Default Re: Testing methanol purity ?

Not really.

We bought a drum of methanol to mix 20% with normal SUL petrol and were running that for a bit last year. However after 2 sets of injectors failures....concerns were raised.
And these injectors are supposed to be methanol safe

When this mix is poured into a jar, almost immediately it separates very visibly

Another car I work on is running the same, and did all last year. Same methanol type, same source, same type of drum. But not the same drum. This car ran faultlessly, and still does.

Both drums were brand new and sealed from same supplier.

Checking this car over for racing this year, we poured some of their fuel into a jar. Even after quite some time, no separation was noticed.

Now the car that ran faultlessly was also using different injectors, so that aspect might be unrelated.

Both drums were medical grade pure methanol from the same chemical supplier.

So something has to be up with one of them. Ive another drum here Ive had for years, still havent got around to mixing some petrol with it though.

But it does bring into question...when we use methanol...how do we know how much methanol is really in it ?
