Can I use Diesel Injector & DPF Flush and Diesel Kleen at the same time?
We do not recommend using both products in the same tank at the same time.
- Use Diesel Kleen +Cetane Boost at every fill-up as your primary fuel additive for ongoing performance and protection.
- Use Diesel Injector & DPF Flush as a monthly deep-cleaning treatment. Simply use the Flush for that one tank instead of the Diesel Kleen.
