Is ethanol bad for old cars?

Older vehicles generally aren’t driven much, increasing the possibility that the fuel can draw moisture as it sits in the tank and lines, which in turn can lead to rust. They may also have cork gaskets or fuel floats, which Fawcett says can be damaged by ethanol, or rubber seals that aren’t compatible.

What happens if you put 93 octane in a 87 octane car?

Can higher octane hurt your engine?

The higher the octane, the greater its ability to prevent the unruly type of combustion engineers call detonation. The goal is to ignite the fuel mixture solely with the spark plug, rather than from the heat in the cylinder, to prevent detonation, which can seriously damage high-performance engines.

Can you still buy leaded gasoline?

Can you still buy leaded petrol in Australia? Leaded petrol was completely phased out of Australia after 1 January 2002 due to the harmful nature of its main ingredient, lead.

Can I use 100 octane in my car?

So, the moral of the story is; unless you have at least 12:1 compression (of more), do not run any 110 octane or higher race gas in it or you’ll go slower. If you have 10:1 – 11:1, you can run up to about 100 octane and be fine, but if you have in the 9:1 area, don’t even bother.
