I'm sorry, what? All I see is this:

"This message is hidden because mrphotoman is on your ignore list."

Can you help me fix this? I can't see your posts!

In answer to Maxwell's question, the equation given from the link I gave is the following:

Toulene
R+M/2...114
Mixtures with 91 Octane Premium
10%...93.3 Octane
20%...95.6 Octane
30%...97.9 Octane

104 Octane
R+M/2...104
Mixtures with 91 Octane Premium
10%....92.3 Octane
20%....93.6 Octane
30%....94.9 Octane

This is assuming a 15 gallon tank.
