Is super/ultimate unleaded petrol really worth it?
Answers:
If you car does not require super unleaded, then there is no advantage in using it. Super unleaded actually retards combustion that may occur in a region simply due to high temperature. In order to get the most out of the gasoline, you want the flame front to travel in one distinct direction, away from where you've ignited the spark (at the spark plug).
In most engines, this is not an issue. However in racing engines where you get high compression. Gasoline can begin to ignite simply due to the heat and high compression. This may cause other flame fronts (spontaneous combustion) to develop that may even hinder the flame front leaving the spark plug. This usually results in a reduction of power, and is associated with knocking of the engine as the flame fronts collide.
If you do not hear knocking noises coming from your engine, your engine is not at a high enough compression to where it develops, then you will gain nothing by using super unleaded. However if you hear engine knock, literally a knocking noise coming from the engine compartment, then a higher octane gasoline should prevent the knock and give you more power.
Worth what? It gets slightly better mileage and slightly lower emissions, but it cost more.
It depends upon your "ride".
If your engine is a high compression, delicate, and particular one, yes, it is worth it.
If you are running many classic, vintage beauties, yes, it is worth it.
Etc.
Not really, the higher quality is a bit better on the environment, but most cars, even high performance cars run great on the cheap stuff. You can run the high end petrol in your car once a month or so, but it isn't needed every time, it doesn't make enough difference. Cars are made with such an amazing filtering system that it is not needed.
With vehicles built from 1996 to the present that Require it, Yes.With Older vehicles, no. I've come up with a way to turn Regular Pump Gasoline into a High Octane Propane Vapor Fuel.My System utilizes Air to accomplish this,100 Parts of Air to 1 Part of Fuel, with an Increase of Horsepower,and Fuel Economy of 50 to 75 MPG, with lowered Emissions.Engines run best on Vapor, not Liquid.But, by Law, all Engines from 1996 to the Present are Required to Run at 14.7 Parts of Air to 1 Part of Fuel.If I'm Wrong, then how is it that Engines DO run on Propane? Petroleum is all the same, it's only the Dispersal that's altered! So, to answer Your Question, for Your Nissan, Honda, Toyota,Mazda,Etc.,yes,Super is really worth it!
