I was watching the LiquiMoly product video online and saw the advert for speedtec which promises benefits for my car. Knowing its a trusted product made in germany, i decided to try this 'Speed tec' last month, it actually gave my car more pickup power than usual. I had fun throttling in traffic lights when it turns green, literally leaving behind other vehicles for a second. For those who love the traffic light dash-off, this product is good and recommended to use.

What I like
- Better throttle acceleration
- Less engine noise (actually never even know that the engine is on because too silent)
- Better than those fuel injector cleaners that says this and that and nothing significant

What I do not like
- After full tank fill up, fuel economy immediately starts to worsen
- BUT Will return to normal average fuel economy once the 'potion' run out.

Review
I've always been using fuel of Octane 95 grade, but once, I went for meet up with forum friends, and one of them offered some of his Liqui Moly Speed Tec Benzin. I noticed much smoother and prompt response from my engine, providing quick power delivery. From then on, I've used it even on normal local roads, and rides were much comfortable with smoother, quicker pickup power and throttling.

What I like
The ability to provide optimum performance even by using average grade fuel.

What I do not like
Most shops do not sell these. Thus finding it will take quite awhile.
