110 octane in a car

Would it be safe to put 1 gallon of 110 octane(leaded) or 101 octane(unleaded) with 16 gallons of 87octane(unleaded) into a 2003 Impala LS or any car. If it is, would there be any benifits.

Re: 110 octane in a car

leaded fuel will trash a catalyst, so no.
if the car is rated for 87 octane, then there will be absolutely no benefit to using higher octane fuel.

Re: 110 octane in a car

leaded fuel also clogs the o2 sensor so it will not work

Re: 110 octane in a car

Lead was used to raise octane in the past, and no longer necessary in current fuels. Listen to these guys; higher octane only benefits cars that require it.

Re: 110 octane in a car

Using higher octane can someitmes rob power too. Higher octane fuels burn slower, and your engine MIGHT not even be able to run on that gas.

ivymike, I thikn there IS a benefit to using higher octane...it keeps your fuel lines and injectors clean (I think)

This is a common misconception. By law, oil companies are required to add the same amount of detergents to all octanes.
