C13 motor
David T. Richelderfer:
2004 Beaver Marquis Sapphire - 6 to 6.5 mpg would be an improvement over our C-12, 505 hp engine, but we are usually pushing 48,500 lbs around - the coach at 42,000 lbs plus the toad at 6,500 lbs. We have averaged approximately 5.25 mpg over 45,000 miles of driving, which includes diesel usage by the 12.5 kW generator. We don't use the big generator all that much because the toad carries a gasoline Honda 3000w that is usually used unless we are running the coach's A/Cs while traveling in hot weather. The Honda generator will run for 16+ hours on a 3.6-gallon fill of gasoline.
Fred Cook:
Thanks guys for your replies. The motor has a prefix of LEE. So, I guess it must be a regen or an ARD. The coach is beautiful with four slides, and our current coach with the C 12 only has two slides. I am a little worried that the ARD head would be a bad decision.

We have the 07 C13. It is currently in at CAT for head work. Ours is not the regen going by the serial number. I do thing ours is a left over 2006. Still the CAT guy took one look and knew. I understand from talking to the mechanic here that there is now a fix.
Fred Cook:
Just curious… is it illegal to delete the emissions stuff off the C13?
Scott Shearer:
Fred,
Yes, it is a federal violation of The Clean Air Act (likely a state violation too) to remove or disable any pollution control device on your Cat engine.
The non-regen ACERT used a catalytic muffler (DOC), so technically, replacing the muffler with a non-catalytic muffler would be a violation. California owners are experiencing this with their new inspection regulations.
Here’s an old Caterpillar YouTube video ‘showcasing’ the pre-regen ACERT technology (there are other videos out there).

Keith,
What’s going on with your C13? What kind of head work are they having to do?
