私の中ではヒット商品です
RED LINE を愛用しています。段々値段が上がっている様ですが、梅雨時とか、エンジンのふけが悪い時に使用します。 初回は満タン時に1本、以降は満タン時にチョットづつ入れています。私にはかなり効果があり、愛車も23万kmになり、調子も最高です。

Good value for a trusted product
There are a lot of fuel system cleaners out there, but I know Red Line from my amateur racing connections, where their products are highly respected. I bought it for preventive maintenance. My car runs fine, and I want it so stay running fine. The bottle directions say to use only half a bottle after the first use to maintain a clean system, which tells me they are not trying to sell more product, and that it is probably pretty strong. I've just run it through one tank of gas, and saw no issues with drivability while using it. I will use it again next year to keep my system in tip condition.

給油メーターも正常になった
満タンにしても動かなかったメーターの針が復活。また、低速時息継ぎするような感じがほぼなくなった。

中古車購入後に
中古車購入後に入れてます。まずV-Power満タンとこれ1本を入れ、回転数高めを維持して運転して燃料を使い切ったらオイル交換をして、その後は適量をガソリンに混ぜ続けています。状態が悪い車にこれを入れると落ちたカーボン等が(燃える部分もありますが)オイルに落ちるので、汚れを抱きかかえられるオイルとこまめなオイル交換が必要になりますね。逆にある程度汚れが落ちきったら予備整備的な量でいいので、50Lの給油であれば1/7程度の投入で済むので経済的です。燃料の酸化防止剤も入っているようなので、冬場のバイク保管時に入れておくのもありだと思います。

特に変化は感じない
相性もあるかも。ワコーズF1のほうがいいと思う

Worked for a generator more in description
Cleared a blocked system in a generator for that 5 stars....for a car where most if it went into didn't get the result I wanted but I was thinking maybe one more bottle but I get rid of car in the end...so I still think its worth a try if you've the money to give it a go I know I will in the future with other cars to see how it goes...but it got a 6 kW generator going again.

A Must Cleaner For High Mileage Gasoline 4 Wheelers
A good amount of difference felt and smoothness ... A good cleaner to use often ... world wide recognition for this brand... will be buying it frequently.. First time users empty the whole bottle in fuel tank when nearing empty and fill full tank fuel and use the whole fuel up to almost empty before refilling.. and then for regular usage half bottle is enough for one full tank..IMPORTANT : THIS IS NOT A PERFORMANCE PRODUCT...

Efectividad y eficacia.
Este sí tiene los elementos para que realmente ayuden al motor y otros elementos como los inyectores, tiene los materiales que linouan y cuidado con otros que solamente dañan empaques.
