How detrimental is it to...

TreeSemdyZee · 01-10-2011, 11:05 AM

Um. If you didn't go over 3500, you're not really running it hard.

No issue, as long as it's not mine.

I don't think My Z will go fast when the engine is cold. Throttle response is very sluggish in cold weather until oil temps near 180. Granted, my car is parked in my icy cold garage for up to 5 days b/t drives.

Still, even after the oil temps are at normal levels, I typically won't get 100% throttle response until after I've shut off the engine and started it up again -- say, after a quick stop at the grocery store. I have noticed this more often in winter than summer.

Not knowing much about cars, I've attributed this behavior to the ECU perhaps trying protecting the engine. Am I right?

I also drive a 99 Mercury Sable. That car drives the same (slowly) regardless of the conditions.

On cold starts I tend to let the idle come down to normal or at least sub 1krpm before going anywhere and then keep it under 4k rpm until temperature gets to around 180.

I've had the issue a few times where I really want to play with someone when the car's cold and I haven't done it...I feel your pain.

^Same here. I try to be as gentle as possible when it is still completely cold but as it warms up, I generally increase the rpms and or throttle that I would allow and would never give it WOT until the temps hit 170 at least.

Why hasn't this turned into a lambo vs z thread?!

Haha, I agree.

SAE weight is about as accurate as stirring the oil with your finger and comparing it to honey, syrup, or pudding and then lumping it under that category.

Look at cSt at a given temperature. It is much more relevant to a combustion engine, where SAE weight is much more relevant to pouring a liquid through a small hole out of a bottle. Completely worthless spec. imo.
