I was looking up warranty coverage for Mazda Colombia because of Pitter's post about issues she was having. I found the warranty booklet for Mazda Colombia and saw it has a section on engine additives. This a Google Translate copy/paste (pg 66)
Has anyone ever seen something like this before? That not using an engine additive will void part of the warranty?10. Fuel system cleaner
Fuel System Cleaner is an additive for use in Mazda vehicles with a
gasoline [engine], especially recommended for those with Skyactiv technology.
The additive specified by the brand guarantees the perfect functioning of the engine and maintains
deposits in injectors, valves and the combustion chamber. Non-use leads to loss of
warranty on all fuel system components.
Use fuel system cleaner at scheduled maintenance every 10,000
kilometres. However, if the vehicle is exposed to the following conditions, it is advisable
use the product every 5,000 kilometers.
• Short trips that do not allow the engine to reach normal operating temperature.
• Frequent starting and stopping conditions, such as those encountered in very busy urban traffic.
• Long periods of idling engine operation.
