Keep the pump running longer. Higher temperatures speed the reaction. Lower temperatures take longer. Run that puppy overnight and you will be fine. You could also do the 3/27 test on it every once in a while to see when it is done.

Wait, you said four gallons. Shake it longer. I assume you are shaking it instead of using a pump.

You could also draw a really hot bath and put the jug in the hot bath to heat up the mixture. Good chance you will be sucking methanol fumes as they escape from the jug. Better to just shake it longer.

okay

I have been sleep deprived and realized what I did after. I shook it a long time.

do I need to heat it up to boil off the methanol before I put it in the car?

Hmm--Sounds like you havent made BioDiesel before....?

MUCH more to making GOOD fuel than just mixing up veg, caustic and methanol in a bucket!
Check out this UK site--It explains everything you NEED to know.

Nah--IF its done Properly those VOC's are recovered back to liquid and re-used in the next batch!--Thats the way I do it.....
--I agree though, the vapourisation and venting to atmosphere of methanol fumes is both dangerous and foolhardy as well as being allegedly hard on the environment....

All the details of how to recover the excess meth etc are on that website I quoted...

WVO

"Why would anybody ever bother with Romanian" The Thomas Crown Affair

I made biodiesel 14 years ago. I have been running Straight Veg Oil since. I use to use a paint stirring attachment on the end of an electric drill. In an 8ish gallon metal bucket. If you are really trying to make biodiesel cheaply just to see if you can do it. You probably have the drill and paint stick around the house. Turns out making good biodiesel is expensive. And time consuming. Just my .02 cents.

Expensive...?

Guess thats relative!

With Diesel here in UK at approximately $9.00 per Imp Gallon I think not!

I can make an Imp Gallon of Good BioDiesel for approx $2.50 a significant saving I'm sure you'll agree.....

Time-consuming? Guess I spend around 2 hours total hands-on time, and say three days from oil to BioDiesel to complete a batch of 180 litres....
--Which will last me a three weeks to a month.....

Depends on how you are set up. I certainly wouldnt recommend mixing a flammable hot fluid with an electric drill!--Recipe for a fire big-time!

Flammable

In the US I can not see making biodiesel when it is so easy to just run straight veg oil.

The electric drill is off to the side and the flammable this is another reason I do not make biodiesel.

I wish I could make biodiesel then I would start on bio and switch to svo then flush with bio it would really save money. I started to make a bioprocessor. But I needed the pump to move grease for filtering. And all of the parts were expensive and hard to put together just right. And I had a lot of parts already. Sad part is I have a 55 gallon drum of methanol on the other side of my house double wrapped in plastic for 2 years now. Someone gave it to me because they were tired of collecting and making biodiesel.

Shaking a 4 gallon bucket of cold veg sounds like a bad way to make biodiesel.

Every forum has the 2 sided debate of why would you make biodiesel vs why would you convert a car to svo.

This may just be my background or the area where I live, but what are your sources of vegetable oil?

I might soon have a place to store up to 500 gallons of WVO, but where do I get it?
The bldg is big enough to set up a bio-diesel processing contraption, too.

No wonder w123 diesels are so cheap on eBay UK and with so few miles.....I wish I could export one.....

The diesel may be high over there, but the good thing is that most of the smaller diesel vehicles get 50+ a gal....

Import

Actually the laws have changed and you can import cars if they are more than 25 years old much easier than it use to be.

And there's me looking at the American Rust-Free cars, thinking wouldnt it be great to grab one of those!--That pick-and-pull thread lead me to see many rust-free W123 bodies over there--neglected, shabby and forlorn yes--But rust-free....
--Wear, caused by poor repairs deferred maintenance and interstellar meilage and mechanical issues is Much easier than dealing with UK Corrosion issues deep in a W123 chassis!

I would pick a rust-free body over any/all mechanical problems every time!

Yup--We got loads of cockroach bodied high MPG Diesel cars here--But they are all Horrible--modern plastic crap--You can have 'em all!
