I have read and seen many articles regarding car warm-up time from a cold start in the morning. Each article varies, some say I can wait about 10 seconds, some say 1 minute, others 3-5 minutes... So which seems to be the most optimum.

My car cold starts at 1500RPM, and then goes to 1000RPM in about 1 minute. My car uses 5w-30, instead of the recommended 5w-20.

Any ideas?

 

you should use the oil recomended for the car. i remote start mine for maybe 2 mins before i leave the house. i dont need the car warm, just the engine to get the oil flowing around is okay. as i drive it warms up faster anyways.

 

When I was in high school driving a '77 Camaro, I let it warm up about 5 minutes if it were freezing outside. But with how far the technology in fuel injection and engine construction has advanced, the days of letting your car warm up in order to assure it operates correctly or causes minimal wear when driving are over. For newer cars, once you start it up it takes a few seconds to get oil where it needs to be and at that point, you're good to go. It's probably a good idea to avoid high RPMs for the first few minutes of driving just for good measure. The oil's thicker when cold and doesn't flow as well. Reving the engine while cold is probably pretty hard on the oil pump as well. But letting your car warm up for any reason than to make sure the heater is warm when you get into the car is just wasting your time. Assuming the car is post 1992 or so, it's going to run about the same (assuming it's in good mechanical condition) and incur the same amount of wear regardless of a 5 second or 10 minute warm up.

 

Exactly and now they are coming out with new technology that allow the car to warm up even faster.
Funny how people start reving the engine to warm up the car faster LOL
