I have A 13 equinox with the 2.4. 113k miles. I want to get a uoa at 3k on a oci. I mainly want to see fuel dilution. Im not sure if my high pressure fuel pump is going. Been reading on the nox forums that symtoms are high oil usage and fuel smell in oil and cold start misses. I have all of those. What uoa do u rec i use? I thought i heard someone on here say napa did them. I have a local napa. Who do you guys suggest i use for a uoa mainly for fuel dilution?
