Manuals determine the use of premium gasoline in imported models due to the higher octane rating of the fuel, but is it really necessary?
And then the owner of an imported car looks at the owner’s manual and discovers that there is an instruction to fill up exclusively with premium high-octane gasoline. And the question is: do you really need it?
SEE ALSO:
Not always, as the premium recommendation is made for its higher octane. It turns out that our gasoline, due to the added ethanol, already has a higher octane rating, even our common one.
In addition, even if the octane rating is a little lower than what is expected for the engine, it now adjusts electronically to this lower octane gasoline and, therefore, there is no problem for the engine.
