I was just wondering how long should we warm up our G's in the mornings, after a cool/cold night?
for instance if the temperature drops to 50 degrees(F) over night, when you first turn it on in the morning it usually revs to about 1.5k-2.0k RPMs...how low should the rpms be before taking off?
or should we go by the Temp guage?
I usually wait til it gets from 900-1100RPMs before I start driving
is that wrong? or does it really not matter?

 

As a rule of thumb you should let your car warm up until it's halfway to the normal running temp before driving.

Obviously not always possible, but if you want to be extra careful that's what you should do.

 

that's way too long..
on a cold start, i give it 30 seconds to a minute.

 

That's about what I do and it's recommended in the manual to do the same, then I take it easy (shift before 2.5k rpm) until the engine reaches normal operating temps.

 

I live in N.E. and it gets pretty cold up here. I'll get up an hour earlier than I usually do and go start the G and I let it run for about 30 min. or until it get to operating temp.

plus I use this time to clean of snow if their is any

Then I go back in the house do what I have to do and when I'm ready to leave it starts up nice and the wait time is cut in half.

 

Wow you are wasting a lot of fuel and energy. That is also hard on the car.

Why not just use a block heater on a timer. And start your car , clear the snow and away you go. Thats what we do in the Great White North .

Agreed. 30 minutes is extremely excessive and is overkill.

Someone correct me if I'm wrong, but the viscosity of our oil, if correct, will help lubricate our engines, even when cold. Yes, ideally, only operating the car (actually driving) until it's at normal operating temperature would be great, but I think most of us don't have the time to do so.

The majority of cars out there driven and operated by average and less than average Joes run easily over 100K miles and I guarantee 90% of them just drive their car once they start it.

I baby and take care of my current car and all my previous cars, but don't stress over the small stuff.

 

even if it's 0 degrees outside, snowing.
I start the car, go out and scrap the snow and ice off.
that takes me about ~ 2 minutes and I drive off...

especially if you live off a small side street, the car will warm up within a mile and the race begins

 

^^^^ Perfect. Exactly what I do

 

Block heaters are standard in Canadian models for 2nd gen g35s. Not sure about 1st gen. Just a tip for the Canadians out there!

 

block heaters??? what the HECK are those things? Sorry, I'm from Texas...

 

Block heaters are also standard in 1st gen Canadian G35s.

Block heaters are usually heating elements that are put in place of a frost plug of your engine block. They are heating elements that go right into your water jacket of your engine block.

You plug it into an outlet at home and it keeps your engine warmed up during the cold weather.

 

any pics of it in action ??

 

There is a huge disagreement on RFD (a candian forum) about this before. I will let you know what I do (and I don't even have a block heater; haha) when it is -40C outside here in Winnipeg... I let the car drop to 1200 RPM (takes 45 seconds); I then proceed to drive the vehicle but keep my RPMs below 2100 RPM until the engine temperature is at normal. This warm up period takes 4-5 minutes in -50C weather; I do run 0W-30 to help the oil not sludge up as much especially when I do not have a block heater installed.

Apparently if you let your car run for more than 30 seconds it stresses the transmission/engine and driving the vehicle but keeping the RPM is low a better method of warming it up. I don't drive on the highway too much but obviously you cannot be creeping around at 40 km/h on the highway.

 

. It is a plug that sticks out of your bumper (for G35 it is outside of the bumper mesh); you need an extension cord and you plug it into an electrical outlet. All the parking lots in Winnipeg (and probably most of Canada) have a place where you plug it into and it keeps your oil level at an ideal temperature (otherwise it will sludge up and freeze). Up here we have sometimes been hit with -50C temperature where the oil would literally freeze; if you don't have a block heater you will be screwed.
