Just to stir **** up again.

The last few weeks I have been trying premix in my '89 N/A. Here is what I 'think'

I got 38 more miles out of each of the two tanks that I have run.
The idle lowers a bit when I put in the premix.
The engine feels smoother at idle and at any RPMs.
The motor pulls way past 7k, almost to 8k
Of course there is a little smoke and the fumes are there but they were there b4. Can't give an honest assesment because I removed the Cats at the same time I started premixing.

I do know that, the tank that I didn't add oil to seemed much rougher. Maybe placebo.

 

there should be no smoke associated with premix.

how much are you using?

 

Not again! ;-)

I allways say 100:1 SonicRat will be more exsact and state 128:1

exscuse me if my math is wrong today but that would make it 1.15oz per gallon of fuel.
If you have "NO" OMP.

Glad to hear you had excelent results!

 

No real smoke, you can see......vapors????.......in headlights behind you at night. More like running rich than smoke

Also the OMP is still hooked up
