:iono:wonder if someone from a COLD place running turbo can budge in....

What does cold have to do with it, outside of cold start?

I'm not talking about anything outside a cold start...

Information based on oil to run with Turbo, and temperature on this platform seems a bit scattered. Talked to tuner and performance shop, they could only relate to it from hot climate (Florida). If I look at Subaru's charts separated by oil and model, well they're separated by models, so that's a NON Turbo BRZ.

Maybe I need to post in regional section.

I don't understand what youre asking. The car has thermostats to set a floor operating temp, and a cooling system to (theoretically) set a ceiling operating temp. This is regardless of whether the car is in -40F Canada winters, or 130F California deserts.

Don't really know Mike. Yes I have aftermarket cooling mods. My engine builder said he guessed the studs stretched from being boosted and the head lifted.
Been running 10-40 based on conversations with Phil Gabow at Element Tuning.

I did experience the fuel starvation issue one day at streets of willow, last turn before the straight. CCW, so that might have caused it. Normally I always top off my tank between sessions but that day I forgot to.

I've just heard of "cold start damage"... I'm running 5w 30 right now in FL, I've just heard if I'm going to be in the cold, I should get 0w 20 or 0w 30, I haven't really found any sources on that, or anybody that can relate to the matter.

5w 30 should be fine for you in Florida as it doesn't get too cold out there.

Sounds like it's time for a surge tank for you!

Sorry, I completely left out the fact that I will be taking the car to Colorado lol...

Says your turbo'd and in WA? What oil have you been running during winter there? (while turbo'd)

I used to run 0W 20, but have since switched to 5W 30 for the past 2 years. Our winters aren't too cold so I don't worry too much. Something that helps a lot is the Torque App that I downloaded, if you enter a custom PID (the thread is somewhere on here) you can get it to read you oil temperature for extra security.

If you live somewhere that constantly gets snow in the Winter, I would switch to 0W 20 for the Winter months.

Could be.

Ok, honest question, I'm a southerner so define too cold. Colorado is ranging from 20s to 40s right now.

I am actually running Torque Pro. An Oil pressure gauge would make me complete though.

I have 1000 miles left before my 3000 mile mark on my current oil (5w 30).

Are you driving short distances or long? If you do primarily long distances you could get away with 0W 30. For short distances OW 20 probably better.

Why is 0w 20 better for short distance? I understand the oil temp gets higher on highways, but with spirited driving in "short distance", wouldn't that be the same effect?

I do plan on buying a cheap daily to get me around and drives to Denver, just depends on how snow is over there when i get there. I will say, I don't see too many people running 0w 30
