Does auto engine shut off promote wear ? (1 Viewer)

i cant see how injection changes that, a cold engine will still need a richer mixture to start so injection will richen the mixture due to temp sensor data going to the ecu it may be tighter controlled but there will still be a wash effect

If the enrichment is tightly controlled there will be almost zero bore wash which isn't caused by cold-start enrichment as such but by an excess of fuel that isn't burned. Carb fed vehicles used exclusively for short journeys would contain oil that stank of petrol - especially those with a manual choke. It really is a non-issue nowadays.
