I started using MMO in my small engine fuel. Once I have the engine sorted out and have run a few tanks of fuel dosed with MMO through an engine, it starts easier and I no longer have to tear down the carb to clean out varnish. I have used it on occasion in my cars and have noticed a bit nore pep, but no improvement in MPG
I completely concur as far as carburetors and requiring no maintenance when tc-w3 is used.
I've been using a tc-w3 and either toluene/xylene/acetone mixed in everything I own that burns fuel for years now. A couple years ago I took our fuel invoices for the month and added them up,I then started adding my fankenbrew mix at various ratios,each ratio getting a month in service then again adding up my bills.
I found 6 ounces tc-w3 and a quart of acetone per 100 litres of fuel reduced my monthly fuel consumption pretty significantly.
The air compressors will last 6 hours on a tank of fuel pretty consistently,with the fankenbrew I could get over 7 hours on a tank.
Now multiply that by 12 compressors.
On months where hours worked were very close I took a real close look at fuel consumption before and after implementing adding a fuel treat and I saw differences of over 100 litres less purchased even though hours worked were very close(within 20).
So that's 125 bucks saved for an investment of less than 6 bucks per 100 litres.
I also found that the machines weren't needing any servicing,which whenever there was a significant temp change they ran roughly,but not anymore.
And no fuel leaks from the carbs anymore either.
These machines get the living heck beat out of them daily. No one cares about my tools,they start em,let em run all day,the only time they are off is to fill them with gas.
Add that to the fact they are getting bounced around in the backs of trucks to and from different sites and I'm astonished they last as long as they do.
The last year or so I've also begun using mos2 every second oil change. I've found an even greater fuel savings adding it to the oil,and in the winter they turn over much easier and the men barely ever snap a pull start cord ever now.
So I'm a believer. I didn't find that overdosing does cause a consumption increase,and any more than a quart of acetone to 100 litres fuel doesn't realize a larger fuel savings,so the ratios I've posted are after testing in my own OPE over a period of 4 months.
As far as mmo goes its only in the last few months its been available here I use it in a top end oiler and I'm happy with it thus far in the mustang I'm using it in.
Just my experience,others may have different experiences.
