*Warning* WVO question! - Page 3 - PeachParts Mercedes-Benz Forum

FFF looks kind of pricey, $3K +install for a two tank? I can't swing that. Its 30% of what I paid for the car

More than I paid for my 124

I think it would take a long time to pay for itself. Maybe if I moved it car to car...

A very common problem with not leaving a stub is damaging the barb while removing the hard tubing and creating a permanent slow leak.

Not on my 87 300D it didnt. The OD of the clear hose is about .220". So, what you get is a 3/8 inner diameter hose going over a .220" outer diameter hose. We dont even need math to know that aint gonna work, esp pulling 14 in Hg.

Maybe my 87 300D is not the "norm". But there are no clear hoses associated with the whole dino thermostat housing. Those are all 5/16. And I just repl that from dealer, 5/16. 3/8 must be for 123 or something.

Use a clear inline filter and put it in front of your first D2 connection and then move it forward toward the IP as you confirm that the air is not coming in prior to that point. You'll have it narrowed down in 30 mins tops!

I know, I know. But the problem only recently surfaced, and only when engine coolant is around 100C. And if Im careful about feathering throttle once I push the purge button, I can keep it from stall. Once diesel prime is restored it runs fine.

The wife is about to pop out another kid (due today!) so it might be a while before I can tackle it. And we're not rolling the old benz to hospital...I'd never hear end of it from her family...

The eBay auction is long over, but the owner of GFS listed his Libby CRD, and stated it was on it's SECOND engine because he failed to change his engine oil at 3000 miles, and the first engine lost lubrication due to lube oil polymerization. That speaks volumes about the quality of the kit -- basically it doesn't heat the oil, and it gets washed past the rings without burning.

Personally I think it's stupid to run a modern common-rail engine on WVO, but if you are going to do it, do it knowing the consequences.

Only if you convert it and/or process oil incorrectly. The latter is just as true for BioD. Plenty of ppl running 100's of thousands of miles on WVO without issue. Follow simple rules and there wont be any problems. Whats stupid is continuing to fund the corrupt oil industry when viable domestic alternatives exist.

It's not a viable alternative. Do you have any idea of how much oil we actually use?

As of 2000, the United States was producing in excess of 2.9 billion gallons of waste vegetable oil annually, mainly from industrial deep fryers in potato processing plants, snack food factories and fast food restaurants. If all those 2.9 billion gallons could be collected and used to replace the energetically equivalent amount of petroleum, almost 1% of US oil consumption could be offset.

Oil consumption in passenger cars, commercial trucks, of what "universe" of consumption are we measuring to say 1 percent?

Also note that just because it couldn't be universalized for everyone doesn't mean it isn't a viable alternative for some. We're kinda at the point right now where we don't need a singular solution, but probably WVO could be one of many possible alternatives, do ya' think?

of having a second tank and all the associated plumbing and valves. I constantly read here about fuel and air leaks, valves sticking, lift pump problems, switchover delays etc. What I am hoping I can use is a single tank, that won't damage my engine on startup.

To stay on subject,

A few air leak problems don't begin to compare with IP or engine failure by running cold wvo in a cold engine.

Forced Induction has said many times, these engines were designed to run on #2 Dino diesel. All of the internal specs of the IP, injectors, engine internals... etc are designed to use that specific fuel with it's corresponding viscosity - lubricity and thermal characteristics.

That said, one has two choices, either convert the oil to be more like #2 by converting it into biodiesel OR changing the oil's characteristics by heating it to lower it's viscosity and bring the engine up to operating temp prior to injecting it.

It isn't magic. It's mechanics and physics. If your car is disposable to you then you MAY get several thousand miles on unheated wvo/one tank system. Or depending the condition of your IP and engine internals....... you may get to go car shopping sooner than you think.

That being said, I am more emotional about it than most. To me it IS about NOT contributing to big oil any longer than I have to. The hospital where I worked on 9/11 sent a disaster team to x-ray bits and pieces to determine identities. Two of my nephews are fighting in Iraq.

If I don't become the change I seek for our future, how can I expect others to change first!

Or blend with minimal mods and accept the gamble.

Where did you pull universalized out of that?

1% is an insignificant amount of fuel. If you want a truly viable alternative fuel, you need to look for 5%+ before the masses will start to take it seriously. Until then, it will only occupy the time of the fringe enthusiasts.

When developers start working with algae based crops, it will begin to open up the availability to the masses.

That's the kind of mentality that keeps Lovecraft in business and classic cars in the junkyard.

Yeah, I would add my voice to the "two tank is better" chorus. I kinda doubt that one tanking it would be less fuss in the short run. When I've blended, it has ended up cleaning out all kinds of crap from ye olde phyule system. You'll have to change filters and in doing so it isn't too hard to introduce an air leak anyway.
