You have to find a brake specific fuel consumption chart for your engine. That’s the only way to know for sure.

I agree with the advice to let the car run for a minute or two until the idle settles down a bit. But I also agree that it’s ok to let it run for 10 minutes if you want the cabin to warm up.

Needing the car to warm up for 10 minutes is a holdover from carburetors I think. They just weren’t as good at metering fuel in extreme conditions, and the cars simply wouldn’t drive until the coolant got a little heat into it to warm up the carb.

All an air fryer is is a toaster over with a fan. You just can’t see the heating element. So not much safer.

But yes, a much more versatile choice. Just get one that fits a full size frozen pizza.

If you have a good enough meter, you can test the resistance of the coil and e see if it is in spec.

Why would they print it if it wasn’t accurate?
