All I can say is that I have used Techron for decades with very good results. However, I have recently bought a twenty year old Van (for 800 bucks
) and the vehicle has had some hesitation and problems at startup. I first ran Techron and 87 oct gas and had no real difference. Then I ran another techron and 91 oct and had a very slight improvement. My third tank I tried MMO thanks to getting a MMO shot for free from Kragen, and there was an immediate difference. 4th tank I added a larger dose of MMO and I am getting no problems at startup, and much less hesitation and it runs smoother/quiter. I am also running ARX with a good dino for general cleaning and an engine rattle. It also seams as if the rattle is none existant now too, maybe a litfer that was helped by MMO? Anyhow, I don't know the science but I know that 2.99 for 32oz beats Techron in price and clearly it beats techron in the results I was looking for. Any Techron fans want to weigh in, because I'm thinking of putting Techron down for MMO.
