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.

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。

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.

An absolute bliss of product. Engine smoothens out completely and can be felt definitive. Used this vehicle for my 15 year old car (Swift), 24 year old bike (Kawasaki 125 cc, two stroke), Jawa 42 and Harley Street 750. Effect was pronounced in all vehicles and is a great product to use. Shall use this product all the time, so shall request the sellers to make available always.Every vehicle can use.....

This stuff is phenomenal! Used it in my 2014 Honda CRV with 155k miles.. brought mpg up and car is much more responsive and peppy. Will be using this and only this for my injector cleaner/carbon remover in any of my engines.
