Blazer w a 6.2L diesel

Hi all. Im usually on here for my jeepster but am thinking on buying a blazer with a 6.2 liter diesel. I do not know much about this motor but would like some input if anybody has any.
Thanks
Matt

see my hood emblem. ive noticed quite a few 6.2s in blazers around here. though mine is running a 350 with TBI heads and carb intake everything else is stock but she runs very well with the carb feeding tbi heads.

The Diesel Page - for the 6.2L, 6.5L, and Duramax 6600 (6.6L) GM Chevrolet and GMC diesel engines.

The folks there and on the diesel forum on Colorado K5 - Full-Size GM 4x4 Restoration and Off Road Community can tell you quite a bit about them. They're good engines and will last a good long time getting great mpg if you take care of them.
That said they aren't and never will be a Cummins, Duramax, or Powerstroke. A lot of folks think they were supposed to be big power towing motors and they aren't. They were meant to be great mpg replacements for GM's most common engine in it's trucks in the early 90's...the small block V8. Similar levels of power as a factory carbed SBC while getting at least half again better gas mileage and sometimes double.

Just thought I'd echo this. I have a wheelin' buddy that's got a 6.2 diesel, and what you said is pretty much the truth.

Andrew has posted a good reply. If you take care of the engine: change the oil, put good fuel in it, and replace the glow plugs if they are bad, and keep the cooling system in good shape(hmm, sounds llike what you would do with any engine, except the low plugs) it will be a long lasting engine that is predictable, easy to maintain andreturns good fuel milage.

My 6.2 has 74,000 miles on it. It is in a 6700lb, 1990 suburban with 39.5' bias ply Iroks and a 1 ton drivetrain with 5.13 gears(it does have OD). I pull 15 miles per gallon consistantly. My big block powered truck that weighed a little more than the sub only got 7-9 mpg and most any small block in my truck would maybe get 12 mpg.

Botom line: If you want a good running engine that gives good mileage, the 6.2 is it.

I hope this still counts. Well, my brother had one and he said that really, it's a good engine. Gives you good mileage although it runs only for a short time. it's like it'll exhaust all that it can, give you the umph, but it'll quickly get tired.

Sounds like somebody who never took care of their diesel.

There's plenty of us with well over 100k on ours and they run just fine.
