5 Tips to Avoid Fuel Trouble

View of fuel filter

Diesel-fuel quality can vary dramatically from source to source and even day to day. Fuel conditioners can bring most any diesel fuel up to acceptable standards. Available in summer and winter formulas, you can use John Deere Fuel-Protect Diesel Fuel Conditioner year-round to improve fuel quality and maximize engine performance.


Tip 1: Choose Wisely

John Deere Fuel-Protect Diesel Fuel Conditioner is a proprietary blend of additives capable of improving most any diesel fuel, providing comparable or higher performance than other fuel additives available over the counter. It is recommended for use with a variety of fuels, including low-sulfur diesel (LSD), ultra-low-sulfur diesel (ULSD) and up to 20 percent blend (B20) biodiesel. Both old and new diesel engines can benefit from using improved-quality fuel.


Tip 2: Use Before Adding Fuel

Add the conditioner before fueling to help the conditioner completely disperse and mix.


Tip 3: Don't Cloud the Issue

For the winter formula to work properly, it must be added to the fuel before ice crystals begin to form. Make sure you add it when outside temperatures are at least -9 degrees C (15 deg. F) above the diesel fuel's cloud point, which depends on the fuel type and blend. Your local fuel provider can tell you what blend you are receiving based on seasonal temperatures. Once added, the winter formula will typically protect down to about -7 deg. C (20 deg. F) below the cloud point.


Tip 4: Keep Winter Formula Warm

Store the winter formula at or above 10 deg. C (50 deg. F) because it contains a large amount of anti-gel that will freeze in its undiluted form before it is added to the diesel fuel.


Tip 5: Use Cost-Effective Summer Formula

During the summer or in warmer climates, use the summer formula, which offers the same important protective qualities of the winter formula without some of the more costly winterization components that prevent gelling and icing. Using a summer formula when appropriate will result in a more cost-effective solution for you.


Tip 6: Use in Your Bulk-Fuel Storage Tank

Add Fuel-Protect Fuel Conditioner to your bulk-fuel storage tank. The conditioner contains a stabilizer that should be added to any newly delivered fuel to maximize fuel storage and filter life while protecting your bulk-fuel storage tank from corrosion.
