It won't hurt the engine but it will hurt the catalytic converter.
No it does not affect
If there is a pinging sound in a 1995 Honda Civic engine, the engine could be out of oil. If the engine was operated with no oil for a period of time, the rings and pistons could have become damaged or broken.
Yes. It's a higher compression engine which requires a higher octane level to help prevent "pinging" in the engine. This engine does have the intelligence built-in that detects "pinging" and retards the engine timing to prevent to pinging from occuring. Pinging is when the gas explodes early while the piston is still going up. This can cause damage to the piston over time, something that's expensive to fix. If you put 87 octane in the tank the car will detect the pinging early, retard the timing to save the engine but the fuel economy and performance goes down. Generally speaking you'll pay more in gas by dumping 87 in the tank than filling it up with the good stuff since the performance is better.
Excessive spark knock (aka, pre-ignition, pinging) can cause serious damage to the engine if not corrected.
Bad performance ,pinging ,engine detonation,over heating, just too name a few.
The sensor senses when the engine is pinging or called spark knock. It then sends a signal to the engine control module. The engine control module then temporarily retards the timing until the pinging stops.
Check the engine timing first. Pinging or knocking,especially under acceleration could be early detenation caused by advanced timing.
depends on engine... compression ratio etc. i have a 94 lt1 with 10.5 compressin ratio most car engines are 8-9.5...:( 91 or better won't hurt if you don't need it. but if you do you will notice a knock or pinging sound under hard acceleration or going up hills.
You would probably hear a spark knock or pinging under acceleration or load. Check engine light may come on also.
Severe spark knock (pinging) can damage the engine. Knock sensors detect spark knock (pinging) in the engine. They send that info to the ECM (Engine Control Module). The ECM makes temporary adjustments in engine timing to eliminate the spark knock.
if you mix the ratio right with the gas it will boost power to engine as far as hurting engine i cant see why it would hurt it .
