I first of All received the product much ahead of time. So the Delivery was very instant. Very well packed. Thanks to the seller. I used this to my Mercedes c350 and Porsche 991.1. You can feel instant difference. If you buy it, you will not regret it!

Not Good Quality

I observed the significant improvements from stop and go to acceleration.👍

I did a little ‘research ’ on fuel additives and which was were best and as advertised. Red Line always came out on top. The chemicals used to clean the fuel system and top end of the engine are very effective. There are some others that are very effective but this led the group. I haven’t had the chance to compare fuel consumption yet but the pickup and idle seems to have improved.

Had some misfiring issues due to dirty fuel injection. This product help clear that up. No issues since.

This fuel system cleaner pours easily and seems to help smooth out performance. It didn’t make a dramatic overnight change, but over a couple of tanks it felt like the engine was breathing cleaner and running more consistently. Value for money: Worth it for regular maintenance at this price. Ease of cleaning: Simple pour-in no mess or hassle. Works well: Helps improve throttle response and smooth idling. Leakage: No leaks or spills during use. Paint quality: N/A (no effect on paint). Protection: Feels like it supports overall fuel system health.

Works great, and Amazon comes through again. Thanks
