BMW explains using lower Octane gasoline. "Thomas Plucinsky, BMW Product and Technology Communications Manager told us all BMW engines are designed to run on 91 octane. All performance testing, including EPA emissions and fuel mileage, is done with 91 octane. However, though BMW is all about performance, their motors will run on 89 or 87 octane
Certain BMWs do need premium fuel. These are the most typical causes for a BMW to need premium, but this is by no means a complete list. In the event that your BMW fits one of the following descriptions, avoid using normal gasoline in it:
E-85 ethanol is used in engines modified to accept higher concentrations of ethanol. Such flexible-fuel vehicles (FFV) are designed to run on any mixture of gasoline or ethanol with up to 85% ethanol by volume. E85 has an octane rating higher than that of regular gasoline’s typical rating of 87, or premium gasoline’s 91-93.
High-performance BMW can only perform well with premium fuel while some older models can do with regular fuel. Modern BMWs come with engine knock sensors that are able to detect the kind of fuel in the engine and adjust the starter ignition accordingly. This may lead to some slight change in performance.
Does a 2004 bmw 325i require premium gas? If not what is the lowest grade recommended? lion9car September 22, 2009, 12:21pm 2. Doesn’t your owner’s manual cover
While premium gasoline may be more expensive than regular gas, it is worth the extra cost for BMW X3 owners who want to get optimal performance from their engine. The higher octane rating reduces the likelihood of knocking, helps increase fuel efficiency, provides improved acceleration, and leads to better overall engine operation.
