warming up your car is ok, its safe and there is NOTHING wrong with it.
driving with your car cold is ok after about a minute or so if you take it easy
what do you think we do with inspections?!?!?!? we run a cold car!??!?!?
what do you think we do when we drain and replace coolant???? we put in coolant with the motor off and pull it out??!??! WRONG we put in coolant and let the car WARM up and then put in more coolant when needed.
oh no, all the techs must be destroying you cars, its a big plan
same thing with tranny fluid, we let the car warm up to operating temp
there is nothing wrong with letting your car reach operating temp or driving it cold under light load
please dont tell people wrong information

This way, you can prevent unnecessary stress on the car.
I would say though, most people let their car warm up so the heater is blowing nice & toasty on them.
JDMxB, how is warming up your engine bad (other than what I mentioned)? Isn't that like saying idling at a stoplight on cold mornings damages your engine too? I not trying to be a dick, I just want to know what you have heard. Thx!

Hey buddy--no need to be a smartass-not all of us are "CERTIFIED TECH's".
Here's a thought--how often do you do inspections, or change tranny fluid? I hope not as often as everyday when you drive the car. That's what we I was refering to. No ____, leaving it to idle once in awhile to do maint. is no big deal, but if you do it every single freakin morning--it would pose a problem.
Do what you guys want with your cars--but first read the instruction manual that came with it.

Had my XB for bout a month now and I must admit, I was one of those who sat there in the morning til the thing went away. Took a good 5 minutes, but I didn't mind... That was 5 more minutes in the box! I've since taken the advice of the all knowing forum and drive it normal...keeping the rpm's low!

I stopped that habit too. Thanks to this forum I even safe money on fuel now because not only did I stop using 91 octane(@ CA prices) , I don't waste 5-10 minutes of gas in the mornings anymore either. Thanks guys...

The blue light indicates that the engine is still cool, and that heat will be there shortly. As far as letting your car idle when cold out, the jurry will for ever be out on that issue. Some say yes, others no. My theory, i let the car warm up if it is more then a couple of years old, or has a decent amount of miles on it 25K+. But, warm up is not more then a couple of minutes, just to get the juices flowing.
A car sitting idle in Park is not the same as sitting idle in traffic or at a stop light in Drive. In drive, you are still putting a load on the engine, which is why the rpms are different then when you are idling in your dirve way.

OK.
FIRST:
If anyone thinks it is ok for you to start your car cold, and immediately drive off. KEEP DOING it MORON. Starting your car cold, and immediately driving it prodices the WORST wear on an engine. It takes 30 seconds- 1 FULL minute minimum for ALL the oil to reach every part it can lubricate. By driving immediately on those unlubricated parts, you a prematurely wearing components. Granted it may not be wear that is harmful once or twice, but I watch people all day long start their car and immediately drive it after it has been sitting outside for a day or two or even one night. Do you think your internal engine components feel good sliding metal to metal with oil between it, or with no oil? Do THIS TEST:
get 2 butter knives rub them together, now get the same 2 knives, coat them in motor oil. Which sounds better? which moves better? which one do you think after 40K miles of use will be in better shape?
Second:
I have been involved in MANY DYNO runs on many vehicles. We have done octane challenges, and believe it or not HIGHER Octane DOES boost engine performance. I have done Dyno Runs with 89, 92, and 100, 104 octane. The car is noticeably more responsive with higher octane AND the dyno numbers improved ever so slightly, BUT, after multiple runs and heat soak, the higher octane runs still held their HP.
Granted on today's modern technology maybe their isnt a difference between 87 and 89 octane. But no matter what I always use 91. From my 1990 VW with 215,000 miles on the original block, Mobil 1 oil, 91 octane, AND I warm it for at least 2 minutes every day. I do the same thing on my wife's 1992 Jetta and our 2003 Audi. Call me dumb, but the added security "just in case" is worth it to me, especially if it will promote longevity of my vehicles..

Whoa... why so serious . I actually don't start driving off right away in the mornings. Have to have that CHILL time in the box (look through the CD's, etc)...Thanks for the insight though. I'll probably continue to use 87 octane with about a 1-2 minute warm up.
