Question on Biodiesel

Glen can't specifically say how it effects that particular engine but it appears many of the current high tech diesels don't like it at all. Our fleet of diesel work vehicles are now fitted with stickers not to use Biodiesel as it could cause engine failure. I know 1st hand the latest F250's just stop completely.

I've been using commercially produced BIO (B100) from Marrickville in my 99 5L for about 12 mths without any obvious effects. having said that, I don't know what it's doing internally to the fuel pump, injectors etc. I am still prepared to use it even though the pump price is only 10c les s than Diesel. Take into account about 50klm less to the tank and a small drop in performance, it probably works out about even.

If you can get quality at the right price then I can't "see" any problems.

There's some very interesting stuff on the i-net about diesel substitute addatives .. evidently you can add other oils directly to the tank mixing it with diesel, with no apreciable performace loss, or damage to the engine. Main problem seems to be viscosity of the oils. it can start to solidify in the tank and lines, requiring heaters to be installed on tank and fuel pump. Haven't done it yet, still Googling the subject.
I'd like to hear from anyone who is adding old cooking oil, or whatever to their tank.

As for bio-diesel, seems manufacturers are leery of it. Most new fourbies have 'Don't Use' stickers on the fuel filler. Also, seems it's very expensive to produce at home, and to make useable quantities you'd be at it full time.

Thanks for the replies.

Dave, your right, at it's current price guessament.

But up until the recent price hikes it was at least 20c pl cheaper making it still viable. I haven't used a lot of fuel lately so I haven't been past to fill up, so I'm unsure of the price today.

The most expensive part of bio making at home is the methanol. If you buy a 200 litre drum it works out to less than 30c a litre. My mate has the latest model Hi Lux 3 litre running on 100% homemade bio and has done since about two months old. No problems so far after about 20 months. Getting the vegetable oil is the hard part, old animal oil is easy to get. The mixture I remember is about 60 animal to 40 veg oil plus the other bits. Washing and drying the bio takes all the time.

Greetings , i have been making my own bio for 2 years now - Works a treat in my Nissan 4.2 TDI 2000 model - on average it costs me .20 - .30 c per l to make ( as apposed to buying at 1.80+ a litre for dino )
Its becoming really hard to find a good source of constant oil -- I have used Lard - vegetable - sesame

lard works great - but a summer time fuel - sesame oil would be my choice


you will make mistakes at first -- so make little batches - then progress up -- i make 200 litre batches at a time


**WARNING** Methanol is very dangerous -- METHOXIDE is very dangerous ( mixed Methanol and caustic ) Be very aware of static electricity when working with your brew - work is a VERY well ventilated area and iff possible - have your main mixing vessel sealed

if you want more info - just let me know

P.s - 90 % of the time - the only negative recommendations are from people that know someone that had a friend that used it once ..... and hearsay is a fair more dangerous tool than a gun
