I changed the oil in my 2020 3.0l duramax with AC Delco DexosD 0w-20 Light Duty Diesel Engine Oil 7 qts with filter at 27,000 miles. At 30,000 the truck went into limp mode on hard acceleration and the check engine light came on. I shut off the engine, waited 10 minutes and drove it . The light was off and the engine ran fine. I did another hard acceleration and it went into limp mode. I took it to the dealer where I purchased it and after 2 wks of speculation regarding wiring harnesses and oil pan sensors they determined that I was 4 qts of oil low. Sooo...it was either burned or leaked. Does anyone believe this? Wouldn't the diagnostics have showed low oil? Where did the oil go. I still have the empties to prove I put in seven quarts. The oil and the filter came as a kit from amazon. Anyone have any ideas?
