Hello,

Newbie and Yes i have searched and searched and searched!

But I cant seem to find the right answer or it is all over the place.


So I have a kia optima 2.0 turbo.. I have been using 5w-40 Pennzoil Ultra Euro ... well after my first change I put that in..

I am from London, Ontario... we see some cold weather ...
And i have been wondering since 5w-40 is both a summer and winter oil, I should be okay with it year round no? I know that it needs a bit more warm before i can punch it, but that was the way with 5w-30 as well.

So when optimal it should be fine no?
 
My opinion is that you'd do better with a good 5W-30 or 0W-30. As a generality, 5W-40 will be thicker at all the temperatures your engine will actually see, even though the "W" number is the same. And unless you're racing the car, you won't get the oil hot enough to need the extra protection a 40 grade oil will provide. The turbos are water-cooled so they don't beat up the oil quite so bad.
 
Welcome to BITOG, and welcome to a fellow Londoner.
What does the manual recommend for oil weights?
If it asks for a 40wt, you could always run Mobil1 0w40.

0w oils are great for our fairly cold winters.
 
First welcome to BITOG!

Yes what oil is spec'd for you engine?
As mentioned a 5W-30 will be lighter than a 5W-40 PU you're running now on start-up and Pennzoil Platnium 5W-30 is the about the lightest OTC 30wt oil you can buy for your climatethat may be preferable for winter use.

BTW M1 0W-40 is no lighter than the oil you're running now and the new PU 0W-40 (if you can get it) is lighter.
 
As CAT points out, "W" numbers are all over the place as are VI with in grades. You have to look at and compare only specific oil specs (and HOPE that the oil will hold published spec in the crankcase for a couple thousand km

Many may not. API/ILSAC strict specification for "stay in grade" killed the vi on many XHVI finished oils that existed during ILSAC GF4 / API SM.
 
Hey Guys and my fellow Londoner in here.\


The Kia Manual states the following

... The cap though says 5w30, the weird thing is the sonata t2.0 from hyundai says recommended 5w40 for optimal performance and it has the same engine..

Our engine has 9.5:1 compression with 17.4 peak lbs of boost on top of that…plus it uses Direction Injection. SO the chances of shear might be higher as some reports from optima users have reported. 0w is not recommended from kia !
 
Like others mentioned above, if you're not driving it like you stole it, the 5w-30 will probably give you better cold startup flow protection.

I would, but kia and hyundai can be bad on the warranty issues.


I was thinking of using the 5w30 Ultra from Pennzoil

but I think it meets the specs?

But dam it with the 5w40 my engine purs so nicely



Well I live near the border so i can order it from walmart.com in the big jug and ship it to the store for pick up.

Some people say it is a good OIL and close to the 5w40


I might risk it and use the 5w40 and see how it is during the winter and let the car warm up a bit before punching it..or just do 5w30 during winter and 5w40 during summer times


Also, sometimes i do punch it to get the turbo going lol thats why i bought the car... and some reports from other kia members have should 5w30 even with normal driving dilutes faster

confused mates!

They stated 5W-30 or 5W-40, so I would stay with that within warranty. Though a 0W-xx is the same as a 5W-xx for the hot side of things, I wouldn't chance it under warranty.

Do you know what API or ILSAC rating Kia requires? An oil I like for turbo applications is Shell Rotella T6 5W-40. It has an API SM rating among others, but no ILSAC rating. I used it in a 2003 Golf TDI diesel in Edmonton, and it performed wonderfully, summer or winter, so a London winter will be no problem for it.

If Kia requires an API SN, or an ILSAC rating, I would look for something else while under warranty, but wouldn't hesitate out of warranty to use it.
 
You can download the manual from Kia's website, so I downloaded the 2012 one. It says to use "API SM, ILSAC GF-4 or above", and there's a footnote stating that API SL can be used if SM is unavailable.

Given what the manual says, I'd still say to use 5W-30. But by no means should you drain the oil you just put in - it'll be just fine.
 
Look for an A3 rated 5w30, best of both worlds. Don't know what your oil market is like up there in Canada though.

Barring that, I think Castrol HM is 12.1 cSt in 5w30, that's closer to 40wt than other 5w30s.

BMW 5w30 is on the thicker side as well, but I bet the dealer is pretty proud of it. I.e. $$$$.
 
I guess the thing that really gets me confused why does hyundai sonota t2.0 which is the same engine etc as the optima recommended 5w40 for best performance!!

I might stick the 5w40 again in it and see how it goes can't hurt can it? since it does meet all the requirements and KIA says either 5w30 or 5w40

Doesn't specifically say which one
 
Honestly, I think you will be fine with either viscosity, so long as it meets Kia's other requirements. Some of us on here prefer to go to a heavier viscosity, and some prefer going lighter. In the end, I doubt you'd see a significant difference.

And this in itself is a conundrum, because I don't think any 5w-40 oil meets ILSAC GF-4 or GF-5. ILSAC is all about fuel economy. Xw-40 is not.

PU 5w-40 Exceeds ILSAC GF-5 engine cleansing and protection requirements

It does not.

Some PU grades do (the non-euro grades), but PU 5w-40 does not.

If you're running PU 5w-40 in your car, then pick up an empty bottle and find an ILSAC rating printed on it.

is the site wrong?

The site is not wrong. Why do you assume that this information pertains to PU 5w-40 specifically? There is a caviat that says "Specifications may vary by viscosity grade."


It's a generic PU page. It just blurts out all the different specs that various PU grades meet, but you should not assume that every single PU grade meets every single spec that is listed on that page.

Here is a PU 5w-40 spec sheet:

that is a little deceiving stating

I remember if my other optima last year i had 5w40 in it, before a little accident but our winter wasn't very cold last year!! but it ran smooth
