Q: What happens if I forget to add your fuel additives to the fuel, or only use it occasionally?
A: Of course you will get the most benefits if you remember to add our FTC catalytic decarbonizer and/or CRD Fuel ENHANCER at each refuel, but if you forget, you will simply dilute the benefits. If you keep forgetting, the short term benefits such as fuel savings and engine performance will be first to go. Longer term, engine deposits, oil usage and wear will return to pre-treatment levels. Beware of “rattle” in CRD/CD/CDI engines at any time, especially at start-up .. “rattle” is a sign that something is wrong with the injectors. You can of course re-start getting the benefits by again using the products.
