I've had no problems with running on the magensol treated fuel, though I have to add that even though the rest of this batch has settled for over a month it still exhibits the strange foaming up when violently pumped. I've elected to pump out to 25l drums and stand in the sun for a while since that seems to help them for reasons I don't understand.
It may be that something contaminated the source oil (a detergent of some kind?) which isn't removed by the biodiesel process.
At any rate, I don't think I'll use magnesol again - although it might help accelerate normal batch settle times it messes up how I handle dregs:
Normally I settle each batch in a plastic drum for a couple of weeks. I have three of these drums in rotation. Before I use the fuel, the oldest setting drum gets pumped out into 25l drums via a 1u filter. These sit for at least a few days, then when they go into the car I leave the last bit at the bottom of the 25l drum. These dregs normally gets thrown into the youngest settling drum so nothing is wasted.
When a settling drum is exhausted I pour the dregs from that into the youngest settling drum too. All the dregs go around and around and no bio gets wasted.
The trouble is, add magnesol into this mix and this ends up spread throughout the whole system which I can't say I'm keen on!
The foamy batch it definitely settled to the bottom of the settle drum in a white layer, but I don't want to pour those dregs into the youngest batch that's settling.
