Heavier oil in the winter

[mbar1]

This is my first winter driving my V8 2016 Camaro SS (same engine as the Corvette).
As part of this forum recommendation I switch my oil from Stock 5w30 (Dexos1) to 0W-40 Castrol Edge for Track Day use/daily driving.
From day one in the car (summer) while standing in a traffic light you could feel the car shaking a bit (feeling the V8 moving the car). I assume it normal when you have a big engine.
Question: now that temperatures dropped to the 20's and 30's the shaking is more intense. Do you guys think it's just because it's colder or because I'm using a heavier oil?
Thanks!

My Impala doesn't idle quite as smooth (very very minimal) when it's cold out, but I assume its just the slight air density difference.

The oil probably has no relevance here since you went to a 0w-40 and not something like a 20w-xx

Motor mounts stiffen in the cold too

It's likely due to the engine mounting system. Rubber is generally not as forgiving when the temperatures are colder and any fluid-filled mounts will likely be tighter as well, as that oil/grease becomes heavier with colder temperatures. In general, I would say that this concept (more engine feel in colder weather) is not noticed with most powertrains, but certain scenarios where an engine is a little lumpier than usual, or a certain mounting configuration is sensitive to that harmonic, could experience such a difference with temperature.

I'm running 0w30 this winter in my Focus, I usually run 0w-20 in the car. No difference in cold start noise or engine vibration.

I decided a poly engine mount was a good idea, so if there was an increase in vibration or the engine being rough, I would feel it for sure on the cold mornings!

Count me in for it being cold/stiff engine mounts.

$40k+ for a Camaro to be driven in the salty snow?

The easiest thing to do would be to swap change the oil to the lighter grade and see what happens.

People drive their $100,000.00 semi trucks in the snow so why not.

The compromises one have to do in life

I preferred it over 35K older Camaro with a 5K winter beater. Some might disagree

My vote is for stiff engine mounts.

 

[IndyIan]

Cold motor mounts is my guess too. Only with my carb'd atv, have I noticed a difference in cold idle speed, and it was going from 5W40 to 15W40.

Semi trucks don't rust out near as much as a car.

This. My truck is rough when its cold for the first few miles.

$1,000,000 really. 2017 Kenworth T680 brand new with "0" miles $155,000 more or less.

Thanks for all your help!

I totally agree with you mbar1,unless someone discovers the fountain of youth,none of us are going to be here forever,drive it and enjoy it,that's what it's made for

. I don't understand the garage queen mindset. It's like someone on here once said,why keep it mint for the next owner? Drive it and enjoy it!

2011 Corvette here with LS3. The idle lope is intentional. It was designed into the idle engine management because it was thought that consumers wanted to have the lope remind them of old traditional V8's. That same engine in other vehicles, like a Tahoe, idle totally smoothly, and if you wanted you could have your engine tuned to take the lope out (thought that could potentially void your warranty).

But yes, the lope is a bit worse when cold until the engine mostly comes up to temp. And yes, I left it in there when I had my engine management tuned.

I read this as $100k.

I did a tuneup with injectors ultrasound cleaning and the engine got smooth again. It wasn't misfiring, but I feel the difference clearly.
