Die LTx-Motoren der C7 und C8 ohne LT6 gehören sicher nicht zu den am meisten LSPI-gefährdeten DI-Motoren, aber selbst GM scheint sich nicht sicher zu sein, dass es NUR mit Turbo-Aufladung auftritt.

ILSAC GF-6, API SP and GM dexos
Next-generation motor oils need to pass an LSPI test to meet these new demands. General Motors was first out of the gate and required oils to pass its own LSPI test. Its GM dexos1 Gen 2 specification took effect Aug. 31, 2017. GM dexos1 Gen 3 specification arrived in 2021 to further address the challenges that smaller, higher-powered engines present.
In 2022, GM launched a new dexos R motor oil specification covering 0W-40 and 5W-50 motor oils that can withstand the rigors of high-speed and high-load conditions created during high-performance driving. Currently, the specification only applies to high-performance engines used in Corvettes* and Camaros.*
These advanced engines with high power density, forced induction, multi-point fuel injection, cylinder deactivation and emissions systems are driving demand for more advanced lubricants. Modern high-performance vehicles push engine technologies to another level, requiring a motor oil that can protect components operating continuously under extreme heat and high-load conditions.
