Re: MMO and/or ATF in fuel

I know a lot of guys in the packard community run 10% diesel mixed with gas to help with vapor lock issues and it for sure has worked for many. once i put the phen spacer and correct factory heat shields in place, i had no vapor lock issues so never tried the diesel. That being said, i see no reason why then that adding MMO or atf wouldn't change the boiling point slightly. I'd wonder how well it stayed mixed, only time would tell.
