That's exactly what happens. Its the ECU protecting the engine. I imagine that applies to most modern cars, especially turbo's. Its a long time since I last heard and engine pinking. (Pre-ignition). Back in the day that was fairly common. BTW I can remember from the 1970's whenever we went to...
If you want max performance from your Subaru Impreza they you either have to run it on avgas or put additives into the 95 octane fuel. (I imagine this applies to a number of other hi performance turbo's). If you don't then the ECU will throttle back the power quite significantly.
A high octane is not always required at the altitude of Johannesburg (5,500 feet), which is why 98 octane is not available on the reef. It simply isn't necessary.
One important consideration is that if far too much oil is put into the engine a situation can develop where the crankshaft throws go through the oil as the crankshaft turns. This can lead to frothing of the oil where there are more bubbles than oil. Eventually the oil pump will have only air to...
For the past 55 years I've always checked oil levels when cold. But the year 2000 Ford Fiesta Mk4 that I use for local trips specifically says to check the oil level when the engine is hot.
I recently set up an "el cheapo server" using a R490 MXQ Pro 4K TV box from Takelot and a USB 500Gb Hdd that I already owned. The TV Box has phono outputs which I have plugged into my amp and hdmi connections for the TV. It talks to my router should I wish to use the internet. To get around any...
I took this photo of the moon using a Nikon D5600 with a 70-300mm zoom lense on a tripod. Exposure was a 250th at F6.3 on ISO 100. Since you're photographing the reflection of the sun a long exposure is not required.
Worth noting that if you are old, you can jump the queue at both the licensing department and Home Affairs.
Also useful to go to an optician to do the eye test. Removes uncertainty and speeds things up a bit.
Interesting description of what happens to a full size submarine that implodes.
From Twitter.
A submarines crush depth is a fraction of Titans.
And Titan has no hydrocarbons on board so different type of explosion.
