Your Sig indicates you have an 8
1; do you own more than one?

That's pretty incredible. Nobody else with an LD28 has seen that kind of mileage.
. . . I regularly round trip 600 miles on a tank.
Now, that's not so unusual. With the L3N71b (no OD) and a smaller tank than the Sedans, my '82 Wagon can go a maximum of about ~470 miles if the tank is brimmed. I had a nozzle malfunction at a fuelling station two weeks ago, and fuel was running all over the pavement before someone noticed and shut it off (this was a Shell station). So it was definitely
full and I drove it about 480 mi. but it was very near real empty by that time. The Sedans, as noted, carry more fuel than the Wagons. And your '8
1 has overdrive, because it's MT. (Gen1 diesel Wagons were never offered with MT, at least in the US.)
But 40 MPG? Hmmm.
Mixing a little vegi oil into this new LSD diesel will improve its lubricity . . .
Can you take a few minutes and find me a link to a non-anecdotal source for this? Biodiesel, yes, it has much more lubricity (at operating temps) than LSD and ULSD. But VO? I'm really interested if it's been tested.
and your fuel mileage, I run about 20% svo to get best fuel mileage.
VO has less BTUs per unit volume than petrodiesel. Many folks have noted reduced fuel economy when running VO or BD, over PD. This is leaving aside
VO's other issues. I am not a fan, just to state my bias up front.
