Do you warm up the car every morning b4 driving?
 

I now wait till the rpm drops to about 1000 b4 driving. After I start driving, I try very hard to keep the rpm below 2500 until the water temperature is normal. Then I drive with WOT. Making this so complicated just to be gentle to my engine. I have a manual BTW.

Question is whether this is good or bad or simply does not matter? Some people start with 3000/4000 will warm up the cat quickly which is good to cat. I am quite confused. Any good theory out there?

i always wait until the rpm drops to about 1k before I drive.

I start it and let it run til it drops in RPMs after 30 seconds or so, then just take it easy for a couple minutes going out of the subdivision because there is no reason to drive hard or fast through there. I've always done it this way even in my truck i used to have. Just habit I guess

I'm with dbrandt01. That's what i've always done. The biggest thing for the motor is to let the oil get to operating temp that way it is at the viscosity that the engine was designed to perform at before driving it hard.

I wait till the rpms drop then I go. I keep things under 4000 rpm when the engine is not fully warmed up. Try to shift under 3500 mostly.

I usually wait for the idle to drop, then keep things under 3500 rpm until the water jacket gets up to its normal operating temp. It usually takes five or ten minutes for that to happen and for the transmission to start feeling warmed up.

I wish the car had an oil temp gauge.

I put on no gas until revs drop. That is very important so oil gets through the system. When temp needle is below cold, I give some constant 2k to 3k rpm until temp needle is actually pointing not 'negative' ie "off the charts" to the left. Without doing this, my brz will not shift into 2nd gear if it is cold outside.

No warm-up unless its below 0 Celsius, but I drive like a grandpa for the first 10+km no matter what to get all the fluids up to temp.

I don't let it warm up, but I don't drive it hard in the morning.

Also the car hardly ever sees anything below 50 degrees anyway.

What everyone else said, basically.

When cold, I don't necessarily wait to get the car moving. I believe some load on the engine, even when cold, is better for the engine because it increase the (oil) pressure. However, I keep it under 25 MPH and moderate RPM in any gear until several clicks up on the H-2-O temp indicator.



I do not have a problem with entering second gear as some do.

I usually don't warm up before moving as I am in a garage and exhaust is rather loud at 4:30AM in the morning for my neighbors, I try to scoot out quickly. (while keeping under 3k RPM)

I begin moving almost immediately, but drive gently below 3k until the needle is above C. Then drive normal under 4k until temp has stabilized. No redline or WOT until I've been driving 10-20 minutes depending on ambient temps.

0w20 full synthetic flows easily below freezing, but I believe idling/running at cold temps should be kept as short as possible. I want to get it warmed up as quickly as possible.
