Oil blotter test - cheap

My SUV has nearly 140,000 miles and I'm not seeing any issues. But I'm interested in testing now and then for gasoline or coolant in my motor oil in part to be proactive but also to possibly modify the oil change interval due to the impact of dilution on viscosity.

Getting a mail-in test is too expensive for me as I'd like to do the test periodically. Is there an inexpensive DIY oil blotter spot test I can buy or make myself?

I've always sent in my oil for analysis. Then you get back the report that covers a lot more than just coolant leaks. They tell you what metals they find in the oil which can give you an idea to what's wearing inside the engine like bearing journals or the crank...

I accept that sending a sample is preferable and I can see doing so if I have reason to believe I have an issue, perhaps after a compression test. In my situation, though, spending $25 or so periodically seems to be expensive if my concern is basically mileage. I'm hopeful there's a way to test in a topline way at a low cost.

Is there another way to determine if my oil is diluted?

Year/make/model of your vehicle.
How often do you change your oil?
If there is no coolant loss I would expect that there is no coolant in the oil

I think to answer your question "Is there an inexpensive DIY oil blotter spot test I can buy or make myself?" the answer would be "No" - not a test that you could trust or rely on.

For $25 , instead of testing oil, you could change it more often ...

would probably just check the oil level more frequently if your level actually increases probably may have an issue but most problems that would add a significant amount of fuel or coolant to the oil would usually cause other issues.
