Review on 🚗 Motorkote Catalytic and Exhaust Treatment MK-10351 - 16 fl. oz (1 Pack) | Emissions Control & Cleaner | Efficient Emissions Test Prep by Kendrick Dooley

The thing works. Also with these two others: DURA LUBE Severe Catalytic and Exhaust Treatment Emissions Test Catalytic Cleaner 16 fl. oz, 1 pack, HL-402409 B07HB7YVFG plus Red Line (60103) SI-1 Complete Fuel System Cleaner - Gas and Injector Additive - 15 oz Bottle B000CPI5Z0. Honda Accords 1990 Failed smog in California. More than twice the hydrocarbon limit. 1 bottle each of these 3 cleaners in a full tank. Drained a full tank. The number of HCs has been halved. Almost failed. Same again: 3 half tank bottles from these guys finished the tank this time. Far below the limit. Hooray! I don't know if or which of the 3 could have been more important, but I didn't risk it. This stuff WORKS.
