A guy approach me at the kapak this morning, trying to sell me OCTANE TABLET

Thought you guys might be interested to know.
Sales pitch: Specifically designed with nano technology. Involved in NASA space shuttle research & development. Space craft carrying limited amount of highly flamable fuel, OCTANE is the booster energy for those fuel to help in terms of save petrol & increase horse power. Space craft need to be light weight & therefor save fuel I important to ensure the shuttle gave enough fuel to return to earth with limited fuel. Space shuttle exist since 70's, why now only introduced? We have the answer for that. 1 of the scientist left the R&D, came up with his own idea to help save petrol for road vehicle. OCTANE TABLET has developed with slightly toned down performance to avoid road vehicle being burst into flame. Ever since, millions of our satisfied customer has been benefited from Dr.Space Shuttle. And now, OCTANE TABLET is very affordable RM8/pc, 4 pcs / pack. Before refill petrol, throw in a tablet then fill up full tank. You can have the rocket power provided save petrol up to 25%. Abang imaginekan, 10 ringgit petrol only can do 50km, now you can do 63km. If 1 full tank 50 ringgit, you can go extra 63km! Jimat RM12.50! Bagus kan? Hari ini saja, 1 paket RM32. Abang nampak hensem kacak, saya kasi diskaun lagi, RM30. Hari ini saja, lain talak. Hari ini saja.

My opinion: space shuttle uses high density liquid oxigen as fuel, where got petrol? Octane main function is to retard the burning point, doesn't increase horse power. Octane is liquid. If tablet, it need some sort of hardening chemical, can my engine digest those chemical? If not, will it be blown out directly through exhaust valve or become carbon stick in the combustion chamber? Even if it does get out from engine, it will definitely jammed at the catcon!
Ladies & gentlemen, make a smart decision please.
