any info on this..ive been searching on how to properly mix the meth to water concentration..when i seen people running 50/50 or 70/30 meth to water, are you guys basing this off by Volume or Weight. anybody got a sure-fire way to mix

[ttbmer]

A lot of info abt this if u google it. From different forums too, With that said the easiest way for me is volume. I believe almost everyone here does it by volume too.

This is what I do

50/50 mix by weight:
1 gal mix = 55oz water and 73oz meth

Volume.....this is not rocket surgery

[chrisw335i]

lol..im just making sure...rather be safe than sorry and i cant help to make everything scientific..its the perfectionist in me!

VoCo + VaCa - VdCd = VfCf

Vo = Volume original
Co = Concentration original

a = add

d = drain

f = final

This formula allows you to add/drain at different concentrations and know what the final concentration will be.

Your supposed to do it by weight....

I've always done it by volume but seeing this post means that my 50/50 mix by volume actually contains a much lower meth concentration. Perhaps I'll start using weight too!

[garfi]

So, for 50/50 mix.
If we fill half of 1gal. can with methanol and the other half of 1 gal. can. with pure water. It will be wrong... ?

[chrisw335i]

yeah from what i gathered through google searching prior to starting this post was by weight is correct..and by weight its a little more confusing how to calculate the proper mixture..by volume is obviously the easier method. I was mainly looking for someone to chime in with a formula or calculator they might have to get a by weight mixture...one that is user friendly and not over-complicated for the majority of us here to use!

Here's a great chart you can use...shows you what to do while volume mixing telling you what meth% you've got back calculated for weight..

[chrisw335i]

yes..this is exactly what i was referring to..thanks!

Good find Dz,

I still estimate it, probably add a little more meth than water. To me it's not an exact science since meth testing shows very little power/cooler difference between 50/50 and 70/30. Guys who run 90/10 are just wasting the methanol.

[Skydive]

That's handy.

Thanks.

so according to the chart, if you had to eye it, 40% water and 60% meth should be pretty close for a 50/50 mix by weight in a gallon container?

[MrHeavyFoot]

So for the last round of testing by Shiv and others where a 50-50 mix was not flammable... was that by volume?

Would a 50-50 mix by weight be flammable?

[R1000K3]

The difference in concentration by measuring weight or volume is negligible. Use the method you prefer and stick to it to keep conditions the same.

A 50/50 mixture by volume (and also by weight) will burn if heated. It is no near as flammable as stronger mixtures though.

You also don't have to be super accurate. 48/52 will do just fine as well

I am sure that mixing by volume is close enough........

But.

Water weighs more than meth, so if you mix 50/50 by sight you will be getting more water than meth in the mix.

Water is actually 25% heavier than meth.

Meth weighs 8lbs per Cdn gallon

Water weighs 10lbs per Cdn gallon

I gallon = 4.546 litres.

But that chart is pretty handy for eyeballing.

This is over complicated?
50/50 mix by weight:
1 gal mix = 55oz water and 73oz meth

Or if you want a formula: 55ozW + 73ozM = 1Gal 50/50 WMmix


No reason to estimate or eyeball or any of that.
1) Take a gallon jug like left over from window washer fluid. Take it into your kitchen and pour in 55oz water and mark the line with a sharpie and label "Water"

2) Pour in another 73 oz or dump it out and pour in 1 gal. Mark the line with "Meth".

3) To use in the garage: Pour in distilled water to first line, pour in meth to second line. Done. Same mixture every time.

I add in a few drops of food coloring so I can see it in the tank and in the lines.

Yep... There was a LOT of misinformation and confusion about this when I first started out. After some research and math, i found out there's a pretty big difference between the two, and volume is NOT close enough, it's a pretty big diff actually.
