300sdl fuel tank
 

I have a 1987 300sdl.
Does anyone know if there's a bigger fuel tank for this model?
Any options?

Ahh........the vehicle already goes 600 miles on a tank. How much further do you need?

I'm getting around 450 on a tank. I would be very happy with 600.

Any suggestions as to what to check regarding my low number.

I'm new to the diesel world. new as in two weeks.

Highway driving helps.

Keeping the speed to 68 mph helps.

Keeping the tires at 35 psi helps.

Avoiding the brakes really helps (plan ahead and coast).

I believe PowerService helps but can't prove it.

Ignoring the fuel gauge when it first touches the "E" line also helps............there's another three gallons in there.

IF your gauge works "properly" :eek: I speak from experience; however, running out in the garage was just a coincidence.

hitting the highway next weekend.
Washington DC to Charleston SC (525 miles).
I'll check it out then.

Thanks guys

"hitting the highway next weekend.

Ditto on the 68. I have a problem keeping it under 75.:rolleyes: I useit as a daily driver (64 miles) back and forth straight highway 530 in the morning no traffic............

Seriously though before my cruise quit i did a week at 65 both ways and got 29.5 mpg on that tank:D

You didn't happen to fill it up when it was out.........??

I'd really like to know how much is usable.

$0.02
 

Carry 2 x 5 gallons jerry cans. They fit nicely on the 2 sides of the trunk. That will increase you range by approx 300 miles. I get on average 900+ miles if I do that. Even if a bigger fuel tank is available, I really cannot see the justification to spend the money and labor to change out the old one.

87 300SDL
 

70 - 75 mph, an easy 600 miles per tank. At 80 - 85 for 35% of the time and 70 - 80 for 65% of the time, the mileage drops to about 500 per tank. Tires at 33-34 psi.

I really, really want an SDL. As much or more than I want a 190D. The significant other says I need to get rid of at least one of the current crop before I can get another vehicle. In my defense, one of the non-runners planted in the yard isn't mine, I'm just holding on to it for a buddy....
