Jeeps Gas or Diesel that is todays question. Both will have their advantages and disadvantages , it is really a question of what will suit you best in doing what you want your Jeep to do, how well do you want it to do it, and what is the advantage as far as running costs are concerned.
To find out the Motor Trend Dirt Every Day guys got 3 Jeeps and fitted them out the same, including a set of decent wheels and tires fit for the job in hand. As you will see. One had a 4 cylinder Cummins diesel transplant, the second one had the well know 4L straight 6, and the 3rd a Chevy V8 with auto transmission, this being quite a popular transplant. The fuel tanks were filled to the top and away they went for a day of fun driving on the highway, back roads, rugged rock driving and of course mud glorious mud. In an earlier post I showed a video of this same diesel Jeep driving totally underwater, and an earlier one again of the original gas powered Willys Jeep during WWII being prepared for and driving under water. Very interesting.
Many motorists are anti-diesel which is a pity as the modern diesel is nothing like what it used to be. Long gone is the smelly, noisy, billowing black sooty smoke beast of years gone by. In fact with many diesels today unless you are standing beside them with the motor idling you may not even realize it is a diesel. When it comes to getting through the real rough stuff nothing beats a diesel. By using the low range first gear with the motor at idle or slightly above, the high torque of a diesel will keep on keeping the Jeep moving, whereas a gas powered engine would need higher revs which could create wheel spin, to keep the motor from stalling.
The guys know a steel sump pan is better than alloy or a composite one in the rough.
Thank you to Motor Trend Dirt Every Day, most entertaining. Photos are video screen shots.
