I put 10W30 in a car that takes 5w30. one week later check engine light is on. is it related to oil viscosity?

Totally unrelated.





The 10W and the 5W of these ratings is how heavy the oil is during the winter. The viscosity is not enough to make very much of a difference, especially if the weather is above freezing when you start your car.





Bring your car to any of the major auto parts stores. Many of them will connect a scan tool to the diagnostic port and extract the trouble code. They will usually do this for free. This may help you to decide what, if anything, needs to be done next.I put 10W30 in a car that takes 5w30. one week later check engine light is on. is it related to oil viscosity?
not that's no related to the oil grade but check the level of the oil maybe you need more oil and that is the problem with the check engine light is on but check the level firs before you add more oilI put 10W30 in a car that takes 5w30. one week later check engine light is on. is it related to oil viscosity?
I've never heard of the wrong oil viscosity throw a code. 10W30 is used for higher temperatures than 5W30, but it really doesn't matter. Most likely your check engine light is on for something completely different.
that should,nt have anything to do with that. check the oil sending unit, you might have the wire off or it could be bad.
I would seriously doubt it.
I highly doubt it. I'd recommend 10w-30 in any vehicle that isn't going to be seeing snow.
NO
