I got a 2017 5.7l first year I'm gonna be driving it in the winter. Wondering what kind of oil is recommended for winter. Can't find anything on Google. I'm thinking of sticking with amsoil 5w-20 for winter. Thoughts??

Why the stp? Did you read the labels? Just curious your choice, you like richard petty? me too, ha. See link below, mind you that is a pro stp treatment link, I can argue against that but wont. Just for the sake of cold, it is the wrong additive fore cold performance with due respect. It raises viscosty ten points, maybe a little less in a 7 quart sump, but still it will increase the grade of your oil, meaning in the cold it will be very hard to start your engine compared to oil w.o stp. I will leave you a chart of what viscosity looks like when cold, good luck to you.What’s your idea of winter? I’m in north Idaho and I stick to what the manual says.Quality 5w20. I also use Stp oil treatment.
My thinking was to leave a film of lubricant behind for the next start.I sell a lot of the Lucas oil stabilizer and it leaves a slimy film behind.But I figured Stp might have an advantage with its high zinc content.Or at least it did some years ago.For the record I’m a Rusty Wallace fan so I haven’t watched nascar in some time.Why the stp?

But for real, stp is a oil thickner not unlike lucas. It raises viscosity, so you raise a 30 weight oil to a 40 weight, or similar. Kind of the worst thing you can do for cold starts. link
STP oil is really thick even though you mixed it with oil but you need to remember one thing with the modern engines variable valve timing guess. And you’re going to greatly affect the performance of the car engine if you change the viscosity. It can interfere with the action of existing additives and even hurt your engine at a cold temperature.
You can see the differences 30 weight versus 40 weight oil and what cold does to viscosity. Operating viscosity of your 5w20 oem is oil anout 9, when cold stp oil treatment your viscosity can be near 18,000, versus around 4k at below freezing. Since this is a winter oil thread, I thought this relevant.

Got to come back, Kyle Larsen is the real deal and they got a couple boys coming up mind me of old school guys. But yeah it isnt the same, rusty was top 5 driver when he was driving and he made the sport better for sure.My thinking was to leave a film of lubricant behind for the next start.I sell a lot of the Lucas oil stabilizer and it leaves a slimy film behind.But I figured Stp might have an advantage with its high zinc content.Or at least it did some years ago.For the record I’m a Rusty Wallace fan so I haven’t watched nascar in some time.
I'm curious how you get STP to pour in the winter,lol.Growing up north of you in Saskatchewan,you had to put the can of STP in a pot of hot water on the stove before it'd pour in the winterMy thinking was to leave a film of lubricant behind for the next start.I sell a lot of the Lucas oil stabilizer and it leaves a slimy film behind.But I figured Stp might have an advantage with its high zinc content.Or at least it did some years ago.For the record I’m a Rusty Wallace fan so I haven’t watched nascar in some time.
I tried to get behind the guy in the number 2 car but couldn’t do it.That’s when I noticed Toyota had a car in the race. I thought what the heck is going on.Got to come back, Kyle Larsen is the real deal and they got a couple boys coming up mind me of old school guys.

So additives are what leave a film sounds like you have a good knowledge on that, but when the metal is hot it just sheds oil similar to frying oil for eggs. Thick oil has some advantages, but steep price to pay for winter though. Check out syn thread for some forum work on stuff that may help, lubeguard biotech high aw/ep additives plus esters that are known to leave film but is rather thin like a 20 weight for winter starts. Just a thought...
I see you are in my favorite place in the world, I love me some post falls. My brother lived there so I took some time up there, he couldnt make it work he would make good money in summer but not enough to make it through that long winter- he was drywaller. Beautiful area though, it is still in the back of mind when I retire and dont need to fight for winter income.
Another way to look at toyota's, someone to route against. Hamlin toyota front runner gets more boos then anyone ever, lol. Bubba gets some good boo's too since he went over from petty to toyota. I figured we'd see some more wallace's, I am puzzled why none of their grand kids took over the family business. peaceI tried to g behind the guy in the number 2 car but couldn’t do it.That’s when I noticed Toyota had a car in the race.

Ive done a little homework on lubricants.Rotella makes a great oil. I stick with the a good synthetic and get a good filter with synthetic media.
Post Falls is a great place.It’s going through its growing pains with the surge of new people.The fly fishing and hunting is amazing.Hiking is plentiful.Bring your bear spray. I appreciate the information and perspective.
This is a true statement. Besides altering low temperature oil flow, some additive chemicals can actually destabilize the motor oil and entirely deplete the benefits of some additives, and/or cause increased sludging. This is why most manufacturers advise against adding anything to the engine motor oil."It can interfere with the action of existing additives and even hurt your engine at a cold temperature."
