I live in Canada and it gets topic cold up here.Winter time I plug in the block heater over night.Even in my garage.I run full synthetic for obvious reasons.I will generally warm my car for 3-5 min the take it easy till everything is warmed up..
Summer time it's about the same,only difference is I don't plug it in.Imo warming your car for 15 mins is pointless as your car will heat up quicker when you drive.I too have read on the Internet about warming vs not..experts say don't and I think the experts are getting there pockets lined with $$$ for saying so.anyeays just my 2 cents.

 

Pockets lined with what? Money? For saying DON'T spend your hard earned gas money idling for no reason?

The people who say you need to warm your car up more than 30 seconds before you drive are the same ones who say Climate Change is not accelerated by humans. Best to ignore them like they ignore facts and look forward to the world being a better place when they're dead and decomposing.

 

I leave mine running for a minute or so, but I keep it below 3k when driving until the engine is fully warmed up.

 

15 seconds on idle and slowly drive away. No full throttle for 15-20 minutes in winter.

 

I am in Chicago and it can get cold also. If my car sits outside in the winter, (especially outside) I will watch the rpm gauge, once it drops to around 1000 to 1300 (or the engine doesn't sound too loud), then I slowly ease into the drive until the vehicle reaches optimal temp for more acceleration. Do not waste minutes idling, that gets you 0 MPG and is a waste. All a 30-45 seconds then slowly drive off. Allow temp to rise before accelerating at a faster rate.

 

Most "normal" driving and shifting on the G is done in the 2,000-3,000 RPM range. Just stay in that range for the first 5 minutes in moderate weather, maybe 10 minutes in cold weather - and you'll be fine.

 

The quickest way to warm up a car is to drive it, but not accelerate hard until it reaches maximum operating temperature. I usually wait until the SAI pump stops and than drive it (10 seconds or so).
Prolonged idling leads excessive carbon buildup.

 

But what if it takes 10 minutes of idling to even see out the front of the car? My car must be filled with carbon.

 

Aggressively rev the engine to 5000 rpm

 

This is exactly why I have been laughing at everyone saying they let it run for 30 seconds and then take it easy. It doesn't always work out that way. In the past 2 weeks alone I have had to let the car idle for at least 5 minutes before the windshield even starting clearing. And no, I am not talking about ice on the windshield, I am talking about fog inside and outside the windshield
that the wipers won't clear.

Again, even if it isn't fogged over, warming the car up is more for my benefit than the cars.

 

i find the defroster especially the front windshield defroster sucks in our car.

I'll have the heat up and AC button on and press windshield defroster and it does nothing, I am FORCED to wait 10 minutes to clear up slightly.. honestly better just wiping the damn windshield with my palms from the inside.

thats one thing i hate about this car.

 

I assume you don't drive as G37, since they don't have a SAI pump.

 

Idle for 30 sec tops, then low RPM til oil is warm.

My car is subject to infrequent and short trips (commute by metrorail), probably not great for it but don't expect it to substantially impact reliability/maintenance.

For the first few months of ownership, still lived out in the 'burbs, and boy did I hate having to clear the windshield every morning (well, during the winter).

 

I did notice the defroster in my G at least does take a tad bit longer to actually clear the frost. Especially the rear.

 

This morning was another example of how 30 seconds isn't enough to drive the car. Went out, started the car, scraped the ice off the windshield. Went back in the house, gathered my lunch and things for work, went back out approximately 4 minutes after starting the car. There was still fog on the inside of the windshield that was just starting to clear up. It would not have been safe at all to drive that way.

30 seconds may be all the ENGINE needs to go, but there are other parts on the car that are vital to driving that may take longer...
