Bio fuel is vague because we have bio diesel and Ethenol for gassers, so I don't think so.
If there is a bio diesel car, then yes it can take regular diesel.

Same for a pure Ethenol car, however an engine set up to run pure Ethenol switchs to gasoline, it will run richer than normal because ethanol isn't as energy dense as gasoline. So you need more of it to get the same power.

When it comes to bio diesel I know nothing about it.

If by Biofuel you mean the flex fuel cars, then no, they are meant to run on ethanol and ethanol blends, not diesel

Please elaborate, which biofuel, which car, which engine system?

Like many things, the answer is "it depends."

Bio diesel and veggie oil are two different things. Bio diesel being an industrial highly refined commercial product and veggie oil being well, as raw and unrefined as it gets.

The poster of the add doesn't know what he's talking about if he said it's converted to take bio diesel.
There's no need to modify a diesel in anyway shape or form to take bio diesel.

His misinformation is bio diesel = veggie oil.

You can ran straight diesel in it too, you'll just have a larger fuel capacity.
Personally i'd take it off because it's an eye sore, but I'd keep it for the apocalypse or if fuel prices ever skyrocket again.

I wouldn't give over 6 or $700 if that for that car unless it drove really will. Paint, suspension, interior, brakes one most other systems will need work before it begins to be reliable and comfortable.

Not trying to be rude to OP but I agree with you.

Here is a 420sel in area for $1,900 for comparison.

I REALLY want to and can buy it but, I need something dead reliable and cheap atm.

I would buy that car if I were you. I feel you've had a bad taste for older cars. If they were taken care of and maintained, unlike your 300SDL, they re usually reliable. Age doesn't make a difference. I've had a lot of luck with old Benzes. I think I'm at 15 or so Benzes older than 02. Half of them were projects (I buy them that way out of choice) but the clean ones on initial purchase never let me down. After a diff replacement on my current daily, I've driven it to Georgia and back with no issues.

The gas engined cars from the 80s aren't as dead simple as the diesels. The chassis has all the same issues as the SDL does because it is the same chassis. The vacuum system and the spaghetti that's all under the airflow meter can turn into a nightmare if someone who didn't know what they were doing has ever been in there. Without records of RECENT work done and decent history showing the car was maintained, the V8's can easily be bigger money pits than his SDL. If even considering dropping $2K on a V8, think more logically and drop that money on a used engine/drivetrain for the SDL, at least it already has a lot of stuff done to it that the "new" car will likely need too.

Don't fall for the "cheap Honda" routine either. If you do, you'll likely wind up with a Civic from '96-'04 which have HORRIBLE automatic transmissions. If you go for one from that era, go for a 5-speed, the slushboxes are absolute garbage with an extreme failure rate.

If you want something dead reliable, find something Japanese with a 5-speed and learn to drive it. You'll get good economy, good reliability, and a decent ride. When you're done with it, you can probably sell it on for what you paid for it.

Wow... to quote Luke skywalker... “what a piece of junk”

Yes, the car should be able to operate on diesel... a properly converted veg oil car should be started on diesel fuel, until coolant warms to operating temp, and only switched over after that point... and shut down after switching back to diesel fuel ...

Since no engine pics are listed, bet the “conversion” consists of a heater and a diesel tank... expect the main tank to be gummed up...

Ad says the car has a veggie oil system. Yeah, it'll burn diesel just fine. I'd turn off the heater to the diesel tank and lines and such.

(Rest of this post is opinion, YMMV, this is not legal advice, please consult with your personal physician before engaging in _______ activity, worth what you paid for it, etc.)

Veggie oil systems are kinda like a tattoo or facial piercings on a pretty girl - not an upgrade under any circumstances. A perfect implementation of either being "not a huge downgrade" and very easily going to "what a flaming disaster, wtf did you do to your car(body)?"

That said, in Texas, someone may get away with an imperfect implementation of a veggie oil system without immediate disaster, and at the miles on that car you should expect to be doing injectors and most of the other stuff that would be fubar'd by a bad veggie oil system anyway.

I would definitely pay less for a car with a veggie oil system than one without one. Again, it is not an upgrade.

Having looked at a couple of "veggie" vehicles in the past, I'd say that assuming they're any different in Texas is a poor assumption. Every one of the ones I saw had injection problems and blowby issues. Hard to say which came first, but if veg oil has been run through it, it's scrap to me. My opinion obviously, but it's a strong one.
