I would like to announce my rebourn faith in the na rotary engine. Today it was -25 degrees celcius (-13 degrees fahrenheit) outside and my car managed to start with no block heater!!! on 20w 50 oil!!! i do feel sorry for it though and wont be doing this ever again, but still its nice to know she can start in these conditions.

 

-13 F?!?!?! OMG man its around 20 F here and I think its frickin FREEZING. My N/A decided it wasn't going to start for me last night...it always does this **** in the winter.

put some thinner oil in there

 

Damn, it sounds like your fuel injection setup is still actually working perfect after all these years. Props.

 

It should never be a problem to start in the cold. My FC ALWAYS started. Hell, my carbureted '78 1st gen always started. If your car is working properly, cold start/hot start problems should be nonexistant.

But by god, put thinner oil in there. 20W 50 is nearly solid as these temps. Hell, this morning even the 0-20 in my Insight was like syrup.

 

"Should" is the key word.

 

lol, I've never even heard of 0-20, my god I don't think I could live up there 10w-30/40 is almost to thin for around here. I put nothing but 20w-50 in all year round and straight 30w when I used to have my old 626 beater, lol. One day I'm going to have to go to Canada just to see how cold it is there.

 

My old 88 gxl never and i mean never once not started. It only flooded once the whole time i owned it and that was cause it hadnt run in 6 months and after i pulled the injector fuse it fired right up. i used to drive it every winter out here in maryland

 

Mine started up fine too in -30C ...
However, I have 10W30 with MMO in the engine.
MMO helps startup alot.

 

-25f is the coldest i've attempted to start mine in, turned over like it was being hand cranked, but started!

 

Damn it, it finally snowed once and I already want my summer back!

 

That's because it thins the oil. Of course, the side effect of this is that the oil becomes a less effective lubricant, and it causes oil starvation (since the oil is now diluted).

 

Mine started on 0F weather yesterday. I was happy. The gearbox wouldn't shift for a while though - I suspect the 75W90 in it was basically a solid block of goo.

What's always impressed me is that my sub-beater (basically, rolling shell with an engine/transmission in it) has always started for me. Even in -10F weather, when half the town can't get their car started, this one will crank & start.

My FC has always started in the cold (if you can call 27F cold) It's just building up oil pressure when it's cold out that seems to be the problem.

 

No. I (and most people to the north of me (middle of Iowa)) consider a 27 degree day to be "quite nice" - especially in the spring.

And then there's those crazy Alaskans... "It's not cold till it hits -40." Funny thing is, you don't need to specify scale, because -40F = -40C.

-=Russ=-

 

Michigan gets weather that cold as well. We've had quite a few -40 days.

 

My car only has a problem starting when it's warm or hot.

 

You're right it shouldn't. But my N/A has right around 210,000 miles on it and the compression is not the best. I just need it last a couple more months till my TII is done.

Pshhh.... 27F is a nice day here.... I run with the top down on days like that. It's when it gets nearer to -10F or so that the 'vert even shows signs of trouble....

 

my rx always started faster in the cold than my piston car.

 

LOL. the responses here are so varied. its funny cuz i saw an rx-8 on the road today gettin towed away. maybe the new renesis duznt like cold.

 

Yesterday in -15C my BLOWN ENGINE TII started..

I think that's pretty damn impressive.

it was a bitch starting my borrowed tempo today.

 

hahahahahaha ^^^^^

 

Compression should be higher when it's colder out I believe...cold starting (like in o degree weather) is a test of your charging system as the battery has LESS of a charge and the alternator has to work HARDER.

 

My engine starts up fine in colder weather, of course it's only gotten down to about 30-40ºF at lowest here right now, so it's not too bad yet.
