re: PSA: Home Depot has Trufuel 50:1 on sale today only

Naphtha is a very broad term. Alkylated naphtha, which is up to 70% of the product per the SDS, is not a run of the mill cut. Its the product of light ends reforming and is usually blended into gasoline to boost octane without adding volatiles. That’s what makes this stuff what it is, a stable fuel that just happens to be more expensive to produce. If you say the final mixture has a heat value lower than average gas then I’ll take your word for it, but that would be surprising as the entire reason refineries go to the trouble of making it is to boost octane. In fact I would suspect the balance solvents are there just to dilute the octane number.

Regardless, the target user of this stuff is never going to know the difference, someone squeezing an extra 10% of power out of their small engine is mixing their own because they’re burning a lot. Of course it’s never a bad idea to drain the fuel system but again the target user of this stuff forgets, and in my personal experience with a simple top off it runs as well as new and has never gummed up a carb. If you had to pick one to leave sitting in the tank for three months in the winter trufuel is definitely going to cause fewer issues over regular mixed gas.
