Thx tex, does it require premium gas as recommandation or it can take regular gas as well?

Question

Does it affect warranty claim if I gas it with regular...

Answer 1

If a manufacture says the car requires premium gasoline, you must put premium gasoline in the vehicle.

Let me explain...

The reason for requiring premium is because the engine is designed to be a performance engine. This usually means that the engine has a high compression to give your better performance and power.

However the higher compression also requires you get gasoline that does not pre-ignite, or believe it or not more resistant to spontaneous ignition. This means you'll need a higher octane (more resistant to ignition).

The lower the octane number, the easier the gasoline will ignite. Which means if you put lower octane in a high compression engine, you'll get something called pre-ignition or spontaneous ignition. This basically will generate a flame front that is at various points in the cylinder that is not at the location of the spark plug, where the desired igntion point is.

Usually pre-ignition occurs where the piston and cylinders meet. This means it will generate a flame front that is opposing the flame front from the spark plug when it ignites. (This will also cause loss of power)

When this occurs as the flame fronts meet (the ones from the cylinder walls due to pre-ignition, and the ones from the spark plug), you'll get a shock wave generated. The shock waves over time will cause piston and cylinder/head damage, typically seen as pitting.

What is normally heard from drivers is commonly described as pinging, and the damage that can occur will void a warranty.

You can always try a lower grade of gasoline, but if you hear noise coming from the engine, you'll understand why. If you don't hear noise from the engine, you might be safe. Some vehicle manufacturers understand that people want to save a few bucks and so they add a knock sensor that retard's spark. This lowers engine compression simply by retarding spark to a less than optimal point. Honestly to me it seems like a waste to do this. If you're buying a high performance vehicle. typically premium is only $0.10 more per gallon than regular, which means on a 15 gallon tank, you're paying only $1.50 more. The savings in engine wear and tear is well worth the extra $1.50 a tank.

in case you stress LIKE a woman. In intense potential with lots of precise foot that ought to no longer be sensible pinging is detonation interior the motor, no longer tender burning of gasoline. automobiles designed to run top type may even get a pair extra miles a gallon on the coolest stuff. So broken valves decrease overall performance OR run the appropriate grade. automobile would not ping run time-honored
