have any of you guys used this stuff i have heard its just like regular petrolum based diesel minus the bad earth stuff and that you wouldn't even know the differance and i just wanted to check with someone who used it before i risked it in my baby?
thanks for the input

 

I'm running on anything from 0-100% bio for some 160 000 kms- roughly 100 k miles. (RME to be precise) So far so good- only the engine is smoother and doesn't rattle so much. And about 5-8% higher consumption on mixtures above 90% bio. Wouldn't want to use 100% if it's much below freezing though. Keep a spare fuel filter at hand, this stuff can dislodge lots of grime from your tank. Good thing about it is that it's the cheapest cetane improver you'll find and lubrication is also very good.

Fill up with my first tank of B20 2 days ago. So far I like it. Mileage seems about the same. Motor and VP44 are quiter. Only drawback at this time is the cost.

 

Hehe, now I've got an advantage- Bio is cheaper than regular #2 over here

At 3.45 US$/gal you need something cheaper

If the bio is RME it has about 8-10% less BTUs per volume than No2. In low concentrations some of this is offset by the higher cetane number letting your engine run more efficiently

alpine,
you want to break down what you just said in honky english for me! haahaha

Bio is easier to ignite by compression ( higher cetane number) than the dino stuff. But it contains less energy per gallon. In most diesel engines a blend of 20% bio and 80% dino will burn a bit more efficient. So you'll need the same or less fuel, even though there isn't that much energy in it (about 2% less for 20% bio).
Biodiesel is a strong solvent too- wipe stains from your paint as soon as possible. It can also clean your fuel tank and lines from old stuff that has settled there for the last xx thousand miles. So have a new fuel filter handy, it could get plugged up with the dirt that's already in your fuel system. (Any good fuel system cleaner has the same effect, but most people with plugged filters say that the bio was dirty)

so bio has alot of advantages i think i will have to get some of that!

 

136,K bio blend is all I have have ever run. No problems.

 

so this stuff is a good system cleaner right why hasn;t this stuff made it to the main street pump yet? and are they developing a lubricating oil. because if it is a lubricating fuel then wouldn't it be real easy to develop a motor oil thats based on the same product.

 

They won't make an engine oil out of it- but over here we do use rapeseed oil as the base for chainsaw oils, hydraulic fluids for forrest machines. Other vegetable oils are used for 2stroke oil base and 4-cycle and diesel engine oils are made mainly of dino.
Biodiesel has been quite widely available over here for the last 10 years. Most older tests showed that some of the fuel lines and gaskets weren't resisting the stuff and got eaten away. It didn't get sold at the street pumps for that reason, but was delivered to fleet operators. Actually pricing is one of the main problems with the bio stuff. Even at our extremely high fuel prices bio is still not too competitive.
