Diesel in a gas engine is generally worse. Gas engines can't combust diesel, leading to severe engine damage, clogging fuel injectors, and often requiring a costly flush-out. Meanwhile, a small amount of gas in a diesel engine can lower lubrication but might still run, causing less immediate damage. In either case, seek professional assistance immediately to avoid long-term engine issues.
