No. The only people who wait are ones who don't understand the proper way to warm up a car.
Just wait the ten seconds that the owner's manual says. If it's really cold, you might want to wait until it comes off the initial high idle. But the best way to warm a car is to drive gently, keeping the revs down until warm.

You don't have to wait 5 mins before you drive the car LOL. Just keeps the revs low (I keep them under 3k) until the engine reaches optimal temprature. Then you are good to go. You only have to wait for the engine to get warm before you turn OFF the car.

10 seconds and go. Modern day cars should be warmed up while they are moving, not sitting still. Regardless if they have rotors or pistons. Just stay below 3-4k until engine is properly warmed up.

Double clutching does not fix my problem haha. It refuses to go into 2nd UNLESS your at 7mph or less. It doesnt just grind while trying to go in. It also refuses to downshift from 4-3. 3-2.
its borked dude. =) found a ball bearing inside of my tranny fluid. Charles says its my 3rd gear detent check ball. and a **** ton of metal slivers on the magnet.
but this is totally off subject!

lol's I'm glad I get to keep my 8 in the garage nowadays, I just start it for a while and go feed/maintain my fish tank in the garage then hop in and take off (under 4K usually).
ps, sux about your tranny

Driver her away once high idle ends, keeping it below 3K until warmed up. Which for me is about the time I hit the on ramp for the interstate...then it's ZOOM ZOOM!
If I thought I had to wait 5 minutes before driving my car I would have thrown her in a lake by now. You are WAY more patient than I am...

When people say "let the engine warm up first," all they really mean is don't start it up cold and drive away immediately, revving up to redline like you do when it's warm. That's all you have to remember.
So yes, 10 seconds is probably fine if you drive gently (not over 3K rpm) for a few minutes 'til it warms up. Waiting 5 minutes definitely will mean the engine's warm, so you'll have absolute peace of mind. But it's really not necessary, wastes gas, and it's not what Mazda wants you to do. (Don't confuse it with the "don't turn it off 'til it's warm" rule for avoiding flooding.) I might left the engine warm 5 minutes first thing in the morning if it's subzero cold out (like when moving the gearshift feels like stirring tar).
But normally I just wait a minute or two before driving off, and then drive gently 'til the temp gauge reads normal. Killing time? That's easy. By the time you belt yourself in, adjust the radio, seat and climate controls, you're good to go.

It is probably better to warm up the car while driving gently (of course after the rpms fall down to around 1200-1000). If you idle and wait to warm up you run rich which is not the best thing for our car.
What's up with the Greek picture you have on your first post??? Are you Greek?

It's not like warming by idling is an absolute no-no. Internal combustion aircraft engines are warmed by idling before takeoff. There's no choice: no such thing as taking off at low rpm til that warms up. But for a car, where there is a choice, it's better to do it under load and low rpm. And aircrft engines are rebuilt at intervals way shorter than the expected life of an automobile engine.

I do both. I let her warm up for a couple of minutes at idle and then I drive gently never going above 4,000RPM until my oil temp is at least 170F. I have gauges. Some of you guys would be very surprised to know how long it takes for the 8 to warm up completely.
Even when my coolant reaches operating temp the oil is still at only 150F in 90F weather. And keep in mind that I have a real oil thermostat (reverts oil back to the engine until it reaches 180F) so likely that oil temp number is quite a bit lower for you guys running factory oil cooler setups.

I dont think theres a difference between 150F and 170F for modern oil. especially in the winter the engine never reaches that high.

You don't think there is a difference? I guess not between 150F and 170F but I didn't say I started beating on my car at 170F either, that is just the minimum temp at which I drive regularly but I would never red line my car at that temp. I also measure oil temp on the return so you can bet as soon as it enters the block again it heats up quickly. You should read up a bit about motor oil and viscosity
On a stock oiling system there is cold oil flowing due to the lack of a true oil thermostat.

well, ive been rotary since 1981. Have had 10 different Sevens and now an Eight. I am a firm believer of warm up and cool down. And as a datapoint, I have Never had an engine failure.
