Is the OLM in the 2011 Chevy Malibu LT calibrated for a specific type of oil, such as a synthetic blend or full synthetic oil? I have put full synthetic in it and my understanding was that the oil lift should last a little longer, around 7,500 miles, but my OLM is reading low and it has been less than 5,000 miles. I drive mostly on the freeway, but it has been a cold winter, which I understand can shorten the lifespan of the oil.
My car has 79000 miles.
My car has an automatic transmission.
