure you use synthetic to rince it with if your using synthetic. And vice versa.

Just wondering because everytime I get my oil changed in my other 2 trucks the oil isn't jet black and it sure doesn't turn black after only a few hundred miles but what do I know...? :wink:

Turbocharged cars isn't the same thing. The oil is lubing the engine + a turbocharger and is also alot more hot than in a normal truck / car. The Turbo generates lots of heat.. Atleast the last time I accidentaly put my hand on it
