Highly recommend you do some reading
The relationship between fuel dilution of the crankcase oil and low-speed pre-ignition (LSPI) was studied experimentally with a highly-boosted 1.8L turbocharged gasoline direct injection (TGDI) engine fueled with RON93 gasoline. It was found that properties of oil particles entered the engine cylind

All you have to do is get the flashpoint low enough for self ignition. Regardless of engine, this can happen. Basic physics.
Heck, this has been discussed on BITOG before...
Great YT video "3 Big Problems With Direct Injection Engines (Gasoline)" How Gasoline Direct Injection causes Chain Wear, Fuel Dilution, and Low Speed Pre-ignition (LSPI) Recommendation to use API SP or ILSAC GF-6A rated oils for modern engines. What do you guys think about using this...
