What you are seeing is moisture mixing with your oil and clinging to surfaces that you can see like oil cap and often times a dip stick. This is very common in the winter especially in the extreme cold. This also is very common on vehicles built from the late 60's to the mid 80's. If the problem gets worse and you start seeing clumps of the milky oil on your dipstick you might want to have a mechanic check it out for you. But for now I would just change the oil and the filter and keep an eye on your oil level. If the oil level should increase between oil changes you have a problem that should be corrected soon. I might add that my 76 Maverick Stallion has done this since it was new. Also just for your info this is quite common in the GM 2.3 quad four motors.
: I found a creamy light brown deposit under my oil cap. Any ideas what this is?
