BIO AND THE PUMA

[Wortho]

Hi guys, anyone know if the Puma likes Bio, i know the Tdi likes it and the Td5 doesn't cause of the rubber shock cones in the injectors but i havn't heard anything about the Puma?

[dmdigital]

According to the owner's manual - No.

as far as i'm aware NO new engine likes BIO......the seals and stuff they use cant take it

well that's thinking ahead then isn't :angel:

Now where's that enviro-greeny friendly LR video i saw posted again :D

Ah but it is much more forward thinking by Landrover than the greenies, crops should be used for feeding people not cars.....................
The english have finally worked this out and are cutting back on biofuel production.

Any ideas on a blend maybe, say 50% bio.

Recycling fish and chip oil is pretty green isn't it?

The owners manual says max 5% blend.

Pity 'cause I have a Bio diesel servo just up the road

i wouldn't even attemp it

a guy brought his RR (i think it was a RR) into our local garage with all sorts of problems,

found out when he had been filling up with diesel that it was infact bio even though the garage never stated that clearly.

cost him thousands in repairs, as the bio had made all the seals with in the fuel system swell and i believe it did something else funky too but cant remember now.

no, its potentially bad carma in any modern common rail injected engine and its got nothing to do with the seals, Ive done several posts on the subject, If you have no joy on them hit me up and I'll have a go at doing it again for you.


to summate

If you get perfect bio all the time and run nothing else that might contaminate the system all good. IF you get contamination the bio doesnt have the head room in its specifications to deal with the potential results of the contamination.The end result is all bad.

well i stand corrected then but i was told when they pulled it apart the seals had swollen causing injectors to leak etc etc

[Blknight.aus]

yes but thats not the real damage, seals are cheap and easily replaceable... (ok maybe not the cushion seal in the injector but thats usually the last one to go)

most people get lucky and do seals before they do real damage..

its when your on your new biofriendly seals that you'll find out what can get seriously damgaged...

[discowhite]

gee! all this fuss for whats basically a dirty old ford motor!:twisted:
bet there's craploads of transits and 07's running on it in the uk...

cheers phil

i have ran 100% bio for the last 12 months clocking up 40 000ks in a 200 tdi with the fuel pump advanced and the turbo running 16psi and flogged the sh#* out of it more power no smoke and when i took the head off after drowning it in a river there was barely any soot in the cylinder head and the injectors look fine and the engine has done 320 000

[Outlaw]

That's promising to hear Defmec... though don't think a 200tdi would be considered a new engine :p good to know for my 300tdi though :D

yes we ran full old chip oil in ours too, but the 200tdi is neither a new engine let alone a common rail

[defmec]

sorry to be defensive dullbird i read your post to quick and missed the newww part:p

[Blknight.aus]

to desummate the previous summery of my post...

the killer is the injection pressure

the older the diesel (unless you get into unit injection like the TD5) the lower the pressure.

Biodiesel (and WVO) breaks down under extremes of heat and pressure and loses its lubricity (so does bad diesel)

if your injectors are pefectly clean then this isnt a problem but if you get any "crud" in the injectors (and Im talking crud with the dimensions of microns) then the loss of lubricity becomes a problem and the "crud" will deposit itself in the injector. Once it gets started it will attract more and more "crud" and eventually you get injector problems...

Higher pressure injectors have finer internal tolerances then lower pressure ones in an old school diesel like Fozzy the tolerances in the injectors are wide enough to do dounuts with road trains in and the pressure is low so for starters the fuel doesnt break down and any deposits wont clag the injector. In big reds modern common rails unit injected diesel youd be lucky to turn a monocycle and the pressures is up above the cracking pressure of the fuel so you'll get the deposits...

IMHO the TDI's and suzis are marginal but so long as your fuel is correctly filtered you should be laughing

IF I could get injectors for big red at $200 each ID run bio but at over $1100 each its not going to happen as you have to assume that if one injectors bad then they all are close to bad...
