- Why is the sulfur content in gasoline limited?arrow_forwardPump gasoline may contain a small amount ofalcohol. Name three problems that can occur ifthere is an excessive amount of alcohol ingasoline. What percentage of ethanol does E85contain?arrow_forwardThe primary difference between these non-road (off road) types of diesel fuel is one contains a red dye and one does not. Otherwise the two diesel fuels are relatively identical. In some states there may be a higher level of sulfur in the off road diesel. From a regulatory perspective, the off road diesel tank is not regulated and is not required to have the leak detection, spill prevention or overfill prevention that a regulated tank is. Why is regular diesel fuel regulated (underground storage tanks) and off-road not regulated?arrow_forward
