Diesel Oxidation Catalyst (DOC) Cleaning

Give your engine the care it deserves.

Bring your clogged and dirty Diesel Oxidation Catalyst (DOC) to DPF Guys for the best emissions systems cleaning services in the USA. We offer pick-up and delivery, 24-hour (or less) turnaround, and if we can’t clean it you don’t pay. Having your DOC serviced per the manufacturer’s recommendation by experienced DPF professionals still saves you hundreds of dollars over the cost of total replacement. You can trust your run-down or clogged-up diesel emissions system components in the knowledgeable and capable hands of our experienced technicians. We work hard to restore your DOC to like-new condition, and if we can’t, you don’t pay. 

How are we different?

Our commitment to treating others the way we like to be treated. Home to a team of highly skilled technicians, we work to ensure that your catalyst stays in optimal condition with expert DOC maintenance and cleaning. Regularly maintaining your DOC is vital for proper engine operation and exhaust flow, not to mention avoiding the need for total replacement and unexpected downtime down the road. A dirty DOC can lead to decreased engine performance, poor fuel efficiency, and create serious damage to your aftertreatment system or other portions of your diesel engine. Keeping your DOC in check can help reduce stress on your engine and prevent the cost of replacement by hundreds of dollars.

Schedule your DOC cleaning service and experience the difference yourself.
