What do you think about MMT octane boosters? In particular, what about the reddish-brown deposits they leave behind?
Most of us already know that when the bottle says “increases octane 7 points” they mean going from 91 to 91.7.
I did some searches on this board and the net, and there is not much out there. One thing was clear: do not use MMT in any greater concentrations than the manufacturer’s recommendations.
Here is a good article: http://www.europeancarweb.com/tech/0503ec_octane_boosters_tested/index.html
This article is pretty positive. Their tests show considerable octane boosts.
And some basics: http://en.wikipedia.org/wiki/Methylcyclopentadienyl_Manganese_Tricarbonyl
When I use a bottle in my car, I can feel a noticeable difference. The car is smoother and has more pep. Throttle response seems better. It actually feels a bit better than when I mix in 4 gallons or so of 100 octane race gas. And a single bottle of MMT costs about the same, or even less, than one gallon of race gas (last time I got some race gas I paid $7.99/gallon).
But I am concerned about the deposits that MMT leaves behind. Are they cumulative? Will they keep building on top of each other, or will some equilibrium be reached? Will an Italian tune-up, a can of Techron, or water injection, remove them?
I’m also concerned about my rings. Each time a cylinder fires, some deposits will land on the pistons tops and the combustion chamber, where they will accumulate. But some deposits will land on the cylinder walls. The rings will scrape the cylinder walls clean, but will this act like sand paper on my rings? The effect would be small, but over thousands of miles, it could add up.
I have a bottle of “Prestone 0-60 Octane booster” and it says that it is safe to use in every tank. Not that I want to do that, but is it really that safe?
I know even less about the Ferosene octane boosters (see the article above). Do they leave deposits too?
