This valve cleaner helped my old subaru breathe a bit easier
This little bottle rode in my daypack next to my trail snacks 😂. Picked it up for my 2011 Subaru Outback because the idle was getting rough and I do long highway drives to mountain trailheads most weekends. I just poured the Liqui Moly Valve Clean into a half tank of gas at the station on my way to a hike, super simple. No funnels, no mess. After that tank, the engine felt smoother on the climb up the canyon road. Acceleration got a bit more responsive and the annoying slight hesitation pulling onto the highway pretty much faded. My mileage nudged up by about 1–2 mpg on my usual drive to the same trail, which was a nice bonus. The bottle size is small enough that i can stash a spare in the trunk organizer with my recovery straps and first aid kit. The measurements on the side are easy to read, so I just eyeball the dose for about 50 liters of fuel. One thing that really made me glad I grabbed it was how much quieter the engine sounded when I crawled through traffic after a long day on the trail. Less sputter, more smooth hum 🙂. I’ll keep using it every couple months before big mountain trips.

This keeps my staff cars running
This stuff lives in our break room cabinet. I run a gym and most of my trainers drive older beat-up cars. I grabbed this so they could treat a tank once in a while instead of ignoring the engine until something dies. First use was on my own 2010 hatchback that was idling rough. I dumped a can in, filled up, and by the next day the idle felt smoother and throttle response was better pulling out of the lot. Now I just toss a bottle to any coach who complains about hesitation or knocking. Small thing, but it keeps their cars reliable so they show up on time.

Good for older trail car engines
I grabbed this Liqui Moly Valve Clean for my 2011 Subaru that hauls me to trailheads every weekend. Poured a bottle in before a long climb up a dusty forest road and the idle felt smoother by the time I got home. I just wish the bottle had clearer markings for smaller fuel tanks.

A small bottle for routine maintenance
Since I rent a small apartment and don't have room for many car-care supplies, I picked up this 150 ml bottle to try on my older petrol hatchback. I added it to the tank before filling up after work, following the label directions. The bottle was easy enough to handle, and I like that I could use it without setting aside time for a separate cleaning appointment. The car ran normally on my commute the next morning. I can't honestly say I noticed a clear change in how it drives, though, so the effect is hard to judge from one use. For a basic bit of maintenance, it was straightforward, but I wish the result were easier to tell.

Daily driver runs smoother now
Driving a 14 year old Corolla, I got this Liqui Moly Valve Clean as a gift from my son who worries about my long freeway drives to visit the grandkids. I poured the whole bottle into a half-full tank, then took my usual 40 minute trip. The engine felt a bit smoother and the little vibration at stoplights calmed down, which made me glad he insisted on it 🙂. I like that I just empty it in before filling up. No fuss, no tools. The next morning it started quickly, even in our cool coastal air. For a small bottle, it fits easily in the trunk and I can keep one on hand for the next oil change or road trip 🚗.

I’ll probably grab another one next oil change �
About 20 minutes in, the throttle felt smoother and the engine didn’t shake as much at stoplights. Nothing dramatic, just less grumble and a bit more pep when I pulled out to pass someone. The kids even asked why the car sounded “less angry” 😂 which made me laugh.

Good for maintenance, but not magic
Given how much I drive for work, I grabbed this for my ten‑year‑old hatchback to keep the valves and injectors cleaner between services. I poured the whole bottle into a half‑full tank before a week of commuting and a Costco run. The engine does feel a bit smoother at idle and it seems to start quicker on cold mornings, which is nice when I am rushing to get my daughter to daycare before heading to the office. I did not see any big change in fuel economy though and the car does not suddenly feel stronger. I will keep using it every few oil changes, but I treat it as simple maintenance, not some big fix.

Aditivo de gran calidad
Esta marca Liqui Moly es de origen alemán por lo cual ya habla de calidad respecto a lo que se encuentra en el mercado Mexicano, de hecho es raro encontrar algún competidor de su tipo, pues los demás son limpiadores del sistema de inyección y este es un limpia válvulas para motores a gasolina. Su uso es bastante fácil, solamente cuando tengas que llenar tu tanque de gasolina agrégalo -trae ya su pequeño embudo- antes de cargar por completo dado que lo puedes usar en tanques que van desde los 40 a los 75 litros de gasolina, si tienes un vehiculo con un tanque de mayor capacidad considera adquirir un par de estos. El resultado es que resuelve problemas de ralentí inestable, el motor en baja se siente con menos vibraciones, auxilia a bajar los niveles de emisiones para la verificación -cabe aclarar que no verifico en CDMX- y la respuesta al acelerador mejora ligeramente. No esperes una mejora sustancial puesto que estos aditivos son para limpieza fina no obstante con nuestras gasolinas -siempre he usado magna- yo lo recomendaría usar cuando menos cada 5 mil km como mantenimiento. Lo usé en dos vehículos diferentes uno modelo 2006 y uno modelo 2013 sin problemas.
