Power Service Diesel 911 winter emergency diesel treatment 64 oz — relieves gelled fuel & de-ices filters

Power Service Diesel 911 (64 oz) is a winter emergency diesel treatment that reliquefies gelled fuel and de-ices frozen fuel filters to restore fuel flow and get engines running again.

When cold weather causes diesel to gel or fuel filters to ice over, vehicles can stall or refuse to start. Diesel 911 is formulated for emergency winter use: it breaks up gelled diesel, clears ice from fuel filters, removes water that promotes filter icing, and includes a lubricator to protect fuel system components during recovery. It’s not a seasonal preventive product—use it when fuel has already been affected or keep it on hand as a winter emergency solution.

How quickly does Diesel 911 restore flow in gelled diesel?

Diesel 911 acts rapidly to dissolve wax crystals and liquefy gelled fuel so the engine can draw fuel again. Time to recovery varies with temperature, the extent of gelling, and fuel system design, but the formula is designed for fast results in emergency situations.

• Designed for immediate, on-demand use in winter breakdowns
• Helps liquefy waxy, gelled diesel to re-establish fuel flow
• Effective on fuel in tanks, lines, and filters when used as directed

Can Diesel 911 clear frozen fuel filters and water in the system?

Yes — the product contains de-icing components that break up ice in fuel filters and help disperse free water that causes icing. By addressing both ice and water-related blockages, it helps reduce the common winter causes of fuel starvation.

• De-ices frozen fuel filters to restore filter function
• Removes or disperses free water to reduce refreezing risks
• Works in conjunction with fuel flow restoration to minimize downtime

Will Diesel 911 protect fuel system parts when clearing gelling problems?

The formula includes Slickdiesel Lubricator to help protect pumps and injectors from wear that can occur when fuel flow is interrupted or when additives aggressively treat gelling. This lubricity boost helps reduce the risk of damage during recovery operations.

• Contains Slickdiesel Lubricator to improve pump and injector lubrication
• Helps prevent increased wear during restart and recovery
• Compatible with common diesel fuels and other Power Service additives

Should I use Diesel 911 as a regular cold-weather additive?

Diesel 911 is formulated for emergency winter rescue rather than ongoing prevention. For seasonal protection against gelling, use Power Service Diesel Fuel Supplement +Cetane Boost (white bottle). Both products are compatible and can be used together when needed.

• Designed for emergency treatment, not continuous cold-weather protection
• Use Diesel Fuel Supplement +Cetane Boost to prevent gelling proactively
• Compatible with the preventive formula if simultaneous use is required

Who this is for: Power Service Diesel 911 (64 oz) is aimed at diesel vehicle owners, fleet managers, operators of heavy equipment, and anyone who needs a reliable emergency solution for gelled fuel and frozen filters. Keep a bottle in winter service vehicles, tractors, generators, or on job sites where low temperatures can disrupt diesel operation. Use it when fuel has already gelled or when immediate de-icing and water removal are required to restore engine operation.
