I know everyone is really passionate about this but how about a reasoned discussion shall we.
I noticed my 2014 Mustang (5.0 with traditional Port EFI & 8 quart sump that averaged well over 20 mpg) called for a 10,000 mi oci by the IOLM.
A 2014 F150 3.5EB (GDI, Turbos, 6 qt sump and 16 mpg) also called for 10,000 mi oci by IOLM.
A 10,000 mi analysis on MC Blend from the Mustang was difficult to tell from the virgin sample.
A 6,000 mi sample of Mobil 1 from the EB looks like it's been shredded. Low-7's cSt in viscosity, near 10% fuel contamination and 6x the iron level and half the TBN of MC Blend in the 5.0 at 10,000 mi
Given these "challanges" is the consensus still to follow the oil life monitor? I will admit a 10,000 mi OCI on Synthetic on my newer F150 18 3.5EB would make me more nervous than a 20,000 mi OCI on conventional in my 14 5.0 Mustang.
What is the consensus on modern GDI Turbo engines with moderate oil capacity, modest mpg and a fairly aggressive IOLM program?
Follow the IOLM or change earlier?
