If you put leaded gas in an engine that is designed to run on unleaded gas, while the engine will run, it will not run optimally and you will ruin the catalytic converter.
Yes you can use premium gasoline in unleaded because premium gasoline is also unleaded. The only reason it is called premium gasoline is because it has a higher octance then regular unleaded. Regular unleaded has an octane rating of 87 and premium has an octane rating of 92. Premium gasoline burns slower then regualr gas because it has a higher octane rating.
any 440 takes premium gas.
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.
No, premium is unleaded gas as well and the difference in octane ratings between regular (87) and premium (91) is is not going to cause an engine to seize. Running the gas/oil ratio to lean will though.
always premium gas
Most likely it is Regular Unleaded gasoline. I suggest you consult your owners manual it will tell you what to use in there.
Premium.
Yes. You can use unleaded, plus, or premium. Premium is 97 octane wich means it burns alot cleaner and richer. As there of unleaded is 87 octane. Premium will make your engine run better. And for eco friendly people...its "good" for the ozone.
You can use either regular unleaded or premium unleaded.
They're usually Regular Unleaded, Mid-Grade Unleaded and Premium Unleaded.
Of course you use unleaded gas. I don't know where you would find leaded gas these days. Are you referring to PREMIUM unleaded gas? Yes, the manufacturer suggests you use Premium octane gasoline in the Nissan Juke (91 or better).
