A fellow ka-Gulong Redditor u/digitalhydrogen asked last week about fuel additives. A fitting name to ask this question, I suppose.

Short answer would be: It’s not fully disclosed up to 15 years after fuel companies register it with DOE. You know - Trade Secrets under the Compendium of Energy 2018. So, additives under like Caltex Techron, Shell’s V-Power/Nitro+, etc are considered trade secrets which have passed DOE’s Technical Committee on Petroleum and Products Additives (TCPPA), Philippine National Standards (PNS on Petroleum, DENR, DOH, etc.

However, we have a few items listed as part of fuel formulation but not limited to octane enhancers:

Unleaded Gasoline includes Hydrocarbons (Alcohols C2 to C4, Aromatics, Benzene, Ethers) and Sulfur.

Automotive Diesel Fuel includes Sulfur and Cetane.

Industrial Diesel Fuel mostly just add Sulfur.

Question: Can we use over the counter additives like STP? Yes you can. The better question would be: Do you really need it during these times where engines get more efficient and fuel being generally cleaner after banning Lead? Well, not really or it’s really up to the vehicle’s owner. Which open this thread to information from other members of this sub-reddit.
