Calculating a premixed dilutant of VG 70% / PG 30%?

Hi There,

So I am new the world of DIY - been vaping for years.

So - I have a 1lt bottle of 70/30% VG/PG dilutant and I want to make this recipe:

Am I right in saying I cannot calculate the dilutant the way it is on there? As it is a premixed dilutant?
The nicotine is correct, I have a bottle of 7.2% in VG.

In which case, how would I calculate this to get it as close to the 70/30% (and hopefully keep at 4mg nic)?

Thanks! And BTW, great community - can’t wait to advance and hopefully join in making some great recipes soon.

Enter these values in the Calculator and your desire nic content in the green box.

This should work by the info you have provided.


Hi Pro_Vape

Thanks for the info - so taking in to account what you have put, it shouldn’t matter that I have a pre-mixed VG/PG dilutant?

So for example, the recipe calls for 3.87g PG & 26.49 VG - which means that I would just add 30.36g (26.49 + 3.87) of my pre-mixed solution?

Wouldn’t this mean that because my flavours are PG based and I have 12%, that the total PG will go up by 12%? (So it would end up being a 58/42 VG/PG mix?

I don’t mind this too much, but if there was a way to get it to stay 70/30 without applying rocket science - then I would prefer that!!


For some. reason I didn’t take the flavors into consideration. I just thought you wanted see how to enter the premixed base. Sorry if I screwed things up.

Any added pg would be in addition to your 30% pg premix since you can’t reduce that amount from your base.

Your premix is 7.2% which is 72 mg/ml not 7.2mg (unless i am reading wrong)

Do not vape 72mg/ml nic it will make you very very sick.

Jic that is what you were going to do.

No I realise that!

Maybe I wasn’t clear - I have a 500ml bottle of 7.2% Nicotine in VG and I also have a 1 Litre bottle of flavourless 70/30 VG/PG base (with no nicotine in it)

So I was just doubting my maths about maintaining a 70/30 VG/PG after I add my nic solution and my flavours. It doesn’t look like it will be possible as the ratios are wrong.

But I have a doubt, as if I have a pre-mixed base as above - doesn’t that mean I should use the “Max VG” option? I know it isn’t max but surely the total grams of the PG and VG in the recipe won’t be the same volume if I totalled those and used that amount of my pre-mixed base? (Sorry if this is a confusing statement!)

I have a recipe I’m gonna try out (a rise clone I found and adapted to 120ml):

So in my recipe if my maths checks out -
Starting with a 70/30

  • I then add 5.56% of Nictine in VG which means 5.56% added to VG, so now it will be = 75/25 VG/PG
  • I then add 17% of PG-based flavour, so that = 58/42 VG/PG in the end.

Is that correct? And if so, will that make that much of a difference to flavour compared to the 70/30 I got?

Thanks in advance, I appreciate your help

In my tired state yes i think the maths check out and no it will not make a huge difference to the flavour (it will make some it will likely be stronger) you will notice a difference in the throat hit.


In which case I shall give it a go!

My last thing I am unsure about is the issue with selecting “Max VG” on the calculator or not. Or just combining the weights of the PG + VG?

i would just select max vg
