| Any good or bad too stay away from? Have a Cummins and get along great with it, but seen a few trucks lately that I might like that have Cat engines. |

|
Northeast CO | What year, model of cat? |
|
| |
|
Mount Vernon, WA | Stay away from anything built by Cat 2004 and later. Pre-2004 is OK. JMHO |
|
| |
|
| This is in a 2002 Pete. Says 350hp. Does not say what cat engine it is. |
|
| |
|
Between Omaha and Des Moines, 7 miles South of I80 | Probably a CAT C-10 or C-12 engine; at that lower HP setting |
|
| |
|
central Ia. | C-13 I would guess, don't know much about them, we have 2 C-15 motors one is an 03 single turbo, the other is an 06 twin turbo both have been pretty trouble free other than usual wear and tear. |
|
| |
|
Between Omaha and Des Moines, 7 miles South of I80 | C13 didn't come out until roughly 2003. |

ecil | C 13s are the worst truck motors I have ever ran . They can only get about 6 mpg. I had 5 of them running at one time and they all needed overhauled at about 500.000 miles . That's why they typically sell so cheap . |

Near-north Ontario, French River | I'd kill for 6mpg. I've had 3406B Cats and n14 Cummins and struggle to get 5mpg. Our higher payload (140k) probably factors in somewhat but from talking to most guys doing heavy work it seems like the average around here 4.5-5 . |

Dearfield Co. | they made a fleet E model that was a multi torque engine.IT was rated at 355 horse.But my guess is its a c-10 or 12.And as far as staying away from any cat after 04 I disagree with that --------there are tons of 15 liter accerts running around that had lite tweaking that do good |
|
| |
|
| No more Cat engines here.
The C 13 I drive is terrible on fuel. |
|
| |
|
Northern CA | A 3406E might have been the best truck engine ever. The C15 pre-emission was good too |
|
| |
|
South Western Ontario, Canada | I agree with Fawazhay. That's what's on my Western star. 1996 with 435HP
Sorry Thud. 7.8mpg dragging btrains from tillsonburg to greenfield chatham.
Most of the 855ci Cummins are very good engines too. Good power and fuel economy.
Although we have a 2006 kenworth with C-15 accert and she is a royal pig. 4.7mpg doing the same run with the same trailers.
Emissions crap in the 04 to basically 10 are junk in my opinion. Now fuel economy and power are back I'm impressed with the newer engines using DEF.

Dearfield Co. | the E models wernt perfect by any means--------to start with they were prone to oil leaks and then cat wouldnt cover it so the leak surfaces got covered with epoxy.Then there was the oil consumption issues.Then that was followed with head gasket issues and then along came the broken crankshaft fun time.I had one that came apart every 30000 miles for something.Cat offered a crate engine to replace it the last time it went and they put in a later serial numbered E model that was slightly better and this one broke the crank about 280000 miles..So the truck got sent away.the accerts had their issues but the C-15 accerts can be made to get fuel mileage as well as run like they are on fire

Wi | I wouldn't be afraid of an ACERT motor. The C13 seems to be hit or miss. We have one in an 07 T600and it gets around 6mpg pulling milk tankers at 72mph with hills(7-9% grades) and plenty of starts and stops. Our 01 Freightshaker with a 470 Detroit gets a little poorer economy but that could partially be attributed to the 4.11 rearends versus the T600s 3.36's. I wouldn't say the C13 is terrible to drive. Ours is set at 430hp and I prefer driving it over the 470 Detroit. I like the low end torque. There is a 500hp calibration for the C13 as well that you can get your hands on outside the dealership.
C15s are better but they get a pretty penny. Many people compare a C15 ACERT to an N14 and say the ACERT is junk. Well when you actually compare apples to apples, the C15 doesnt look so bad. Both it and the EPA04 ISX Cummins have some issues. The ISX loves EGR valves and turbos. C15 has no variable turbos and no EGR, thats the point of ACERT. ACERT is based on the Miller cycle versus the Otto cycle which is why they have the twin chargers, make ridiculous boost and have Variable intake valves. |
