Regular 87 octane.
87 octane unleaded
87 octane is fine, but it will not hurt if you want to use a different octane...
The engine will not run.
Adding octane booster, or using higher octane fuel, will not hurt your car. Octane is actually a combustion inhibitor, not an accelerant. If your engine is truly knocking, it's because the fuel/air mixture, during the compression stroke, is igniting before the spark plug is expected to fire. (The fuel/air mixture, under compression, should not "explode" before your distributor sends the "Voltage" needed to make the spark plug fire. This should only happen at the very end of the compression stroke.) Adding higher octane fuel will prevent the fuel from igniting under compression, allowing the compression cycle to complete its phase to completion. Higher octane fuel also burns slower, so it may even smooth-out your idle. Either way, your car should be fine - Just make sure your plugs are gapped properly, and knocking is really the problem - The best bet is to just go up one octane level at the pump. If the problem goes away, stay with that grade fuel. If not, go up to premium - And check again. (If your vehicle is designed for 87 octane fuel and you need to burn 91 octane fuel to stop knocking, I'd seriously consider having a mechanic diagnoe the problem.)
a dingo is faster it goes 59 mph a jaguar only goes 44 mph
Zona Jaguar goes by Z.
87 octane
Josh Moltane goes by Octane.
Preferably, as the 4th (and 5th generation for that matter) Honda Preludes are fuel-injected, it's suggested that they take in 91 octane or higher.
Owners manual states that it holds 16gals of fuel. It also states that when the fuel light goes on , you have burned 14gals of fuel and have two gallons remaining. When the needle reaches the empty line you have burned 15gals of fuel but you really have one gallon of fuel left in the tank.
Pull the gas tank down and you will see where the pump goes into the tank.
