I work in the oil business, with the price per barrel going up they are trying to add more and more ethanol to the mix and the majority of the fuel suppliers have at least some ethanol content. Ethanol gets worse mileage in any gasoline engine.
here's some info for thought:
70% of a barrel of oil is used for fuels.
Less than 1% of a barrel is used for finished oils like motor oils, grease, and gear oil. Thats why the market for fuel oils reacts alot quicker than that of lubricating oils. Either way its all going up! And the guys at the top of the pyramid are getting rich while us at the distributor level are seeing shrinking margins and increased competition! BTW- Most oil companies are going to see an increase in the price of base oils in May, so if you have a favorite brand, like an outboard oil, now is a good time to stock up and it has a long shelf life! And NO, I dont sell outboard oil-LOL!
