2008 Mitsubishi Eclipse GS 2dr Spyder Auto
My car's owner's manual calls for 5W20 oil. My dealer said 10W30 is fine. What do you think? Thank you.
I'm sorry but I'm confused. I assume the automotive engineers who work for the manufacturer which in this case is Mitsubishi are the ones who come up with the weight of oil required. So do you think they would also say it doesn't matter whether it's 5W20 or 10W30or might they say if it was either we would have said so. Thank you.
