Biodiesel oil changes

Biodiesel cleans the gums from your tank and fuel lines, I would expect gums to be carbonised in the engine so wouldn't expect a big difference to the oil.

I personally wouldn't extend oil changes on a diesel at all, but that's just my choice.

All I have read about biodiesel would indicate your fuel lines will be fine.

G'day

Extension of oil change intervals could be done or not done based on oil sampling.

>>> An oil change costs around the same as a tank of fuel

Your oil change costs $100+? What the bleep oil are you using?

Strewth don't start me on oil prices... My Jack has to use a synthetic oil as that seems to be the only oil I can find with a 5 weight ie 5w-30.... Just bought a new 20 litre drum of the stuff at $190... enough for not quite 3 changes...
Repco had a 25% off sale over Easter & I thought there was plenty of Oil in my drum, imagine my horror when the Castrol man hit me with that price. I've tried it on semi synthetic 10w-40 and it works well untill the temperature drops and then it just won't start....Also I have to buy genuine filters but they are reasonable at $26 trade but if the dealer does a simple oil change I have no change from $350....I think the last time I had a dealer do this I was hit $96 for the filter...The change interval is 10,000 km though so I guess I just have to put up with it, great tow vehicle otherwise...
Anyway back on topic... Bio diesel has these cleansing properties which I would imagine to be a good thing does this mean that one may not need to use any anti algie additives?

I wonder if one of those fitchy things would improve things???

Barnsey,
I have been following the biodiesel forum for a while now, I have used 3 tanks of 100 so far in my GQ. Mine is a 1994 model. So far, fuel filter is still spotless but i carry a spare in car just incase it clogs up.

As for your fuel lines, in theory, you should replace them as most manufacturers started using different hose compositions around 1994. So i would say yours will eventually stuff up. So just change them and save yourself the hassle of one breaking down while your driving.

Some of the administrators in the biodiesel site have been using biodiesel for years, mostly home brewed back then but now most of them buy it in bulk lots between them and share it around depending on how much each member orders. Some of them have also increased their oil changes from 5000 to 10,000 kms without any problems at all. Infact, a few have stated that their engine oil is much cleaner now that they run biodiesel 100.

I can only tell you what i have expierenced with mine, I changed my engine oil 2 weeks ago, It was my first oil change since using 100 biodiesel. The new oil has done approximately 800 kms to date and it is still showing a gold colour on my dipstick. I mention this because as you well know, most diesels would show black oil at the dipstick after a few kms. So from my expierence so far, its all good.
And NO..i wont be changing oil every 10,000 kms just yet. I want to use a few more tanks before i decide to go that path, but im just and lod fart and i like to take precautions, after all...tis GQ is my pride and joy and i intend on keeping it for a long time yet.

I hope this helps mate

These bypass filters look good. Companies claim they get 100-200 000km without an oil change! I will have a better look at these filters to make a decision but they appear good. Even if the oil is changed every 50 000km then they it would pay for itself very quickly.

Does anybody know where in SA i can get more info on them?
