I was hoping you guys can help me on my situation. I have a 2014 SXL 2.0 and have 30k miles on the car. I did an oil change at 4,818mi. Was running Amsoil SS 5w-30. I sent the sample off to 2 different analyzers. I have used Blackstone for all of my tests and love their service. This time I wanted to see what oil analyzers test showed. This is very first test on this used car I purchased.
The issue is that 1 test showed .5% fuel and the other showed >5.0%. Huge difference!!.
Both did report 8.7 for viscosity @100C. So the oil is diluted and below the 5w-30 range. All wear metals are very good and no other issue were found. I couldn't smell gas in the oil but ir seemed a little on the thin side so when I changed it I went with 5w-40. Happy I did!
So the question is, which test do I believe and do you think there is a fuel issue with my car? And why are the test results so different?
