Switch from 5w20 to 0w20

[beadvised]

I have a 2007 Kia Spectra Ex. Currently running 5w20 dino MS5k. Could I switch that over to a 0w20 synthetic?

No problem.

 

[dparm]

Absolutely, even if you don't live in a place that gets very cold.

Just like the Gents said above--->Yes you can!!

You might even extend your OCI a bit longer as well-->Maybe!
Since the cost will be a bit more-->justify the extra cost.

What you are using now is absolutely fine but if you want to switch, as SyN and dparm stated, it is absolutely fine and should allow you to extend the OCI's some.

In most cases I believe the 0w is of better base oils except maybe the PU 5w20.

I wouldn't hesitate switching either direction. I just put PU 5w20 in the Civic since I got it for a steal.

OW-20 oils definitely use lighter base stocks than 5W-20 oils hence their higher viscosity indexes.

I would stay with 5w-20 and,maybe,a syn blend. I would be a little concerned with oil leaks.

0-20 wt oils don't cause leaks any more than 10-30 will. Both of my engines are bone dry with 0-20.

Concerned re the better flowing 0w-20 syn vs. the op's 5w-20 conventional.

I read on one forum that some techs have noticed more consumption with 0w20 than 5w20 on the newer Toyota models. Can't vouch for that myself, personally, but I do lose between 1/2-2/3 qt at 10k service intervals on my DD Prius.

1/2-2/3 qt at 10K is a pretty decent oil consumption rate.
Remember all engines are designed to allow some oil past the rings.

When I first bought my Duratechs I used 5-30EP. After discussing oil with Johnny and Fsskier I switched to 0-20AFE. No consumption increase at all in 10K.
