Thank you for Review: 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。 Review: 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. ## Features - Cleans to nearly 100 percent efficiency in one treatment - Reduces need for octane by up to two points - Contains synthetic upper cylinder lubricant - Safe for continual use - Use one bottle per tank for most effective treatment of neglected vehicle ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000CPI5Z0 | | Amazon Bestseller | #180,688 in Automotive ( See Top 100 in Automotive ) #1,123 in Oil System Tools | | Brand Name | Red Line | | Contains Liquid Contents? | Yes | | Customer Reviews | 4.6 4.6 out of 5 stars (5,053) | | Global Trade Identification Number | 00083522601030, 07262318274969 | | Item Form | 液体 | | Item Volume | 443 Milliliters | | Item Weight | 454 g | | Manufacturer | レッドライン | | Model Number | (60103) | | Part Number | 60103 | | UPC | 083522601030 | | Unit Count | 443 Milliliters | ## Product Details - **Brand:** Red Line - **Contains Liquid Contents:** Yes - **Global Trade Identification Number:** 00083522601030, 07262318274969 - **Item Form:** 液体 - **Item Volume:** 443 Milliliters - **Item Weight:** 454 g - **Manufacturer:** レッドライン - **UPC:** 083522601030 - **Unit Count:** 443 Milliliters ## Images ![Red Line (60103) Complete SI-1 Fuel System Cleaner - 15 Ounce - Image 1](https://m.media-amazon.com/images/I/71y6nZvissL.jpg) ![Red Line (60103) Complete SI-1 Fuel System Cleaner - 15 Ounce - Image 2](https://m.media-amazon.com/images/I/81lgAaNzDnL.jpg) ![Red Line (60103) Complete SI-1 Fuel System Cleaner - 15 Ounce - Image 3](https://m.media-amazon.com/images/I/81BIvx5SC7L.jpg) ![Red Line (60103) Complete SI-1 Fuel System Cleaner - 15 Ounce - Image 4](https://m.media-amazon.com/images/I/81WuROLrdvL.jpg) ![Red Line (60103) Complete SI-1 Fuel System Cleaner - 15 Ounce - Image 5](https://m.media-amazon.com/images/I/81zs+0d5hnL.jpg) ## Questions & Answers **Q: Can u detail the procedure how to use this product?** A: Hold bottle in left hand. with right hand, twist cap counter clockwise. Break foil seal on bottle. (if you smoke, put the cigarette out before proceeding further)open gas tank door. remove gas cap (place in a location you remember to reinstall later.)Pour contents into gas tank. Replace gas cap. Drive as normal and it will clean injectors up as you drive. Enjoy a beer (AFTER you drive with enough time in between to sober up.)Call the fellas up and stand around drinking beer while admiring a fine product from Redline. (PEA is the main thing you want to clean things up, which Redline and Techron have the most)//I hope that is detailed enough\\ **Q: Is this product better than the much cheaper STP fuel cleaner** A: if you buy cheap gas, you might need it. i get top tier fuel and never had the need for this. i tried it on a twice for a 17 y/o honda odyssey. did nothing. i always use top tier fuel. also honda V6 is a great motor, as is there 4 cyl so maybe no need for this unless you use cheap gas or have a man engine prone to injector issues **Q: Will this Redline product damage my 02 sensors with LONG TERM use? No one seems to address this issue.** A: Actually, notably, I put this product in a 1997 Toyota Camry a few years ago. The car was over 20 years old and had only had basic crap gasoline (not Top Tier and no fuel system cleaners) in it for its entire life. A few days after I added it, the check engine light DID come on and it WAS a broken O2 sensor. However, I'll do it again in a heartbeat, because a new O2 sensor was $13 and took 10 minutes to replace. So it seems it is possible that using this with an extremely crusty vehicle will cause an O2 sensor error/failure. But with long term use, certainly not. I have been using this in my 2016 Mazda 3 several times a year for 5+ years and it is running like the day I got it. **Q: diesel engine, LPG engine all use??** A: Definitely do NOT add this to a diesel or LPG fuel tank or anything else that isn't normal gasoline. However, as someone else said, they do make one for diesel engines. It is Red Line 60302. ## Customer Reviews ### ⭐⭐⭐⭐⭐ 私の中ではヒット商品です *by 移***ん on September 5, 2023* 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 *by M***W on December 17, 2019* 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.
