Stop wasting your time trying to defend yourself and hire a good lawyer. They are worth the money...22 citations...no convictions here.

Ozzy, I'd have to agree with Jerry. Get a good laywer, and in addition get a good fuzz buster. I'm waiting to see a Duramax powered police pursuit vehicle. The only time it would be funny is when there is a high speed chase with a sports car and they get run down by an oil burner.

#483 of 490 Bad mileage on a 2005 by boomd Jul 02, 2009 (8:50 pm)
For some reason I am getting crap for mileage on this 05 silverado 2500.......1500 to the gallon. My last 2500 (an 04) I had, I was getting on the hiway anywhere from 22 to 28! I have bought both used, and I don't know if the 04 was chipped or not, but she was a runner. Any suggestions for the 05. Econ shows 15.5 at 1800 rpm's on the hiway.   Thanks folks,   Boomer Replies to this message: jbull454GMC (Jul 03, 2009 1:10 pm) jerrydock (Jul 05, 2009 3:41 am) boomd (Jul 05, 2009 8:06 pm) boomd (Jul 05, 2009 8:00 pm)

Replying to: boomd (Jul 02, 2009 8:50 pm) How many miles are on the truck? It may have an injector or turbo problem. Most likely if anything injectors. Replies to this message: jerrydock (Jul 05, 2009 3:41 am) boomd (Jul 05, 2009 8:06 pm) boomd (Jul 05, 2009 8:00 pm)

Replying to: jbull454GMC (Jul 03, 2009 1:10 pm) You have to take a systematic approach to this.   First comes attention to the drivetrain.   Get high quality filters for the engine, fuel, air and transmission.   Replace all your filters.   Use synthetic oil. I like either Rotella or Amzoil.   Add a bottle of fuel additive to the fuel. I like Lucas; but I am sure there are others that work well.   Now check yout mileage...carefully. I like to do at least 4 tansk in different conditions to get a baseline.   Still nto better?   I would suspect the tires.   I can't begin to tell you what a huge diffference tires can make on a vehicle.   Still no good? You might jsut have a truck that is not going to get good mileage.   I don't know why this happens, but some are just better than others. Replies to this message: boomd (Jul 05, 2009 8:06 pm)

Replying to: jbull454GMC (Jul 03, 2009 1:10 pm) It seems to run very smooth to have an injector problem. Since we bought it I have started to put additives to the fuel.
