2005 Volvo S40 T5 m66

Just used this the other day and so far the car seems more responsive. Time will tell if it really cleans out the system, but I trust Liqui Moly Products.

I use it once a year on my 2016 BMW 328i. Keeps injectors clean and carbon from accumulating where it shouldn't. So far, my car is still running like the day I bought it. This is one of those products you should never "notice" unless you are doing a bad job maintaining your car.

This product work great for my 2007 C350 and recommend this along with Liqui Moly injection cleaner. I used both cleaner once in my car before a California smog test since I have over 135,000 miles on it. My car past the test without any issues plus the engines sounds better.

Perfect to help remove any moisture in the fuel lines and liven-up your fuel injectors after a car has been sitting for (without starting) for past 6 months or longer.

I have been using this product on all my previous BMW and now on my 2010 BWM X3 3.0i. It surely keeps your fuel system clean. When used in tandem with top tier gasoline, it is highly effective in my opinion. Highly recommended. E. K. Akdogan

Have used this product four times with no noticeable change. Perhaps it works but no way to tell. Will stop using this once I finish the two remaining cans

Can’t see it working, but I’m sure it does. No science behind that statement. But it does make me feel good knowing I’m trying to keep it running smooth. Like taking your vitamins, it helps, even if you don’t see an immediate change.

I like this product more than the Chevron Techron. I notice a little more low-end torque and smoother revs. Makes my 20 year old M3 feel alive again.

Works like a charm
