🔥 Revitalize Your Fuel System with Red Line's Complete SI-1 Fuel System Cleaner - Gas and Injector Additive Treatment (12 Pack Case) Review

I can't attest that this completely solved my problem but I think it helped. I have a 2004 Toyota Sienna with 188,000 miles on it. In the last 6 months it has started issuing code P0420. That's twice as much for each tank of fuel. I tested the O2 sensors with torque. They looked normal. My tank is almost empty. Clean air mass meter. (Use only MAF cleaner) Air filter replaced. Added and refilled Red Line to an empty fuel tank. I'm on my second tank of gas now and I'm not giving out any codes. I…

Redline SI 1 is the most efficient injector and cylinder head cleaner. Why? It has the highest concentration (30-50%) of PEA, a polyetheramine. PEA is considered the most effective chemical cleaner for injection systems, cylinder heads and valve heads/stems. Do your research on Redline and the web, Google. It also cleans the upper cylinder. The competition is closing in, but the Redline seems to be holding on to No. 1 status. One reviewer seemed very upset that its gas mileage didn't skyrocket.

If you buy gas from any gas station other than Chevron or Shell, this product is a must. Gasoline is exactly the same at all gas stations, but they have different levels of detergents, which keep the fuel system and engine clean. Use the bottle twice a year just before an oil change. This fuel additive has the highest percentage of polyester amine based detergent on the market. Do not try other products. I've heard that some people only use 1-2 oz (from a 15 oz bottle) on each tank of fuel and…

My car was starting to run sluggishly so I figured it needed a tune up or something. I took it to the dealer and they offered to flush the coolant and motor oil. $100 service. My car is only 4 years old and has 73,000 miles (approx). It didn't make sense to me, but I'm a woman, so I guess they thought I didn't know. I started googling possible problems and saw suggestions for a supplement. Then I came across this product at Revain with great views. Compared to the cost of purge systems, it was…

This is not snake oil for high mileage vehicles. Excellent stuff. If your car is running sluggish and/or pinging, this will correct the situation. I put Red Line Fuel System Cleaner in my 2011 160,000 mile Prius, which made a chirping noise when accelerating from a standstill while under heavy load from the engine and A/C compressor (hot California summer). no more noise He also fixed a sluggish 2008 Nissan Versa with 90,000 miles on it. I dumped it into a nearly empty fuel tank before…

The Nobel Prize in Science and Technology isn't going to be awarded to Redline this year, but that doesn't mean it's a bad product. I have been using Redline products in our vehicles and with customers for over a decade and this company has found nothing but excellence. Their oil and additive formulas have shown significant improvements over the cars I've installed them in and Si1 is no different. Now, using this in hopes of making your factory engine brand new will likely lead to frustration…
