Oil change

[thekonn]

hi all, i just got my first oil change today on my mazda3. the dealership put in w5-30 instead of w5-20 which stated on the oil cap. they told me that both w5-20 and w5-30 are about the same. Is that a correct statement. or should i go back to the dealership and have them put in the right one?

thanks konn

5w20 was more for mileage and emissions (my understanding)

the rest of the world runs 5w30, and we run 5w30 in the MS3, so in theory you should be ok. But it's also your right to have it done with the proper oil

I have alway thought of 5w-20 as an oddball oil. Certain cars say to use it but I could never understand why exactly since the engines were very similar to engines that ran 5w-30. In other words I wouldn't worry about it.

thanks, hope it will not be a big different in gas mileage
