I want to add an injector cleaner to a Nissan Tiida 2012. It has around 15000 miles and I never add any fuel additive. Sonax injector cleaner costs 20 dollars and 3M costs 10 dollars. Which one do you recommend me? Can you recommend other brands?

Why do you think you need to add either? Do you have a problem with the injectors? – Bob Cross Apr 3 '14 at 18:38
At low RPM the engine sometimes is lugging. I think the word in english is lugging. Also I will do it for general maintance. Also I will check battery fluid, I clean throtle, etc. – Roby Sottini Apr 4 '14 at 1:02

3M has always made quality products. I don't know the Sonax brand, so in the interest of fairness I'm going to assume it's very good. But if the 3M product is cheaper, I would gladly spend my own money on it.
