For a 2001 Ford E-250 : The gasoline engines use " regular " unleaded , 87 octane
It is used in lead-acid car batteries and used to be added to gasoline, to improve combustion (octane level).
No. Premium has a little less energy than regular. (Diesel has more) You use premium gasoline because it explodes a little faster, and will prevent the engine from knocking. Your owner's manual will explain what octane level of gas you should use.
What octane of gas should I run in my 1992 Toyota pick up 22re
To anyone who does not know what this means who is reading this, '93 gasoline' describes the level of octane (as measured by a special chemical equation) in a gallon of gas. 93 level octane (as it is called) will have no affect on the average engine, and it is only a myth that it will improve performance or mpg in a car. So the answer is no, it will only affect your wallet (cost of 93 versus a cheaper fuel) unless you happen to own a car with a high compression engine it is a waste of money to buy a higher octane than your car was designed to use. In fact newer vehicles with computer controlled fuel management systems requiring 87 octane will be harder to start with a high octane fuel.
91 octane
That all depends on where you live. If you at or near sea level, you will want to use gasoline with an octane rating of at least 92. That would be like mid grade or higher. If you live at higher altitudes, like 4500 feet or higher, you can use regular. The thinner the air, the lower octane rating needed. However, the octane rating that you use is what you should stick with. It's not good to be changing octanes all the time.
The owners manual says 93 octane.
The avgas sold at most airports is 100 octane.
These days, all gasoline sold is unleaded. The term "premium" refers to the mixture used, such as the octane level and any additives, like engine cleaning enzymes.
I have a 04 Lincoln LS V6 and it uses premium grade fuel (octane 91+). there should be a sticker in the inside of the fuel door that 'll tell you what octane level you should be using.
Gasoline does not have a measurable pH because pH does not apply to hydrocarbons.
