: Anybody else seen a dramatic reduction in the OLM life after the reprograming?

I find that I am lucky to get more than 50km(30) for each % of oil life. Some time It will drop 2-3 percent in one day with only 10 - 15 km(6 - 9 miles) covered. That is with weather above freezing. Dealer gave me some Bull$hit excuse that my engine is getting older(75,000km/45,000miles) and needs more frequent changes. Even my old Roadmaster(500,000km/300,000miles) using nonsynthetic gets a longer OLM interval. I am going to be voting with my wallet later this year when I get rid of this thing

It is supposed to shorten the interval, that's the point.

Longer intervals allowed more time for it to burn low enough to damage the timing chain. Since no one checks their oil anymore GM decided to implement a band aid by simply shortening the OLM interval so less oil burned in between changes.

It's a fix....kind of. More frequent changes led to less vehicles with bad chains since the oil level didn't reach a critical point. Also meant more money for their quick lube bays....

Just ignore it and change your oil based on mileage or when you want to!

What's the reprogramming you're referring to?

A recalibration of the OLM for certain model years equipped with the 3.6L....it just shortened the oil change interval. Don't remember what years exactly.
