How far are you running the OLM down? How many hours on the engine/OCI?
I've seen some complains of some brand new L5P's running down the OLM really fast, some people claiming it's going from 100-0% in 3k miles or less.
I bought a 2017 L5P (with 10,3xx miles) in December, it was showing 84% oil life when I bought it, now 2,200 miles later it's at 60%. It looks like I'm on track for a 7-8k OCI just like my dads LML tends to do. I do tow a fair amount and do daily short trips of about a mile, but the OLM algorithm doesn't seem to care. My dad does about the same commute that I do (plus a lot of idle time)and his truck still goes about 7,500 miles/500 hours per OCI.
I intend to run this fill down to 30% or so and let the dealer do my free oil change. From there I'll probably shoot for changing it with conventional 15w-40 around 20% oil life remaining.
How your fuel filter life looking?
My 2017 had 20% remaining when I bought it, now it's down to 3%. It looks like it will need to be changed (per the DIC) about every 10-12k miles.
