LM 5153 Pro-Line Fuel injection Cleaner 500 ml

So far so good. My car is kept well-maintained so I'm using this as a preventative measure for injector health rather than waiting until something's wrong. I'm planning on adding one can per year.

Best cleaner on the market

Decent quality item.

It seems this product works. Probably will buy again one.

Great choice. Can notice the difference

I used to use the non-proline injector additives, only realized that that have more of lubricants effect than hard cleaning. After using the proline: 1) full tank of fuel + proline 2) run to half tank fuel, then top to full tank normally 3) complete the full tank of fuel I felt the engine wasn’t running smooth comparing to the standard injector additive, and I do feel the engine runs very hard at phase 1) and 2). Fuel economy wise has little change. Making sure do 1) and 2) when you are travelling long distances on highway, I did at least 150miles at 60-70 motorway After the proline is completely clean up from my fuel tank, I still feel the car runs much smoother than before. Without technically inspecting, I think there are some improvements. With the standard injector cleaner (none-proline), I get the reverse effect: with the additive the car runs smooth, without it runs very rough…. This makes me think the proline product is mainly focusing on cleaning the engine and removing carbon, where standard injector additives is used for lubricanting after hard cleaning with this product. Very expensive, but it seems to be worth it - once every 5000 miles.

You only get better MPG while the product is in your tank, the next tank you fill you're back to normal. Basically this is just a fuel injector cleaner, and it does the job well. That is all.

Really not sure if it worked or not?

Un altro ottimo prodotto della Liqui Moly. Prima di sostituire la pompa della benzina ho voluto provare questo prodotto per sbloccare il galleggiante, perchè non veniva segnalato il livello di benzina nel serbatoio. Incredibile ma vero, ho aggiunto tutto l'additivo nella mia Panda benzina/metano con serbatoio pieno di benzina a tre quarti e poco tempo dopo, girando a benzina per una decina di minuti circa, ho risolto il problema: il livello della benzina è tornato ad essere segnalato normalmente, la pompa è stata sbloccata e ho risparmiato i soldi della sostituzione. Gli altri benefici di aver usato questo prodotto li sto constatando nel tempo.

good quality and value for money, satisfied with the product sure recommended

Producto original y efectivo. El motor va más suave tras usarlo. Recomendado

ممتاز جدا ، بعد استخدامه يجعل سحب السيارة خفيف وكأن السيارة جديدة

Very good, but he cleaned well and got the dirt all the way to the catalytic converter...but it's good.
