Bio or fossil diesel

If the bio is from a reputable source and of good quality without any 'additives' then it should be ok.
Given that some oil companies run biodiesel plants so that they can add bio to their product to replace the lubricity lost by the removal of sulphur the increased wear might be a furphy.
I have noted the same as you with good B100 the engine runs smoother, runs cooler and is cleaner exhaust wise with very slight loss of power and for me no change in consumption.
But I have run bio from several Volume Plus outlets and it is of poor quality, causes very high EGT's, big loss of power and increased consumption. After these experiences I will never buy VP diesel again.
I would suspect that the worn pumps being displayed are after bio has been used and it has removed all the dino varnish and gunk which has increased tolerances and caused problems with the pump, therefore the bio is the problem, not!!

I havn't run B100 since late last year as I moved and cannot get it now. I still run B20 from Gull however. My car still runs better today than it did before I started using Biodisel. So far I've done at least 50,000kms running either B100 or B20 and it blows no smoke while driving and runs as good as gold. Before biodisel it was a typcial smokey surf, now you'd never even know it was a diesel except for a puff of smoke when it starts. I can only speak from my experience but mine has been nothing but positive. I didn't even need to replace my fuel filter the whole time I was using it.

I have found most diesel mechanics know nothing about Biodiesel except the war stories from people who have had bad biodiesel - from a backyard operator mostly.

Ask them, and they will also have lots of other war stories from people who had bad dino diesel but somehow think that is irrelevant.

There is no way of attributing pump issues to Biodiesel unless one takes a brand new diesel pump and runs it that way.

I have been running it mostly - whenever I can, for more than 130k's and know that my 1HZ runs smoother, cleaner and quieter than it used to - even when forced to run dino diesel. Starts quicker too.

I buy fuel from SAFF and know that you can expect them to stand behind their product if there is clarity that it caused a problem other than cleaning out the sediments in your system from years of dino diesel use.

I buy it from SAFF Boronia when in Melbourne and find them to be great guys (it is independently owned).

I make my own biodiesel - summer time i run it at 100% bio -- colder months maybe 50/50 (dino/bio)

I know what goes into my bio - and i know how well i 'wash' the diesel so i have not had any issues

In general - you run cleaner , motor runs smoother and quieter - MOST new parts fitters will tell you that bio is something to avoid , and thats based on hearsay and not from personal experience

I believe that Rudolf diesel first used coal injection + compressed air to run his prototype motor - later on then used coconut oils to run his motors and not this wonderfully refined stuff at the pumps today-

I have been running bio in my nissan patrol now for over a year - and have had no issue at all ...... but as i mentioned earlier in the post , i make my own so i know what has happened in the production process and i know i have washed out excessive caustic / methanol from the BD
