Does weather/temperature affect pinging/knocking?

Question

All factors such as octane ratings aside and being equal, is a car less likely to ping or knock when the weather is cold.

Answer 1

The car will be somewhat less likely to ping in cool temperartures.

Answer 2

No it doesn't. If theres a pinging noise the its most likely the octane of fuel your using. Read you owners manual and see what octane of fuel it recommends. If it recommends the octane your using then up the octane and use chevron gas they have the best. And if your engine has a lot of miles on it the engine might just be worn out and getting ready to throw a rod.

Answer 3

I think it does, I had an isuzu Rodeo that pinged and knocked til the cows came home, but one year we had this tropical depression come over us dumping a bunch of rain for 20 hours straight, I never heard it knocked during that storm

Answer 4

Yeb. Just yesterday I was listening to a jeep engine "singing". Everything was doing just fine. It was cold and when that car is hot knock, ping knock ping.

Answer 5

Not relating to gasoline, but your engine oil. Cold tempature will cause your engine to knock or ping more when you first start it, untill the oil gets warmed up. Think of it like syrup. When it is cold it is more think, and as it warms up if flows more easily. As your oil warms up it will coat everything then the knocking or pinging will stop. I don't know if it relates to your question but I figured I would throw it out there.

Answer 6

Depends, whether your car is rated a 93 octane only, it will do that, but if regular nah its something else. Like it needs a good tune up.

Answer 7

yes,high temp and low humidity will contribute to the engine running hotter and make it more prone to ping
