I have tried to answer you based on my understanding, for anything else you have the contacts.

But still, questions do come up.
* Why is usage measured in terms of time - 1st two weeks, then the next 2, and then the regular usage levels ?
> I could top up my tank and then use only half the tank in the first two weeks. Since the initial 2 weeks have elapsed, should I move to the lowered levels of additive ?

• Initially they are suggesting a higher concentration, less liters of fuel and higher pill strength so that the initial deposit cleanup is taken care and effects are seen faster.
• Other additives suggest that effect can be seen only after 1-2 tankful only. You can follow that method too, just add 1 pill for 60 liters.

• No its not based on time but fuel amount, 1 pill for 60 liters. Check the initial link and my above response.

• Direct selling, their model is similar to Amway.

• I have yet to see that statement from any one of them wherein they even claim anything in numbers except that they clean up. Here also gains will vary based on driving conditions and engine type. I agree with you, 35% can be seen as an upper limit.

• No, is it available in India ??.
