I took my car in for it's 7500 mile service (oil change and tire rotation) and on the next oil change due sticker, it states 5-30w but our manual suggest 0-30w.

I know that it shouldn't matter much but what would the goods and bads be?

Thank you

I thought our manual states 0w20 which is full synthetic.

I would call the dealership and ask why did they didnt use the correct oil.

- slight gas mileage reduction

Thanks for your response. I am most likely wrong on the manual saying 0-30.

Now that you mentioned it, it does seem like I'm getting slightly less gas mileage. I would hate to call them if it's not that big of a deal so I wanted to hear what some of you say first.

Do you have the 2.4L engine?

You need to double check your Owner's Manual for the correct oil specifications.
There may have been a change due to the change in motor size, but don't just guess at it.
- MPG Will be effected with the higher weight/viscosity oils - even if it's by a small amount.


Here's a list of Maintenance items (Keep in mind this is for a 2.0L motor. But, the info is still relevant.)
As reference, the proper oil is 0W-20 Full Synthetic for a 2.0L

Synthetic? Really? That'll cost a fortune.

Not really.. $28.99 5qt. jug of Mobil1 at local big box Wallymart.
I'm sure it'll cost twice that at the dealership.

Thanks for the info! I have the 2.0L and you and Cottage are right, the manual says 0w-20. I called the dealer to ask and they said based on their computer records they put in 5w-20. The sticker was wrong.

Is 5w-20 also considered synthetic?

5W20 is part synthetic or synthetic blend . it also can come in full synthetic . with the heat of South Carolina 5W20 should be fine in your OS . you will loose a little mileage 1 or 2 miles a gallon . in the winter time you might want to make sure they use the 0W20 Mitsubishi recommends .

Losing about 2 mpg is about right. I will definitely make sure they put in 0w20 from here on since I drive over 500 miles a week. Every little bit helps haha.

Thanks so much!

Hopefully that oil change was on the house!
If so then go ahead and run it for ~3,000 miles (or 3 months which ever comes first), then get it flushed and replaced with the correct viscosity!


Cause at this rate.. you're Buying about 8 additional Gallons more per week than you would normally, IF you just had the correct oil... traveling at those kind of mileages.
sh!!!ts, that's $20.32 More in gas per week (based on $2.54/gal.)

I'm no accountant but if you extend that out to 4 weeks then 3 months, your wallet will be $243.84 lighter than today.
