Methyl Hydrate Warning

Reading time: 190 words. 1 to 2 minutes

Methyl Hydrate, also known as gas line antifreeze (similar to wood alcohol), added regularly to fuel tanks is an excellent way to prevent condensation from freezing and clogging gas lines on vehicles in winter. Truckers and equipment operators use it as an air dryer for air brakes.

You can buy them in small, 1 ounce containers but they’re expensive in small sizes for the little you get. I buy it in gallon jugs that last several winters. I keep a small container in my vehicle and refill it from the gallon jug I keep at home.


Warning: the plastic jug sprung a leak after several years. I suspect the plastic jug was never intended for long term storage and the fluid corroded the plastic. This is dangerous because Methyl Hydrate is very flammable; after all it’s used in alcohol fuel stoves and fondue pots.

In future, I’ll store it in glass containers after about a year or so. All it would have taken is one spark … so beware.

Update: different grades of gas have different levels of ethanol. Premium should have none or very little. Mid-grade up to 5% and regular gas can have between 5% to 10%.

Conclusion: you don’t need Methyl Hydrate if you use regular or mid-grade gas but you still need it for premium gas.

I have a bit of financial experience having invested in stocks in the 1960s & 70s, commodities in the 80s & commercial real estate in the 90s (I sold in 2005.) I'm back in stocks. I am appalled at our rapidly deteriorating global condition so I've written articles for family, friends & colleagues since 2007; warning them and doing my best to explain what's happening, what we can expect in the future and what you can do to prepare and mitigate the worst of the economic, social, political and nuclear fallout. As a public service in 2010 I decided to create a blog accessible to a larger number of people because I believe that knowledge not shared is wasted.
