Yes they do!!! It is called "blending". Not all midgrades are a blend though. Originally, each product had a dedicated storage tank and pumped a specific grade or octane. Currently, some of these systems still exist and are termed "straight" meters. A majority of the fuel dispensers now only have two octane storage tanks, typically 87 & 92/93. When you select 89 for example the pump electronically determines the proper mix or "blend", (if its working correctly). It may mix 70% 87 and 30 % 93 for example to arrive at 89. However, this is a progamable function and this ratio is adjustable. I generally only buy midgrade from a straight meter. On the blends I buy only low grade or high grade, which functions as straight meter delivery. On the subject of octane. "Most" , (47) , states have some form of a fuel quality program to monitor fuel octane etc. Currently (3) do not. Pennsylvania, Utah & Alaska. Why these (3) do not feel the need to monitor the quality of their fuel being sold to their taxpayers is a good question? I guess oil companies need somewhere to unload their questionable product? Pennsylvania lawmakers, for example, have been quoted as saying there is no evidence of a need to monitor fuel quality. Coincidentally, Pennsylvania pays the highest fuel taxes in the nation and is the 7th largest user of gasoline in the nation. Certainly for the consumers of Pennsylvania in particular this should be raising a few eyebrows. Apparently gasoline producers and sellers in Pennsylvania have earned the trust of the legislature in order for them to feel comfortable enough to look the other way when it comes to performing this function. Or, it could be that all the taxpayers in the (47) other states with a program are just wasting your money.
Pump gas can, but most race fuels do not.
3.487*1013
65% of 87 and 35% 93 to make 89 octane gas
83 octane pump gas.
I'm asking the same question, just spent $500 (reasonable, too) replacing fuel pump, filter, sending unit due to ethanol deterioration. I know of a Shell station that has "Marine Gas" which is 89 octane non-ethanol, for the price of their 93 octane.
Unleaded pump gas. I run 91 octane in my 525 KTM.
Exxon and Mobil are two gasoline companies that merged in 1999. Since then, each one accepts the other's credit cards. But in addition to Exxon stations and Mobil stations, there are some independent gas stations that make arrangements with one company or the other to accept their credit card. There is no rule about this-- the gas stations that make this arrangement will post it near the pump, usually with a sign that says "we accept the Exxon Mobil card here."
Many gas stations in Michigan have a kerosene pump.
The manual calls for 87 octane. I use 91 octane in mine and it helps with the pinging sound. Try it.
There is no octane in gasoline... it is the equivalent of octane.
Full service gas stations require companies to hire more employees to pump gas, check oil, etc. Companies make more profits when they hire less employees, and customers have accepted pumping their own gas. Also, it helps keep the price of gas from being even more high than it is when customers pump their own gas, and employees do not have to be paid to do it.
As of today, Aug. 6th, 2007, a gallon of 95 octane gas costs $5.28 at a self-service pump.
