how much damage

ive been changing my own oil since new in 06 using 10w-30 thinking that it whould be better in the heat of north carolina. i just did a search and found that it calls for 5w-30 for reasons that i didnt know..... did i hurt my engine? its not doing anything abnormal that i can tell, just worried. thanks in advance

 

Not that big of a deal

 

fuggitaboudit....not a big deal.

 

Nothing to worry about. Your engine is not concerned.

You might've lost some gas mileage in the first 2 minutes of engine operation, but that's about the extent of the "damage".

 

good lookin out fellas

 

sell it before it blows up in your face

 

i know the question sounded dumb but durring the search chris 4x4 had a good post about the auto. vale timing or somthing like that....just making sure the next 1 will be the right stuff, however it just seems to thin.

 

The first number is for cold weather. If it's hot where you are, not much of an issue. They recommend 5W30 due to the variable valve timing being regulated by oil pressure. So if you use the wrong weight, the VVT will be off.

 

It ain't nothing...Here at work, THey put 15w40 diesel oil in everything. (and we ain't got any diesel trucks)

 

...a ton...

 

First number is viscosity at cold temps, second at hot temps. Once his rig got to operating temp, it's all 30weight oil, so meh.
