OIL CHANGE?.HOW OFTEN?

[Gunzz]

I am now using Royal Purple Synthetic oil and plan on changing every 6,000 to 7500 miles, even though you can go longer with it. It is well worth the price difference, and evens out to be the same or less in cost, since you skip that in between oil change. PLUS you get the additional benefits of Royal Purple's technology. You can feel the difference in the smoothness of the engine right away.
