For my commuter car I have a 06 sonata 2.4L with 163I miles car runs like new never had a problem with it I've used full syn for most of my oil changes but not im going back to Dino because I like a shorter oci my question is in the owners manual it says to use 5W20 in conditions 32 or below or all year it has 5W20 on the oil cap. But it says in the manual you can use either 5W30 or 10W30 in conditions above 32 if I remember correctly. So my question is what viscosity dino would you run for out 110+ degree summers

I would run 10w-30 in the summer, and 5w-30 in the winter. No need to stray from the owners manual. You dont beat or race your car so a 30 grade is fine.

Way would you change oil with only 1631 miles on it???

Just kidding.

I would go 10W30 if that's what manual said.

I would definitely use 10W-30 if it were me and it was that hot and using conventional. (And I would probably use Rotella!)

I'd use the 5w30 if it is approved although 5w20 would work just fine.

5w30 all year. Use any major brand on sale (or your favorite) I really like Mobil Super 5k or PYB. 10w30 is really not worth running, there are almost no benefits if any to its usage. Run 5w30 all year.

Pyb 10/30 but PP 5/30 would be perfect.

5w30 year round takes the hassle out of worrying about changing oil weights.

My mom has a 2011 Chevy Malibu with a 2.4L. 5w30 delivers proper protection and better start up than 10w.

I'd use a good 5w30 synthetic all year 'round.

Sure there is. A 10w-30 tends to stay in grade better than a 5w-30. If its direct injection then that might make a difference.
Op. maybe run your 5w-20 and do a uoa then run a 5/10w-30 and test it as well. Then stick with the one with better wear numbers.
If you are going to run thicker oil might as well get some data to justify. It could be that you get better wear numbers with 5w-20,or maybe not,but it wouldn't hurt to know for sure.
Just a thought.

If you're in Vegas you could run either 10W30 or 5W30 year around. I wouldn't even bother with 5W20 in this case.

If I'm reading that mileage correctly (163k miles) then that's about 25k mile per year. And I guess in the Vegas area you're doing quite a few of those miles in hot freeway driving.

Personally I wouldn't be going for shorter OCI, I'd be going for a good quality synth and longish OCI's. I'd be picking up a nice hefty ACEA A3/B4 rated synthetic (either 10W30 or 5W30) and running it to maybe 10k miles over summer.

Run 10W-30 in the summer, 5W-30 in the winter, ESPECIALLY if in winter you go to places like Ely.

Just use whats listed in your owners manual.

We've discussed 5w20 Vs. 5w30 questions on this board almost every week now.
