Very cheap compared to buying it locally, here in my country. Used the Ceratec with the Leuchtlauf High Tech oil. 143K miles on my 2.5 mk6 Jetta. It started to make some tappet/lifters noise, very minimal but it was there. As soon as I started the engine, and about 30 minutes in , I could clearly hear the difference. How I heard the difference? With the hood closed now I can barely hear the engine, unless I put my ear close to the grille. Now I only hear the working injectors. Totally recommended. Can’t speak about gas consumption, I’ll have to drive 500-1000 miles to speak confidently. Recommended for giving older engines a longer lifespan. Update: After 15 days or so, and about 150-200miles later, I noticed my Jetta’s engine feels lighter and smoother. No placebo effect, it’s just there. Since I bought two Ceratec bottles, I used the second bottle on a Mitsubishi Outlander Sport with the Mivec 2.0 engine. These engines are quite noisy, specially the injection noises, and I had a very concerning lifters ticking. I did my oil change yesterday, and today the ticking is gone, all I did was use Liquimolys engine flush, Valvoline oil and the Ceratec. I’ll post an update if I get better fuel economy and smoothness on my Mitsu.

Durable and well fitting

Durable and well fitting. I drive a Honda Accord 2014 and when the under engine covers started falling off I used these to replace the ones that came off. They work well and the prying tool made replacing the retainers easier.
