The oil-consumption test, and the arithmetic that decides itmajor
Report the loss and the dealer starts a consumption test: back every 1,000 miles, four times or more, level recorded each visit. A Palisade owner filmed his way through it and did the arithmetic out loud with the service advisor: "what's the service interval for Hyundai Palisade — 6,000 miles. How much oil does a Hyundai Palisade have — around six quarts. Okay, so if I go by the interval I'm going to be bringing you a car that's almost bone dry." That is the problem in one exchange. If a quart per 1,000 miles is treated as within range, the sump holds about six quarts, and the service interval is 6,000 miles, then a car sitting exactly on the acceptable line arrives at its next oil change empty. He asked for the threshold in writing and could not get it: "can you provide some sort of documentation that says that Hyundai allows this 1,000 mile quart of oil level? No, I've only heard it on the phone." The 2022 file shows the test being run and not resolving anything — one owner has had "combustion cleaning and consumption test" done "with no fix to the problem". An independent review of the engine family recommends changing oil at least every 5,000 miles and checking the dipstick between services, noting that owners of earlier engines in this family who did so "have surpassed 200,000 mi without major oil consumption issues". Run the test for the paper trail. Do not read a pass as a clean bill of health.
