Oil weight

[Silverdodge]

Let's talk oils for s moment I live in northern Wisconsin and have always ran amsoil 15w40 now realizing I can't plug it in I'm going to try there 5w40

Is there any real difference

[Guest 04Mach1]

5w-40 will give better flow characteristics when cold. You could see a minor increase in fuel mileage too since the oil pump will use less energy to pump the 5w-40. I've been running Rotella 5w-40 in my 01 year round for atleast the past 6 years with zero negative effects.

Looking at the Amsoil spec's there isn't a lot of difference between the 15w-40 and the 5w-40, but the 0w-40 has an additional 14°F protection.

 

The hot properties of the 0w-40 are also better than the 5w-40. 

 

I would personally get the 0w-40 over the 5w-40.

Sure didn’t wait too long for answers. 

 

If you ordered online you can probably call them when they open in the morning if you want to change.

I can see that during the warm-up period but after that point the viscosity is the same between 0w-40 (15.7) and 15w-40 (15.6) so there is no gains to be had after warm up. 

 

Just a point of reference for folks. 

40°C is equal to 104°F

100°C is equal to 212°F

I buy in person at a distributor near me for cost 

What I put in cost me 23 a gal retail is 30 a gal so ya makes it worth it to but it at that price

Technically if anyone is interested in getting amsoil cheap and wants to order I could have it shipped

I’m a dealer and do it the same with a direct jobber down the street. 

 

I’m going with DME this change, and I’ll be picking it up tomorrow. 

 

But honestly the 5w-40 doesn’t have the specs to warrant going away from the 15w-40, when you consider all of them. The 0w-40 does, if you need the cold protection. Keep that in mind for next change.

Gotcha, no 0w-40 available outside of signature series. 

 

I didn't even think to look at ADO or ADP as I normally only look at their oils with extended drain intervals for non-DPF engines. 

 

My dad runs ADP in his '17, since has has to change it every 6 months (or mileage which isn't often) for his forever warranty.

Yeah idk I can get mine every 5 to 8000

Yeah, if you’re changing it that often (unless it’s a year) the ADO and ADP are plenty. 

[Silverdodge]

Yep every 3 to 4 months
