Why did you got to 10w30? Our cars Mivec operates on oil pressure, and actually need the thinner 5w20 oil... Could be your problem... I ran 10W30 for a week once and the car ran horribly... Just a thought...

 

I just got my ralliart w 40k miles on it about a week ago and I realized after it warms up that the col light comes on if you let it idle for awhile. As soon as you give it a little gas it goes off. I checked the oil and my oil level is fine. I still have plenty of warranty left though so i'm gonna get to the bottom of it and have them fix it if they have to. I'll see if the oil change sticker says what oil viscocity they used.

Questions:

1. Will I be able to increase oil pressure a little by using a different oil viscocity?
