Probably the only issue on the list that the car owner can actually do something about, is dry start (little or no oil still left on the parts until the oil pump finally gets oil to the parts) While probably not a solution for everybody, there are kits available with which you can pre-oil your engine before a cold start. This kit consists of a mount, an electric oil pump to be installed externally, and several feet of hose plus the various switches and relays required to operate it all. A pre-oiler is plumbed into the engine's oil system, (usually via the oil filter mounting). Once it's installed, you then simply press a button under the dash. The electric pump then circulates oil through the system under pressure to your rings and bearings et. al., with the touch of a button.
So is it safe to say that the air-fuel mixture is rich during cold starts not because the engine is trying to get up to temperature, but rather because of increased engine friction?
During a cold start we will have poor fuel atomization and vaporization, some of the fuel particles adhere to the walls and manifold passages of the cold engine, and hence, the fuel is intentionally made rich. The increased friction is mentioned in this video because the intent of the video was to advise drivers to give due attention to the warmup phase, improper warmup or revving a cold started engine could lead to accelerated wear! The increased friction during cold start causes accelerated wear. But the opposition caused due to friction is negligible in comparison to the massive power generated in the cylinders, and no worry is there to increase the mixture ratio in consideration of the friction value.
What a joke video!...every manufacturer provides recommended climate condition info...just read the owners manual recommended procedures! All you had to say in 60 seconds.

great thumbnail, didnt realize you were a small channel
It's very good to have here on our channel!

Thank you very much indeed! Well said. Thank you for sharing. Pleasure having you on our channel!
Well done. Keep it up!!
Thank you! Will do!
Good job.
Many many thanks!

Indeed!
