Help Is this water in my Oil?

Five hundred miles since my last Oil change. Pennzoil 15W40. I'm worrying that I may have a head gasket problem. When I switch the car off and check the oil it looks really bad. Kind of diluted and all over the place. I've tried attaching some pic's to show what I mean. Apologies for the poor quality. The first two are what both sides of the dipstick look like immediately after I shut the engine of and pull the stick.




The second two show what it looks like after I wipe the stick and check it again just a few seconds later.





I've not really noticed this difference before but since I've started doing my own oil changes I'm becoming anal about this stuff. Car's an 81 240D with 380K miles and 210K since the engine rebuild.

- Peter.

No. Water in the oil will be a brown foamy mixture.

I don't see anything like the frothy milkshake expected when oil and coolant get together in a big way. Keep an eye on the coolant level and look for an oily film in the coolant reservoir.

It looks pretty normal to me, also. It is normal for the oil to read high on the dipstick before you wipe it after the engine has been running.

I've been running 15w40 Delo in mine and get the same look to the stick, looks fine to me, as others said, water in oil is VERY distinct, it will be foamy, or pudding like, and have the brownish color of chocolate milk. When I was still driving truck, the guy handed me a Freightliner with an engine "he and his brother just rebuilt", ran great, but the oil was about like coffee with too much creamer after the first trip, told him about it and he denied it saying it was just condensate and was normal, next time got worse, mentioned again and brushed off again, third time never finished trip, he tore engine down and found boiled off bearing babbitt and an oil cooler with a leak into the coolant passages......can we say expensive lesson? lol

My dad had a Honda outboard motor on his boat that cracked the block after being rebuilt from being seized due to lack of oil at 5500RPM . Long story short it was a Honda design flaw (noted in a service bulletin/recall that Honda didn't inform us about) that resulted in corrosion of the oil pan, which would eventually form a hole, draining all the oil.

Back to the subject, when the oil got through the crack into the cooling water, the unmistakable sight of vanilla milkshake started shooting out of the cooling water return. The engine pretty much died shortly thereafter.

Many letters to Honda threatening legal action got us a new powerhead on their dime.

My point is, water mixed with oil looks like a vanilla milkshake, and that oil on your dipstick doesn't look like a vanilla milkshake I'd be drinking any time soon
