Actually these questions may be best responded to in the fueling section though and linked to here? If you've covered this in another thread please point it out.
Possibly, I get my oil pre-filtered to 10 microns and pre watered through a centrifuge 4 times. A guy uses it in his 525D and I buy the excess. I have tested the water content and it is very low if not 0. I have already tested the mixture and also kept it at very low temperatures to see if anything falls out and nothing. I think this is a form of diesel bug.
I had the bowl off today, the mixture is very sludgy, completely soft and doesnt appear to melt. Not actually grit or nything.
Duhhhhh.. my bad this is the Fueling forum. And I must apologize again.. reading your reply reminds me that I asked the above question in another thread somewhere a bit ago and my feeble brain forgot that you already answered.
So now what? Ask the fellow you get it from if he has had any issues lately? Maybe his supplier (or his own filtering etc.) is getting sloppy? Are you getting the excess from what left at the bottom of drum? 10micron is supprisingly big. This is what a typical Auto filter "nominal" rating. Not sure if small bowl filters are less or more. So what ever is plugging your stuff is larger than 10 micron. Yikes. Not an issue for diesel so much (it has a lower viscosity) but more of an issue for higher viscosity Veg. You might consider refiltering to 2 micron. Many many do that.
Have you put a jar of your recent batch of oil out to watch? Especially one with your 10% mix? You didn't mention do you use pure petrol for sure or is some alcohol in there (ethanol)? If your PH is High and you have some alcohol in their it might be creating some soap like stuff falling out.
What is your storage? How much air? Is your storage usually full or half full for example? How moist is your local climate? Oil is Hydroscopic and will absorb moisture from the air.
What do the walls of your storage vessel and your bike tank look like? Do you have a chicken skin like layer, thin brownish plastic-y looking layer on them?
You may know all about this stuff so let me know if you've covered your bases in these areas. I do not want to be insulting by encouraging you to climb a tree to trim it when you've already fell the bad branches.
