WHITEG20

Hello,

The oil, after a 3 month, 2500 mile oil change was quite dirty. A dark reddish brown color. I was wondering if this is normal.
Also, I remember that my engine used to have a "sweet" aroma to it.
Recently it seems to have faded(after 3.5 years). I wonder if the 2 things are related.
My G20's engine idles at normal rpm of 700 and is very smooth and quiet.
However, I might switch to synthetic oil from next oil change.
Thank you .

What oil have you been using? How many miles on the motor? Do you always change your oil @ 3-month or 3k?
