<font color=purple> I have a weird question about oil weight .......... I just did an oil change on our 2000 Stratus and they recommend using 5w30 but all I had was 10w30 because that's all I've ever used in cars that say to use 5w30. Am I wrong in what I've been doing ? What are the pros and cons ? I used to own a Pontiac Sunbird and when I used 5w30 it would leak but not with 10w30 ........ I know the difference of the thickness but what else is there ? Another question on the subject ............ would changing oil weight improve gas mileage ? I've never thought of it before and I thought I'd ask. I never had problems running the 10w30 in the Sunbird at all and the car ran like a top .........any thoughts ??? L8r, .
