Check engine light (CEL) on your diesel? Before you book the shop, know this: a lot of DEF-system trouble is just white crystal buildup choking the SCR — tank, lines, injector, all of it. That buildup steals power, spikes fuel use, and can drop you into limp mode.

Clogged SCR = expensive repair.

Rislone DEF Crystal Clean (p/n 4784) dissolves those deposits and restores SCR function from one bottle, poured straight into the DEF tank. Safe on your emissions system, won't void your warranty. Cleans the crystal buildup – guaranteed, or your money back.

Skip the dealer repair bill. → https://bit.ly/4bdswGp

Gas is up. Repair bills are up. Everything's up. Here's where you claw a little back: a clean emissions system burns less fuel – and clearing a problem now beats a far bigger repair bill later.

Three Rislone formulas do exactly that. They scrub your fuel, exhaust, and emissions system, restore lost power and mileage, and turn off the check-engine light. All guaranteed.

CAT Complete (p/n 4720) – gas engines. Cleans your catalytic converter and fuel system, clears P0420 and other codes, passes emissions.

DPF Clean (p/n 4744) – diesel. Unclogs a blocked DPF, restores lost power, clears P242F and related codes.

DEF Crystal Clean (p/n 4784) – diesel. Dissolves the crystal buildup choking your DEF/SCR system and brings power back.
