Probably just the phone operator reading off a script. Because doesn't Mobil also say, "Follow OEM recommendation"?
It wasn't a phone call, but an email exchange. And, I told them that my oil life monitor will let low mileage oil stay for 2 years. They came back and said that OLMs are notoriously inaccurate and that M1AP MUST be changed yearly, no matter what the OLM says.
So, according to GM, $12 worth of NAPA synthetic (on sale) would work for 2 (low engine use) years. According to ExxonMobil, $50 worth of M1AP could not be used for more than 1 year.
I was quite surprised that ExxonMobil wants me to change the oil more often than the manufacturer requires.
