    ATF in fuel tank ?

    I know. But the 6.5 was also made by GM and the injection system was made by Stanadyne. They have run millions of test miles @ the proving grounds and test fleets as well as thousands of hours in the labs. I would say that they know what is best for their equipment whether it's under warranty or...

    ATF in fuel tank ?

    I don't know about other diesel manufacturers, but GM, Stanadyne & Bosch ALL say NOT to use any gasoline, engine oil, ATF, or 2-cycle oil in the diesel fuel for their engines & injection systems; they are NOT approved as additives for diesel fuel. They claim that they are detrimental to the...

    Oil analysis concerns

    I would still check for air leaks somewhere in the system.

    Oil analysis concerns

    Your engine may be getting a dose of unfiltered air. Check your air cleaner assembly and the rest of the induction system for possible air leaks. The intake resonator (the black part that sits on top of the engine and says 6.6 Turbo Diesel) has been known to develop cracks. These cracks are...

    Batteries, batteries batteries

    I can only speak for GM vehicles. As far back as I have been able to find out, at least over the last 50 to 60+ years, GM has not made any production 24-volt systems for civilian consumption. Our batteries are wired in parallel. Many military vehicles DO have 24 volt systems, though.

    Batteries, batteries batteries

    Thanks for the information about batteries. However, I don't mean any disrespect, but our diesel trucks do NOT have 24 volt systems. They are 12 volt system. The two 12 volt batteries are wired in parallel in order to maximize the amperage available during starting, especially in cold weather.

    Whats so great about a skid steer?

    I would say that their advantage would be maneuverability. A skid steer can turn around on its own axis. I haven't seen many regular tractors that can do that very easily.

    Batteries, batteries batteries

    I have heard good things about Optima batteries, but I've never had one, so I can't comment from personal experience. My only personal experience has been with OEM batteries, generally Delco, since 95% of my vehicle have been GM, and Sears DieHard. Delco batteries are kind of a crap shoot...

    Calibrate your fuel gauge?

    Exactly! ________________ The fuel gauge on these trucks only gives you an approximation of how much fuel you have remaining in the tank. It is NOT very accurate. Looking at the design of the sending unit, it really can't be any more accurate than it already is unless the sending unit was...

    Max. Speed in 4wd?

    I have driven in 4-Hi at 70-75 with no adverse effect other than worse fuel economy. My truck doesn't have Auto-4WD. I had Auto-4WD in my '02 Trailblazer and I did NOT like it at all. The truck drives in 2WD until the wheel speed sensor senses that the rear wheels have lost traction and then...

    NOSTALGIA: How bad was the GM 350 diesel?

    The early Oldsmobile 5.7L V8 Diesel engine was rated at 120 hp on cars and 125 hp on the pickup trucks. From the 1980 model year thru 1985 it was rated at 105 hp. (It hardly had enough power to drag itself around) http://en.wikipedia.org/wiki/Oldsmobile_V8_engine#LF9_Diesel The 1979 4.3L V8...

    NOSTALGIA: How bad was the GM 350 diesel?

    The biggest problem is that a Celebrity is a front wheel drive unibody car and the engine is mounted transversely. If you were to cobble it into a K2500, it would have to be FWD only and that engine in that truck would hardly have enough power to pull itself over a 1 inch pebble. :D

    NOSTALGIA: How bad was the GM 350 diesel?

    The 4.3L (260c.i.) V8 (LF7) was available ONLY during the 1979 Model Year and ONLY in the mid-size rear-wheel-drive Cutlass/Malibu/Century, etc. The 4.3L V6 was available in the rear-wheel-drive midsize cars (1982 - 1984) as well as the FWD Midsize cars (1982 - 1985).
