I (and you should, IMO :tease) treat the DIC as a suggestion as to where the extreme level is. It’s a good thing they added, as it varies with your usage, It gives the owner a base point to work from, depending on their use and abuse.08 GMC, LMM. how reliable is the "% of oil life remaining" screen shown on the DIC? I am nearing my second oil change and the mileage on my truck is far less than the first oil change. Hope this makes sense.
So, got a new truck and after driving it for about 2,800 miles, oil life DIC was saying to have it serviced. Went in to the dealer, they couldn't figure out why that was occurring, they changed oil and reset DIC back to 100% oil life. After going another 1,700 miles, oil life showed 44% left before changing it again. Doesn't make any sense! I do get the idea of every 5,000 and based on use, driving, towing, hauling, etc... but I barely do any of any of these things, just normal driving, so curious as to if anyone had nay feedback, similar experience or any ideas what's happening... Thanks!
Hindsight is 20/20 and it aligns with DRC's advice.Unless you feel you have engine issues don't waist your money on analysis put it towards servicing.
extended OCIs means less downtime = savings.Big companies do oil analysis on big rig engines, but they have much larger oil filters and a much larger oil capacity and usually can go more miles, checking at least once in between changes.
