Fuel Nozzle Color Codes

Which hose is for your engine?

Beware gas pump nozzle color mix-ups There are no legal requirements for fuel nozzle colors.

Gas pump nozzle color mix-ups can hit your wallet. Gasoline is routinely dispensed through nozzles that may be red, white, blue, black, green or almost any color of the rainbow. Sometimes the colors vary with the grade of fuel (regular, mid-grade, premium), but at other stations they are all the same.

Good info. If I recall correctly the nozzle on the diesel pump is much larger than the gas. Maybe not in all cases. Occasionally I pump diesel in a can for the tractor.

Occasionally I’ve run into a pump where they reverse the order of the grade and in my haste I select premium when I think it’s regular. Around here it’s regular, mid, premium from left to right. I always wondered if it’s a little trick to get you to buy premium. Probably not.

One of my guys put 75 gallons of gasoline in my diesel international. Cost me $1200 to have it drained on the highway. He used a green nozzle.

Green was always diesel when we had our diesel Touareg a few years back. I thought that was universal, but apparently not. As Greg pointed out, the dispensing nozzle for the diesel was always much larger and wouldn't fit into a gas powered car.

I just grab the nozzle that has the lowest price above it.

Most of our pumps have two nozzles at most. A green one for diesel with a larger tube diameter so you can't accidentally put it in a gas tank and a black one that pumps everything else dependent on the grade of fuel you select on the pump. I will have to check to see if real E-85 stations have a separate line. We sell a lot of "standard" 85 with the reverse 15% ethanol but the 85% ethanol you have to look for.

My car's engine is flex fuel compliant. On the drive to California about 18 months ago I did try some E-85 in Nebraska or possibly southern Utah. The price difference with mid grade gasoline was impressive (they only offered E-85 ethanol for basic no-lead). The reduction in fuel range on a full tank was also impressive. Car ran fine, just not as far :lol:

I went back to where my guy got diesel. They had yellow for diesel and green for gas. I was told by the station manager “ pay attention to what you’re doing “ . He is 100 percent right. The guy who screwed up is always on his phone with ear buds in his ear. Pay attention and trust nothing. Check twice

I'm still working on the color coding issue - apparently reading the label is too hard to do?

A lot of performance cars require 91 or above octane. E85 is a good substitute. 91 and above can cost 50 cents to a dollar more than regular 87 octane or E85. If the car require the higher octane. The reduced mileage is made up for in the reduced price.

to run on E85 the computer needs to be reprogrammed for it. E85 is also used in drag racing. They don't worry about the mileage.

A good friend of mine in Kansas runs 3 circle race cars. They use straight alcohol.

I think here in PA the diesel is designated by green and is usually on the left (local Sheetz). The gasoline pump nozzles have the octane numbers on them. I just got 5 gallons of diesel (should be put in a yellow container, red for gasoline, and blue for kerosene). Used to be some diesel was dyed (for purpose of taxation).

Your fuel oil is dyed for tax reasons and tracking.

He has access to a dynamometer?

Also, you have to tune the engine to run on E-85. It doesn't necessarily get the HP boost automatically. What you gain in HP you loose in mpg.

It was done by a performance shop with a dyno. His cellphone is used to change timing and fuel pressure.
