But some say you need to use additional lubricants to protect interior surfaces of the fuel tank and lines.

Oh and toluene is often used to bring up bad oil to 87/89/91 octane levels.

... Toluene is 103 AKI. AKI, is what the US standard is for gas. (What you see on the pump)

So using that info, your calculation is a bit off...
And in CA you can't buy Toluene actually (just saw the OP is in CA)

I used to use Toluene a LOT back in the day, so I've done all the calculations and figures... I HAD an excel sheet too, but I recently deleted it because it's just not worth the cost...

And about the need to add lubricants, you don't need to add any if you use Toluene, but you'd need to use something like Marvel Mystery Oil if you used Xylene
