General Motors’ new Generation VI small-block V8 will bring a notable change to the 2027 Chevrolet Silverado 1500 and GMC Sierra 1500: the 5.7-liter L76 and 6.6-liter L78 engines are expected to replace the traditional oil dipstick with a digital oil-level readout integrated into the redesigned infotainment system.
New GM V8 Moves Oil Checks to the Screen
Originally reported by The Verge, the new electronic interface will provide maintenance and vehicle-status information through the 16.3-inch center display. Among its features will be a virtual dipstick that replaces the traditional crankcase-mounted tool on all Gen-VI small-block V8 engines.
Checking the oil level will require navigating the infotainment system rather than opening the hood and inspecting a physical dipstick. The change could make routine oil checks more convenient from inside the truck, particularly when checking the level in difficult weather conditions.
However, owners who prefer to verify the oil level themselves may find the digital system less reassuring. That could be particularly relevant for returning owners who have been affected by reportedly unresolved recalls involving the 6.2-liter V8 used in the current-generation Silverado and Sierra.
The digital system could also be less convenient during an oil change. Instead of checking a physical dipstick, owners would need to use the infotainment system, potentially handling the touchscreen with greasy clothing or oil-stained hands.
Why GM Is Removing the Dipstick
The 2027 Silverado 1500 and Sierra 1500 feature an all-new infotainment system whose design and programming required investment from General Motors. The outgoing Chevrolet and GMC full-size trucks, along with most modern trucks, already use an oil-level sensor integrated into the onboard computer.
Because the sensor is already part of the vehicle’s electronics, turning its information into a maintenance display on the infotainment system likely did not require additional physical hardware costs, according to the article.
Removing the traditional dipstick could also reduce parts costs. General Motors sold nearly 600,000 light-duty Silverado and Sierra trucks last year, and eliminating a 50-cent dipstick from every truck would amount to $300,000 in parts savings.
GM’s New Generation VI Small-Block V8
The digital oil-level system is part of a broader set of changes coming with General Motors’ Generation VI small-block V8. The engines are set to appear in the 2027 Chevrolet Silverado 1500 and its GMC Sierra 1500 counterpart.
The 5.7-liter L76 and 6.6-liter L78 will rely on the electronic oil-level readout rather than a traditional dipstick, making the infotainment display a more central part of routine maintenance information.
The potential parts savings from removing the dipstick are relatively small compared with the $900 million GM spent developing its sixth-generation V8, but the change reflects another move toward digital vehicle systems.
