The car has 215k on it. Always changed oil every 5k. However i have blowby. Car runs good in every way. Just wondering if i could put a heavier oil in it- I always did that for older cars. however autozone says you have to be careful because it can mess up the timing in newer cars. Not sure a 2007 is considered a newer car. The car uses 5w30 oil. I want to put in 10w30 oil. Also I dd something stupid I put in 8 ounces of Marvel mystery oil in thinking maybe i had some gummed up valves or rings. It is now spitting oil out the oil cap. OOPS before it wasnt. Another reason for using heavier oil. I think the heavier oil affects cars with variable valve timing. Not sure if this car has that.
