the Brasil owned oil company Petrobras just released a new diesel fuel.

has a higher cetane index than the typical fuel here - 51 vs 42

it also consists of about 5% bio-diesel.

the owners manual for my 110 which has an International Brasilian made 300Tdi engine states not to use any bio-diesel fuel.

why do you think this is the case??

it is a 2003 engine.

thx,


Jaime

rover is playing CYA...bio is better then regular diesel for your engine as long as it meets the ASTM viscocity rating for the engines fuel requirement.

just wait...with all the issues that are going to come up with injector pumps on ULSD, auto makers are going to reccomend bio-D here pretty soon

dont fear the 5% you wont be able to tell the difference

``bio is so back-woods at this point??

Petrobras is like the Exxon-Mobile of Brasil. The stuff will be really good.

``dont fear the 5% you wont be able to tell the difference??

Thanks Musky, that was my thought also, yet, not really sure.

``The biodiesel can eat through normal rubber lines??

Pehaps you have bio-diesel confused with Enthenhol (however it is spelt) where yes, the alcohol will eat through rubber .

Pretty sure this is not the case with bio-diesel.

Is this correct???

Thx,

well VW states that it voids all waranties if you run more the 5% bio

I ran B100 all summer long and never had 1 issue and I have B20 in the tank now and it was 5* out yesterday morning:)

commercial biodiesel is everybit as reliable here as regular ULSD and has to be, If you were selling tankers full to fleets I think it would catch up with you pretty fast if what you were selling was sending trucks to the shop with problems.

just because you are not in the US dosent say your fuel is inferior...infact the US is behind the rest of the world when it comes to biodiesel.

If it were me I would look at the source, if its a major supplier in that market with established market share and a reputation at stake I'd trust them because they dont want to risk that reputation. Capitalism will very often protect you no matter where you are in the world.

Never heard that one, are you sure your not confusing Bio-Diesel with E85?

cool - thanks guys for the input.

as it is only 5%, the sulpher content still should be fairly high in the fuel which also is a concern for the pump lubrication.

I am going to give it a shot and see if there is any noticeable performance difference.

PT,

in all the years of vehicle ownership, this is the very first time I ever of heard of this!!

makes total sense though.

really good tip which I will pass on to other Defender owners here in Brasil.

Comes from many years of working on vehicles for which I couldn't find hardened valve seats. If you can't make the engine works with available fuel, make the fuel work with the available parts.

I don't know if it makes any difference, but the folks I've suggested it to are still driving high compression, mid 1950's powered vehicles. The 331 Hemi I rebuilt in 1982 has gone more than 100K miles with stock valve seats/valves. The owner puts a pint of two-stroke oil in every tank of fuel and the engine still shows great vacuum and compression.

I have run B100 on my 300tdi for a while now. I did change all the ruber fuel lines with SAE-30R9 lines to make sure that the bio did not eat through it.
Bio is a great solvent and will clean ou the muck that is in your tank and lines, so be ready to change the filter a lot when you first start running it. My fuel guage sender was not working properly before I ran Bio now it works prefectly...
At b20 concentrations you don;t have to worry about a thing with your motor. you could even run b100 for a whiel before you lines started weeping. It does lubricate better than ULSD, and can be added to ULSD.
Look for info on the web, A 300tdi is no different thatn any other diesel so use bio if you want. Plus it smells like a fryer.

thanks. it is only 5% here.

this is why I still wonder why it is printed in the manual not to use any bio-diesel.

the only answer I get from the folks here is the lubrication issue with the fuel pump.

I am going to use the suggestion of PT and run a tank to see if I can detect any difference.

Jesus Paul.....

Do NOT ADD OIL to your fuel. It can cause carbon buildup within the combustion chamber. It was OK with old diesel desgins, but not TDIs.

If you feel the need for additional lubricity get a quality diesel fuel conditioner or add some quality Biodiesel.
