You just have to run three tanks of the 93 pure gas to know.
Running pure gas vs a mix gives a few more BTU's per gallon.
There is no rocket science involved.
The 1992 454 (7.4L) in the motor home will make more HP and better MPG on 93 pure gas.
There seem to be no advantage to running it in the 2000 4.6L engine in the Towncar.
If after the 3rd tank of pure gas you do not see/feel do what YOU want to do.
It is about $0.70 a gallon more here. If it was only 33 cents I would only buy 93 pure gas for everything we have that runs on gas. Typically premium gas has more cleaners in it as well. At least that is the case with Shell gases.
Let us know what you think after three tanks of pure 93 gas.
There is no on on this board can answer your question in your case with validity.
While I agree you may see little to know difference in your case you will not know until you spend a few extra dollars to test it.
In our case we can run premium for about what it cost to add a can of Seafoam so premium cost is a wash if trying to clean up dirty injectors.
Pure gas will not contain water because it will stay in the tank in the ground because it can not mix with pure gas but water does blend in with the gas that contains ethanol.
