Default How long until methonal go bad?

I have some in my reservoir meth injection kit. It's been sitting for a couple months and I see that the cap on the reservoir is not a seal cap. How long until I have to exchange the methonal ?

If it was in a cool dark place during that time, you're fine

How are you storing it?

If it's in a drum you're fine almost indefinitely.

Storing it in car has it's own list of issues. Rubber lines will basically dissolve, methanol eats uncoated aluminum rather quickly and the seals in some injectors aren't designed for constant exposure to methanol and will cause injector failure.

It's common practice when storing/not driving a car for long periods of time to drain the entire fuel system of methanol and run the car on pump gas for a periodof time to ensure the methanol has been purged from the system or diluted until it doesn't pose a risk to fuel system

I'm using it as a injection only. It's just the Reservoir cap is not a seal cap and I wasn't sure if the left over meth store will go bad in a non seal container. I have the old snowperformance unit. Does all caps on the new meth injection kit now come with a seal cap or a vented cap?

You are still ok with the older fuel. Not as much alcohol as ethanol. It's not a venting cap IIRC

Well I'm assuming you dilute down from pure methanol using distilled water... that will in theory keep forever.
