I recently changed my oil and had some questions about the dirty oil.
I use Shell Rotella 10W-30 diesel engine oil which is translucent and amber. It has been about 30 hours since the last oil change. The dirty oil is very black and opaque -- I can't even tell it is a synthetic oil.
I also think there's a faint smell of gasoline but I can't tell if it's coming from the dirty oil, the container it's in (it's a recycling container provided by the city and was not clean), or if I'm imaging things. Given the oil system flow schematic in the Moyer manual (5-3, figure 7), it doesn't look like there would be any interaction between the gasoline and oil but I've also read that Atomic 4 engines burn some oil so maybe I'm missing something and there is interaction between the two.
Is this normal, especially after 30 hours? If not, what are some diagnostic steps I should start looking into?
Should I be changing oil more frequently? The manual says every 50 hours but maybe certain conditions that my engine may be dealing with call for more frequent changes?
Is the color and opacity due to mechanical or chemical changes? Is the engine wear causing so much debris or is this due to reactions from heat, metals, etc, or something else entirely?
Thanks for any feedback or suggestions you can offer!
