<p>[QUOTE=&quot;Pete475, post: 11425935, member: 310812&quot;]Good Morning all. 2 questions that I have been researching on the interweb and can&#039;t get a definitive answer on. Maybe you can shed some light.&nbsp; </p><p>Background C15 Acert bumped up to 550 Hp. 1820 on the TQ with 98k on out of frame rebuild. </p><p><br /></p><p>1. I run Rotella oil.&nbsp; I do my oil changes at 20k. Up to 10k on the oil change I use no oil. After that I use somewhere about a gallon every 1000 miles. Has anyone eles have this problem? What&#039;s the oil for a C15?</p><p><br /></p><p>2. When I&#039;m running down the road at 71 mph my fuel pressure is between 85 and 90 PSI. What is the standard fuel pressure for this motor?[/QUOTE]</p><p><br /></p>
