Longer ignition/crank time with 5W-40 Dexos2

[mbar1]

Hi guys,
In a previous thread we discussed the owners manual requirement for my 2016 Camaro SS to use Dexos2 5W-40 on are road course/ track day due to elevated oil temperature.
Last week I replaced my oil after 1500 miles break-in to Valvoline Synpower MST 5W-40 Dexos2 (http://content.valvoline.com/pdf/synpower.pdf). Since the switch I noticed that cold start ignition crack takes another 1-1.5 seconds. Is this normal?

Thanks for all you help

How does it run once its warm? Did you go to a different oil filter?

I would not worry. 5w30 Oil is a LOT thicker near freezing than that 40 grade is at 10C.

Same oil filter (stock) . The engine seems to run normal. Also If I restart it again after it's warm (stopped for 30 min coffee) , the ignition crank time is "normal" (not long).
However, every morning the crank is a little longer than what it used to be (1-1.5 second).

What oil did your car come with, 5W-40? An additional "1-1.5 second" cranking time is really almost not measurable in real world operation without expensive instruments. Even so, it's nothing to worry about, enjoy your new car and drive it for a long time.

Maybe in the dead of winter in subzero temps, not during the dog days of summer.

Thanks. The car came with stock Mobil 1 5W-30.

+1 Even though it's a new car.

Also check your battery connections.

I think it's fairly normal for a cold start to be slightly longer than a restart, even in hot summer temps. But if you begin to notice an increase in the delay it's usually battery related in my experience. I just replaced my failed battery today and had ignored a slightly increasing cold start time for months.

IF he had jumped all the way up to a heavier 20W-50, or 10W-60, I would expect a hair longer crank time at first cold start of the day, even in the dead of summer.

But probably not from just going up to even a Euro spec 5W-40.

the 5w40 might be a tad thicker compared to a 5w30 when cold but not tnough to increase cranking time

Even if your car is new, some batteries fail early.

It happened to my 2010 Lancer Ralliart. I know the factory battery was replaced because cars built in Japan because they tend to use Yuasa or Panasonic. The battery that was under the hood when I got it was a JCI battery with Mitsubishi logos on it.

I think the same thing happened to one of my mom's cars, but I don't remember for sure.

Happened to my 2010 Colt Ralliart too... Mitsubishi battery lasted only 3 years.
Mistubishi/Smart branded battery my gf's 2005 Smart Forfour lasted 10 years and was replaced only because I found a new one for cheap...old battery still in service in the Barchetta !

That said, above ~10°C, I haven't noticed any cranking difference between 0W40/5W40/10W40/10W60/15W50 I tried over the years in my diesel (I know, starter motor probably overkill in diesel engines). Engine smoothness after start-up is another thing!
