What fuel does Ford recommend?

Ford generally recommends unleaded gasoline with an octane rating of 87 (AKI) or higher for most vehicles. Some engines, especially high-performance or turbocharged variants, may require premium gasoline (91–93 AKI). Flexible-fuel models can use E85 (up to 85% ethanol) when available, while non-flex-fuel models are typically designed for gasoline containing up to 10% ethanol (E10).

Fuel guidelines vary by region and model; always consult your owner's manual or the fuel-filler label on your vehicle for the exact specification. Ford also notes the potential benefits of Top Tier gasoline where available and cautions against using fuels not approved for your vehicle. The sections below outline octane recommendations, ethanol content, and region-specific considerations.

Understanding octane recommendations

The octane requirement depends on the engine and market. The following outlines common guidance drivers should consider when refueling.

• Most Ford engines accept a minimum of 87 AKI; higher-octane fuels can improve performance or prevent knocking in some conditions, such as heavy towing or hot climates.


• High-performance or turbocharged engines may require premium gasoline (91–93 AKI) to maintain peak power and efficiency; check the door jamb label or owner's manual for your model.


• In Europe and other regions, octane is measured as RON and guidance commonly falls around 95–98 RON; always follow local labeling and your vehicle’s manual.

Always verify the exact octane specification for your vehicle on the fuel-filler label or in the owner's manual to avoid incorrect fueling.

Ethanol content and Flex Fuel

Fuel ethanol content can affect performance and compatibility. Here’s how Ford advises handling ethanol blends.

• Flex-Fuel Vehicles (FFV) can run on gasoline or E85 (up to 85% ethanol) when the vehicle is labeled as FFV; follow the manual for grade handling, cold-weather considerations, and maintenance implications.


• Non-Flex-Fuel vehicles are typically designed for gasoline containing up to 10% ethanol (E10) where permitted by law; using higher-ethanol blends than approved can cause issues and may void warranties—check the owner's manual.


• Some regions have approved higher ethanol blends (such as E15) for certain Ford models; only use such blends if your specific vehicle is listed as approved in the manual or by Ford support.

When refueling with ethanol blends, use fuels approved by Ford for your model and region to protect performance and fuel-system integrity.

Regional notes and tips

Ford’s guidance adapts to market differences. Here are general region-specific considerations drivers should know.

• United States: Most models accept 87 AKI minimum; some engines or driving conditions may benefit from or require higher-octane fuel. Follow the label on the fuel-door or the owner's manual for your exact spec.


• Europe and other regions: Octane is commonly listed in RON terms (e.g., 95–98 RON); regional manuals provide the exact requirement for each vehicle.


• Top Tier gasoline: Ford encourages using Top Tier gasoline brands where available, as these fuels meet higher cleanliness standards that can help maintain fuel-system performance over time.

Regional guidance is crucial because fueling recommendations can differ by market and model; always verify with your local Ford materials or dealer for your specific vehicle.

How to verify fuel requirements for your Ford

Taking a few quick steps can ensure you’re fueling correctly and avoiding potential issues.

Check the fuel filler label

The label near the gas cap usually lists the minimum octane and any ethanol-content restrictions specific to your vehicle today, making it a quick reference at the pump.

Consult the owner's manual or Ford's official support

For model-specific guidance, refer to the official owner’s manual or Ford’s support site and talk to a dealer if you’re unsure about your vehicle’s requirements.

Summary

Ford’s fuel recommendations center on octane requirements, ethanol content, and model-specific approvals. In general, use unleaded gasoline with 87 AKI or higher for most models, with premium recommended for certain engines. Flex-Fuel models can use E85, while non-flex models typically use gasoline containing up to E10. Always confirm requirements on the fuel-filler label and in the owner’s manual, and consider Top Tier gasoline where available. Regional variations apply, so check local Ford materials for your exact market and model.

Does Ford recommend fuel additives?

Ford does not recommend the routine use of aftermarket fuel additives, stating that modern fuels already contain sufficient detergents. However, some Ford-branded additives, like the Motorcraft 44K fuel system cleaner, are recommended for use at specific intervals, according to some sources. The use of unapproved additives can be harmful and may void your warranty, so it is best to follow the manufacturer's guidelines. 
Ford's general stance

• Ford generally advises against the regular use of aftermarket fuel additives because modern gasoline already contains detergents to keep the engine clean. 
• Using unapproved additives can potentially cause damage to your fuel system and may not be covered by your warranty. 

Specific recommendations (as reported by some sources)

• Motorcraft 44K Fuel System Cleaner: Some sources suggest this product is recommended by Ford for use at every oil change (approximately every 7,500-10,000 miles). 
• Motorcraft Air Intake & Valve Cleaner: This cleaner is reportedly recommended by Ford for use every other oil change (approximately every 15,000-20,000 miles). 
• Motorcraft Anti-Gel Diesel treatment: This is a specific product recommended for diesel engines to help with cold-weather performance and fuel line protection. 

Key considerations

• Always check your vehicle's owner's manual for official recommendations on fuel and additives. 
• If you have concerns or your engine has a specific issue, consult a qualified Ford technician for guidance. 
• Using additives as directed and using only those that are explicitly approved by Ford can help prevent damage and maintain your warranty. 

What happens if I put 91 instead of 95?

But if your car is designed to take premium petrol, and it is fed a lower grade petrol than recommended, that's when issues can arise. For example, putting regular unleaded 91 RON in a car designed for the higher-octane 95 RON or 98 RON could result in knocking in the engine.

Why does Ford recommend BP fuel?

Ford recommends BP Ultimate fuel because it is designed to work with their engines to keep vital components clean and protected, which helps maintain optimal performance, economy, and emissions. This recommendation is part of a partnership between the two companies, and it is supported by BP's assertion that its fuel contains detergents that help prevent engine deposits. 

• Engine performance: Ford states that BP Ultimate works in harmony with its engines to keep critical parts clean and protected. 
• Engine cleanliness: The fuel's detergents are designed to prevent carbon deposits and keep the engine clean, which is particularly beneficial for modern, sophisticated engines like Ford's Ecoboost engines. 
• Partnership and promotion: Ford and BP have a history of joint promotional efforts, including branding gas caps with "Ford recommends BP" logos on new vehicles sold in the U.S. 
• Top-tier fuel: By recommending a specific brand, Ford is encouraging the use of a top-tier fuel that contains extra detergents compared to minimum-standard fuels, as a Reddit user notes. 

What gasoline does Ford recommend?

regular unleaded gasoline
If you drive a new Ford truck, car or SUV, regular unleaded gasoline should work fine for your vehicle. However, it's always important to read your Ford owner's manual for recommended fuel information.
