How are you aware what’s actually in these gasoline components at each auto elements retailer? Learn the protection knowledge sheet, often simply discovered on-line. Part 3 will checklist the product’s composition.

We took a deeper take a look at a well-liked gasoline therapy aimed on the fanatic market. The guarantees are too robust to disregard: elevated horsepower, extra torque, cleaner injectors and decreased emissions. A 16-ounce bottle, avenue value of about $11, is alleged to deal with one tank of fuel.

The SDS says that the product’s fundamental ingredient–listed to vary from two-thirds to three-quarters–is a mix of aliphatic and fragrant hydrocarbons C-2 to C-20. 

Sounds unique, proper? That’s simply gasoline, doubtless used as a solvent for the additive. Nothing particular in regards to the gasoline will assist deal with gasoline.

The gasoline additive underneath our digital microscope additionally incorporates 20 to 30% 3-Oxa-1-heptanol, one other exotic-sounding compound. A fast search of the listed CAS quantity–a selected code assigned to each chemical substance–reveals that it’s only a comparatively non-volatile, cheap solvent often known as butoxyethanol or butyl glycol. An 8-pound jug, roughly a gallon, retails for about $20.

The ultimate ingredient listed, comprising not more than 5% of our 16-ounce can: glycerides, combined decanoyl and octanoyl. Its CAS quantity rapidly reveals the composition in query: glycerides with fatty acid chains which can be utilized in many client merchandise, together with soaps and cosmetics. It’s doubtless used right here as an emulsifier that permits polar and non-polar chemical compounds to remain combined collectively. It additionally helps maintain grime suspended in answer.

So, some math says that the $11 gasoline additive incorporates about 20 cents value of gasoline and about 75 cents value of a typical industrial solvent. Then add lower than an oz of the emulsifier.
