it could, read the owners manual that came with your car. it will say what kind is recommended, the octane levels in gas vary and if you go to low you could cause your engine to knock and soon after blow.
Yes In a modern car changing from regular to premium is no problem It may have been costing you power and fuel mileage to run regular, but if your car does not need premium it is a waste of money. On older cars running regular may damage the engine, but we are talking cars built in the 1980s or older.
The Pontiac Vibe GT with the (1.8L 4cyl ) requires Premium Unleaded. The use of Regular Unleadedmay lead to predetonation or what is commonly called pinging. Although you may not be able to hear it, itmay be there. The Vibe's fuel/air managment system may be able to adjust for the regular fuel somewhat but at a cost of mileage and power. The engine requires Premium fuel, so burn Premium fuel. Burn Regular Unleaded and you risk engine damage.
you will run the risk of pre-detonation, which can potentially damage the engine, most have knock sensors which will pull back the timing to compensate reducing power and efficiency of the engine.
Yes, as long as it is not equipped with the optional supercharged 3.8 liter V6. That engine requires premium unleaded fuel.
This is a flexible fuel vehicle so you can theoretically use E85 or Regular Unleaded Fuel. For the very best performance use exactly what is recommended in your owner's manual. If it says use Regular, then use regular. The use of a higher octane than recommended is a waste of money and will provide no benefit whatsoever. If however it lists Premium fuel then use premium. The use of a lower than required octane may cause engine damage due to pre-detonation.This is a flexible fuel vehicle so you can theoretically use E85 or Regular Unleaded Fuel.

The engine fuel management system will adjust for the lower octane fuel. This will cause you to have less power and your fuel mileage may suffer. If you hear any pinging whatsoever from the engine switch back to the premium fuel immediately or you will have engine damage. If no pinging occurs you can use regular.
You will risk doing damage to the catalytic converter(s).
Empty your tank out, drain the fuel lines, as the gasoline will damage your diesel engine.
Yes, this engine requires Premium fuel. Using Regular fuel will cause pinging and engine damage.
It's not a problem in the slightest. Just drive it. Inside the combustion chamber, regular and premium are effectively indistinguishable since both explode, forcing the pistons down the cylinder. The REAL advantage to "super/premium" is the higher octane rating. A higher octane fuel explodes more slowly or evenly. High compression engines need premium, since the higher compression causes fuel to explode more rapidly. If the fuel explodes too rapidly, the engine "pings", not just making the characteristic sound, but it can also cause damage. Premium fuel eliminates pinging in high compression engines, and delivers the power of those explosions more evenly. High compression engines are not as popular today, since engineers have been able to deliver more power and efficiency with a lower compression engine. Using premium fuel in a modern, low compression engine will only burn a little slower and not damage the engine at all. It's just a waste of money to use premium in a low compression engine.
Bad idea. Most cars that are Premium Only are designed to take about 92 octane fuel at the lowest. The car will, in fact, run with super unleaded gas but it will create damage to your engine in the long-run. And if low octane gas is used frequently, it can greatly reduce the life of your car.
It is not just the 07 Civic SI, but the Honda Civic SI made after 06 requires premium fuel because it has a strong engine. It runs more smooth on premium fuel than regular fuel. Regular fuel will eventually damage the engine.
