This is one of the best sites I have found that has good information on oil. For all of you that have been wondering how and when to change your oil, please read so you can have a better understanding of the importance of the oil quality and interval.

And yes oil quality does vary, a lot.

 

good find

 

good one..someone should make that a sticky

 

Yeah I like it because it has good info and it doesn't appear to be pushing any specific product or brand.

 

That site is pretty informative. I now understand tires as well. They also have a section on suspension and another on brakes. Bookmarked! Good find!

 

good post man.
