Gumout Multi System, Seafoam, and STP

[DarthDuty]

The 3 cans on the newly redone additive asile of my walmart:

Seafoam: $6.97
SDS dated 3/1/2015
Flash Point of 55°F

STP Multipurpose: $6.47
MSDS Dated 2/16/12
40-60% Petroleum Naptha
Proprietary Mineral Oil
Flash point of 165°F

Gumout Multi System: $6.47
MSDS Dated 9/25/13
30-50% Petroleum Distillate
30-50% Naptha
1-20% Proprietary Fuel Additive (PEA)
1-20% IPA
Flash Point not listed

Whats best for oil? Whats best in gas? These 3 are crazy similar, gumouts video on seafoam making smoke due to the pale oil and its higher price. STP's no alcohol approach, and the PEA in gumout...

What are you trying to accomplish? I wouldn't put any of these in oil.

PEA is supposed to be a decent cleaner for the fuel system, so I'd use the Gumout out of the three, although I usually opt for Red Line SI-1 or Techron.

Gumout for fuel system treatment.

As far as the engine is concerned, as mentioned, what are you trying to accomplish?

You forgot about Lucas, Royal Purple and Techron cleaners available at Walmart. Since RP is the most expensive, it must be the best!
