Is anyone else trying to drive thier cars as little as possible in the heat wave? More moisture means less air the cars breathe and the added heat of 40+ cant be good. mines been sittin for days. I'll prolly take it for a spin on friday.

 

Well extreme cold and extreme hot are both bad to our exotic rotary engines.... :P

Try not to get stuck behind traffic jam, and even if you have to, keep more space in front of your car...albeit its hard for me travelling from downtown north...$^$%^

 

Have not been driving mine this week only because I sprained my left ankle. I would think the rotaries' would love this thick humid air.

 

Been switched to drive back my RX-8 four days ago, to avoid my RX-7 in the hot weather...... FD are very hot for sure, if I keep driving it

 

i thought rotaries would like cold crisp air? shows what i know.

 

I've been getting good mileage but I have also not been driving hard at all.

513 kms before the fuel light came on.

 

513 kms?! that's unheard of for me haha not even on 100% hwy

but my car's been losing power when the coils get too hot since my coils are dying. So if i drive for too long, I'll have problems accelerating, need to switch them out soon.

 

513 km??? holy ****... that must be like pure highway at 100 km/h cruise control!

 

Nope. Hamilton (basically right on the Red Hill) to Oakville (Third Line and South Service Road). I usually take New Street/Rebecca instead of the rush hour highway.

Looking at my notes, I got that tank at night when it was 15°C out(looking at The Weather Network, I don't keep track of temp). Maybe a case of 'free' gas since it hasn't been below 30° when I've been driving so the gasoline would expand a bit.

 

humidity helps with the cooling. your radiator/intercooler will be happy.

 

Is it just a subtle loss of power or actual misfiring? The ECU seems to retard timing by design when it is 35 deg+ outside and you've been driving for a while. After my first summer with the car I've learned to just park it during that one week of heatwave in June every year.

 

my car feels like a slug even without the AC on....this weather just feels like i am killing the motor.

 

Think of it this way, people inject water into the combustion chamber to lower the intake temps (water has a high specific heat capacity). Humidity should help lower intake temps. (ie. 34C with humidity should be better than 34C without humidity)

 

I've been stuck with hour long commutes to pick up my daughter from work... Burls to Brampton to Sauga
So I drive without AC to try to be nice to my engine...
Must change to 5W30

But really it's been running well, sucking gas and money like a sports car should

 

Better get those coil in before the 16th, don't want you dying in the middle of the track.

 

my car runs better i find shifts and idles better ?

maybe its just the odd 8

 

I took the family to Oshawa yesterday from Peterborough in the 8 and it felt fine even with the: AC on full, two kids in the back seats, wife in the front, two strollers in the trunk and the temp on the dash never went below 32....

 

And I thought I was the only weirdo. Mine's been parked since Saturday. Decided not to take it to Toronto, but the Element instead to save the mileage, and then haven't driven it to work because of the heat.

Today I caved though and took it. I just missed my baby so much, and it felt sooo right just being back in that car! Started up like a dream after sitting a few days.

 

The humidity isn't going to hurt your engine like many said. There are dozens of days a year where the humidity is at 80% to 100%. We just all notice it more when it is hot out.

Every time it rains the humidity usually ranges between 70%-100%, yet we all drive in it. There are even days in the winter where the humidity hits 80%+

The heat is what's killing our engines

 

Coolant still doing its job though.. I ran scangauge while driving.. still kept at around 98 to 104 C

 

Hot/humid air is the thinnest air, just the opposite of cold/dry. All internal combustion engines prefer cold/dry air.

Weather guessers also use the term "thick humid air", but they're referring to the preceived difficulty in breathing.

btw: for sprains, "RICE":

Rest
Ice (to reduce inflamation)
Compression (e.g. Ace bandage to reduce swelling)
Elevation (above the heart, so as to facilitate draining)

 

^No "RICE" here haha

 

lol rice

 

Cold air is obviously more dense than hot.

But I'll take hot and humid over hot and dry.

 

I'll take hot and dry over hot and humid any day. At the same temperature, humidity just adds on and makes it far worst.
