Before anything is added, the technician confirms the engine and the product, and DEF, the diesel exhaust fluid in its own tank with a blue cap, is a separate system that this service does not touch. ★★★★★ 4.7 stars from 952 Google reviews Modern diesels from Ford, Ram and GM run injection pressures many times higher than a gas engine and use injectors with extremely fine tolerances. That precision is why they are so efficient, and it is why fuel quality and the right additives matter. A diesel that has sat for a while, run a lot of short trips or burned questionable fuel can build deposits at the injector tips that change the spray pattern. ## Diesel symptoms we hear about Owners describe a rougher idle, a little more smoke on a cold start, a slight loss of power pulling a trailer, or fuel economy that has slipped. Some of those can come from deposits; others come from a fuel filter, an air filter, a sensor or the emissions system. We tell you what the pattern looks like and whether a cleaning is a reasonable step. - Rough idle after warm-up - More smoke than usual on cold starts - Less pull on the grade with a load - Mileage down without a change in use ## DEF and the fuel tank Diesel exhaust fluid goes in its own tank, usually behind a blue cap, and never in the fuel tank. Fuel system cleaning works on the fuel side only. If your DEF level is low or the truck shows a DEF warning, that is separate from this service and the owner's manual says how to handle it. ## The visit Pull the truck into the bay and stay with it. The technician confirms the engine and fuel system type, uses a cleaner made for diesel fuel systems, and follows the product's steps. Many diesel owners pair it with a [diesel oil change](https://xpressoilandlube.com/services/oil-change/diesel-pickups/), which takes larger oil volumes than a gas truck. ## Timing and the cold Diesel makers do not generally list a cleaning interval; it is condition-based. Fuel filters, on the other hand, do have intervals in the manual, and a clogged one causes many of the same symptoms. Cold is the other local factor: Minden averages about 75 nights a year at 20 F or colder (NOAA 1991-2020 normals), and diesel fuel can gel at low temperatures if it is not winter-blended. That is a fuel issue, not a deposit issue, and we would say which one it looks like. ### Sources - [carcare.org/car-care-guide/](https://www.carcare.org/car-care-guide/) (Car Care Council car care guide, inspection and replacement guidance for filters, wipers, batteries and fluids, read 10/15/26) - [ncei.noaa.gov/products/land-based-station/us-climate-normals](https://www.ncei.noaa.gov/products/land-based-station/us-climate-normals) (NOAA 1991-2020 normals, Reno-Tahoe airport, Carson City and Minden stations: hot days, freezing nights, precipitation, snowfall, read 10/15/26) - [leg.state.nv.us/nrs/nrs-487.html](https://www.leg.state.nv.us/nrs/nrs-487.html) (NRS 487.6875, written estimate and authorization before additional work, read 10/15/26) ### Your service center: Reno Northwest - Call [(775) 787-1000](tel:+17757871000) Mon-Fri 8 am-5 pm, Sat 8 am-4 pm, Sun closed - Address 6100 Mae Anne Ave, Reno, NV 89523 [Directions](https://www.google.com/maps/dir/?api=1&destination=6100+Mae+Anne+Ave%2C+Reno%2C+NV+89523&destination_place_id=ChIJ3dFA7yBEmYARYg1CtQTi_Bk) ### What a customer said Carson City I am glad I chose to take my care here. The mechanic changed my oil, transmission fluid, and air filter for me in no time at all. And I was very thankful that he stayed later than they are open just to service my car.

Call your service center or drive in; there is no appointment to make. ### Can you use a regular fuel injector cleaner in my diesel? No. Only products made for diesel fuel systems are used on a diesel. ### Does this service include DEF? No. DEF is a separate fluid and system; fuel system cleaning works on the fuel side. ### Will it help with cold-start smoke? If deposits are part of the cause, it can. Glow plugs, fuel filters and gelled fuel cause similar symptoms, and we say which way it points. ### How often should a diesel get it? Most makers publish no interval. We recommend it when symptoms and history point to deposits.
