Diesel Only Decal Pair Matte and Gloss Fuel Tank Sticker

Description

A two-piece diesel only fuel tank sticker decal set offered in a matte and gloss finish pairing, made for truck owners who want a clear, weather-resistant label at the filler. Available in 4, 8, 12 or 18 inch sizes.

Why a Diesel Only Fuel Gas Tank Sticker Decal Set Matters

Misfueling a diesel tank with gasoline is an expensive mistake, and a clear label at the filler is the simplest way to prevent it. This diesel only fuel gas tank sticker decal pair gives you two matching decals so you can mark both sides of a truck, a transfer tank, or a bed-mounted fuel container. One decal is printed in a matte finish that reads cleanly under bright sun without glare, while the second is printed in gloss for high visibility under lights or low-light conditions. Each decal is cut from durable vinyl and laminated to resist fuel splashes, road grime, and pressure washing when applied to a clean, dry surface. Choose the size that fits your tank, apply, and let the label do the talking.

Matte and Gloss: Two Finishes, One Clear Message

Every set includes one matte decal and one gloss decal, both printed with the same bold DIESEL ONLY lettering and pump-style iconography. The matte option sits flat against textured tank surfaces and painted bedsides, cutting glare so the text stays readable from a distance. The gloss option adds a smooth, easy-wipe surface that sheds dust and wipes clean with a damp cloth, which is handy around fuel pumps and greasy hands. Because both decals carry identical wording and layout, your labeling stays consistent whether you place them on opposite sides of the truck or split them between the main tank and an auxiliary container. Both finishes are printed with printed inks to help the lettering hold its contrast through sun exposure.

Sizing Guide: 4, 8, 12 and 18 Inch Decals

This set is sold in four decal sizes so you can match the decal to the space you have. The 4 inch pair works well for filler doors, small transfer tanks, and toolboxes where space is tight. The 8 inch size is a popular middle ground for standard pickup bedsides and most auxiliary tanks. The 12 inch decals suit larger saddle tanks, semi-tractor fairings, and flatbed frames where you want the message readable from a distance. The 18 inch pair is built for big rigs, bulk fuel containers, and heavy equipment where a small label would get lost. Measure the flat area where you plan to apply the decal before ordering, and allow a little margin around the edges for a clean install.

Application and Care for Long-Lasting Results

Installing each diesel decal takes only a few minutes. Clean the surface with isopropyl alcohol to remove wax, diesel film, and dust, then let it dry completely. Peel the backing, position the decal, and press from the center outward to push out air, working on a mild day if applying outdoors. The vinyl conforms to gentle curves on tank bodies and bedsides, and the adhesive bonds fully within a day or two. For everyday care, wash with mild soap and water or wipe with a soft cloth; avoid abrasive pads and high-pressure nozzles pointed directly at the edge of the decal. If you ever need to remove it, warm the decal gently with a hair dryer and peel it away slowly.

Frequently asked questions

Do both decals in the set say the same thing?

Yes. Each set includes one matte and one gloss decal with the same DIESEL ONLY design, so you can place them on opposite sides of a tank or split them between a main tank and an auxiliary container while keeping your labeling consistent.

Will these decals hold up to fuel spills at the pump?

The decals are laminated to resist fuel splashes and routine washing. Wipe spills with a soft cloth rather than letting fuel pool on the surface, and avoid abrasive pads or direct high-pressure spray on the decal edges.

What size should I order for my pickup's fuel door or bedside?

The 4 inch size fits filler doors and small tanks, 8 inch works well for most pickup bedsides, 12 inch suits larger tanks and flatbed frames, and 18 inch is intended for big rigs and bulk containers. Measure your flat application area first and allow a small margin around the edges.
