Was looking at the owner's manual for recommendations on first oil change and although I have three thousand more miles to go I thought I would pick up a filter and oil and have it on hand. I see there is number of different recommendations for oil and 5w 30 is listed which I put Mobil 1 5w 30 in everything else I drive. I was wondering what the advantages are, if any of using 0w 20? If it's a temperature thing? I will not be driving the Niro when the snow starts to fly.

I also intend to use Mobil 1 5w-30 oil. My personal belief is that 0w-20 is too thin for the hot climate. I think 0w-20 was come up with as a way to eek out a better mpg's for marketing reasons. Also our local Kia dealer uses 5w-30 as a matter of regular course and they swear it's Mobil 1 :eek:

My 2018 owners manual only recommends OW-20. Had my first service today! Not losing a thing in any temperature. A good part of old cars specifying much heavier oils is that viscosity quickly deteriorated. That's why 2,000 mile oil changes were commonplace, and some still believe in them. Engines, cooling, oil, and filters are tons better than that now, so using 30W-50 these days costs you big in efficiency.

I'd point out that the cooling system keeps your engine the same temperature no matter the outside temperature.

Kia dealers use bulk oil from Pennzoil I found out today. 5W-30 semisynthetic or base oil is a lot cheaper. Do you suppose that is why they use it?

I have no problem using the 0W-20 just wondering if it's better. MotorWeek had a segment on oil weight this week and Pat Goss says the it's the close tolerances in today engines that requires the thinner oil so it can lubricate all parts of the engine.
Anybody have a part number on the Purolator oil filter? I looked it up on Amazon just want to be sure.

0W-20 full synthetic is the only recommended oil for my 2018. It's superior oil to the alternatives mentioned here. I don't think I can post a link, but just google 'car and driver synthetic oil' and you'll come on an article 'seeing is believing'

FYI, Purolator filters are made in my home town...they also make just about every brand you can name in the same factory on the same lines.
