Volvo D12

Are you looking to add another truck or replace? I run a 05 D12 and yes they are good motors I love running mine but I would still prefer a N14 or S60 any day.

 

I wouldn't hesitate on buying one. Problem is they are starting to get into very high miles on them now days and they tend to be a throw away style truck and engine as it is not abnormal to see those engines with 1.4 1.6 million miles on them. By that time the truck itself is rotted and shot.

 

I own both a 05 Volvo Daycab D12 and 2011 Volvo 630 with Cummins ISX. The 05 D12 has 758000 on the ODO and uses 1 gallon of oil every 20000 miles. (Pretty sure it is from oil leaks) and I see 7 mpg during the summer running 80000 pounds one way and running empty coming back. That is in the hills too with the cruise on.

 

Last July, I picked up an early D12A (pre-2000) with under 700K original miles.

I get 8.2mpg at 65mph with 35K in the box up/down on I-81.

Had a cracked head (leaked diesel into crankcase <---- VERY RARE) and just got it fixed for $3500 OTD.

Every one I've run into claims they are very good motors (unlike D13's). Only time will tell.

 

I thought the D12 was discontinued about 2005 or 2006.
Many people I talked to back then said it got better fuel economy than the D13 did.

 

They were not used after 2007
