Biodiesel & SVO in cold weather?

From the back by the tank. It has 275,000 mi on it.

Then the problem is from age, road debris/salt/mag chloride and lack of preventive maintenance.

That tube is 23 years old, I'm amazed it (and many others) last as long as it does. Rubber naturally gets old and brittle, that hose should have been changed a decade ago. ULSD had nothing to do with its failure.

mb911, if you haven't changed all rubber (fuel lines, washers etc) that comes in contact with diesel to new ones, or preferably ones made of Vitron, you shouldn't go B100. Once you've done this, AND changed all the fuel filters to fresh ones, you could slowly step up the percentage, from 10% the first time, by 10% for each full tank you fill.

This being so because biodiesel is a, or works as a, solvant on rubber material and all the soot and shit that has been built into the walls of your engine. Because of this, your newly changed fuel filters will soon clog, so always keep a spair couple and nessesary tools (a screwdriver) in your car.
But to be on the sertain side, you should double check my info on how fast you can rase that percentage on a biodiesel forum.

But remember, 20% will do enourmous differances for the biodegradability of your petroleum diesel. Even 10% will do that and you don't need to do fuck all with your existing lines, if they are in normal condition. If they're not, you need to change them every once in a while anyways..

Sad thing is that a lot of the biodiesel produced today is of the "dirty" kind, a lot of it in the US is. With dirty means that it's total production line causes more, or close to it, CO than regular class 1 diesel. But check which places sells clean biodiesel at a specific forum for it.

SVO/WVO is better than biodiesel as it doesn't have any chemicals mixed in it to make it less viscuose. I know WVO people aren't too excited about biodiesel. Why and what the benefits are, you should ask them. I know Greasecar has a big forum, also check Frybrid.

It is leaking from the rear near the tank. I can see some residue on the bottom of the exhaust.

Oops, sorry for repost.

I was thinking of SVO more because I can get it cheap. What would be some pros and cons of it?

[rockwool]

The pros are that you don't have to filter it, settle it for a few days before you can use it, no slobbing while collecting or fixing it at home, no chance of it ruining your engine (with time) because of sloppy filtration/bad choice of source.

The cons are more abstract, as it won't affect your daily life and probabaly not your holliday eather, and is more on a philosophical level as you are still exploiting the land instead of using up a waste product, yes it's a renewable source but if we want this place not to go to hell just because of our generation (and a few before and after) we have to start using all waste products that we can.

Another thing is the signal you partly give when you purchase a product of nature, as SVO is closly related to biodiesel in that sence, is by saying to landowners around the world that they should cut our lungs out and feed it to us as food. We try to do good but we're still part of the problem. Another problem, but still a problem.

Finaly, SVO usage is contributing to is to increase malnutrition and starvation in this world. People in third world countries have already noticed the increased prices of agricultural products in their countries because of the increased demand of it that has come from the north. A demand that actually is increasing fast as this ethanol/biodiesel thing is pretty new and yet only a small percentage of our car fleet can use it.

We're all creatures of comfort, we all love to run the easiest way (even if the're other ways that are only marginally more troublesome) and we all have trouble understanding situations that we haven't lived our selves. I'm glad that I can't afford a nice rust free example of a diesel W123 yet (they're practicly non existent i Sweden due to stupid and unfair non diesel friendly laws) as I would have to do the same choises you're facing now.

Try Red Line web site is Red Line Oil

also this web site Red Line Oil: Fuel Additives

We used it for 27 years . it works

Where does it leak? i've run a merc diesel on kerosene with no problem..
