Anyone ever hear of dumping methyl hydrate to thin out the fuel before you go for an e-test?



We use methyl hydrate at work to unfreeze air systems in our trucks, and it turns out 90% of the methyl hydrate is the same **** as gas line antifreeze.



A mechanic at work told me for my 40 litre tank, dump in 2 litres of methyl hydrate and it should bring emissions down far enough to pass..



Who else has heard of this?

Ive heard of similar things, like rubbing alcohol in the tank.

There's a simpler, legal way to pass emissions, and I'm going to implement it.



Edit: Some day. LOL

ive never had a problem passing, if you're not ported have a good tps, main cat air pump, and working acv, the emissions numbers will be almost 0.



my 12a hadd 22ppm hc at idle, and 0 everywhere else

Methyl hydrate is alcohol based or something the mechanic said.. https://www.nopistons.com/forums/pub...IR#>/dunno.gif



I was curious if you guys had heard of the methyl hydrate trick.



And this is for my stupid daytona. I gave her a tune up and she still runs a tad rich, so I was thinking of trying this "trick" until I can solve the problem. I need plates on this badboy and they won't let me plate it until I pass..

Acetone LOL?

methyl hydrate is another term for wood alcohol, methanol, methyl hydroxide.

Sweet. Well I'ma try it.

We have been over my car with a fine toothed comb after the rebuild and it would not pass in Texas.



I had to take the Bonez Hi flow cats off and put stock cats on then it passed. We checked everything thoroughly and can't figure why it won't pass. It comes up for inspection again in March and I don't know what I am going to do then.



I have all the emissions crap still on the car. Air pump, ACV, EGR Valve, Good TPS. ECU shows no problems. All the solenoids are in working order. No vacuum leaks.



The only thing I can think of now is maybe it is just an O2 sensor going bad. Is there a way to test the O2 sensor? Maybe with a volt or ohm meter?
