Brrr cold ! Oil for cold temperatures

[Ndx]

Hi Guys,

It's been very very cold .... Here

Oil temperature at start -18C ... ( Car shows oil temperature )
Oil pressure hits 4.0 bars ... Going super slow, car is frozen.

In normal weather I would be around 1.6-1.8 bar idle
Now I'm 3.6-3.8 bar

Current oil 0w40 Castrol

I need something that will flow better ... Car Cayenne 4.8 V8

Redline ?
Amsoil ?

Thank you

0W20 or 0W30 oil instead?

We have the same kind of temperatures here, I'm fine with 0W40...cause I don't have an oil pressure gauge on my car

I'm already out

(More seriously, I let it idle for a while before leaving)

You are fine, the Castrol is an excellent choice, I'm currently running it in my Jeep.

0W is good to -40 A 0W -20 or 30 would be thinner .

M1 0-20 works great in my Fords for cold starts.

Castrol 0W-40 has a pour point of -60C. Better than most 0W-20s (and the best cold performance out there for Porsche A40 spec). This is because it has a decent amount of PAO. I think you're safe!

I assume that his application calls for a Porsche A40 approved lubricant which means an HTHS >=3.5cP. M1 0w-40, Castrol 0w-40/0w-30...etc.

 

[Ndx]

Yes A40... Either 5w40 or 0w40 per manual ....


Thx

Wow, that is very impressive to my uneducated self. Thanks for the info sir and do we know the NOACK of current EDGE 0w40? Thank You again 1JZ_E46

So that "Brrr cold" will be gone in a few days...

And you want to change that 0W oil already ?

What topic will be next? Its "Uhhh hot"...do I need 20w50?

 

[dblshock]

Company ordered my CNG Kenworth to idle 12 hrs. last couple nites...electric oil heater not enough.

 

[benjy]

real synthetics like redline prolly as good as it gets

 

[Ndx]

Will there be differrence in pressure Castrol 0w40 vs RL 0w40

I have some RL0w40 kicking arround

 

[OVERKILL]

No.

 

[Audios]

Leave it, wont change much unless you go much thinner than spec. What does the owners manual call for in that range?

 

[dblshock]

5/30 conventional is good to -30F starts, colder than that stay inside don't travel..

 

[dblshock]

lot of disabled FCA, Subies and Nissans newer models, diesel semis galore here it the serious cold today as I ran loads today 460 miles w.shore L.Michigan.

This. Any proper oil with the specifications and a viscosity appropriate to the ambients is fine. A non-specified oil, such as the Red Line, may work just fine and may even have better cold cranking numbers, if we're picky enough to check, but probably has higher HTHS in the first place, which may be reflected in higher oil pressure under certain conditions, too. Basically, it won't "fix" the observed behaviour, which really isn't a problem needing a "fix."

headed out to work just now -18 '95 T-100 no worries...20mi.
