I had seen a post on it before but can't seem to find it again. Large forum here. What is the warm up period from a cold start again in the summer months? 2-5miles? 10-15min? A few short trips killed my mpg average by 2mpg, would like to preserve that. Lol. Thanks in advance.
You can use the trip meters to measure the effect: Power up but not to READY by not pressing brake. Reset A and B trip meters Press brake and Power to bring the car to READY Drive some test distance, I recommend 1 mile Reset one trip meter, rolling or stopped, and continue drive When you stop, take a photo of A and B trip meters Use them to calculate the difference, the initial warm-up drive My experience is once my car reaches 40 MPG, the warm-up phase is over. My typical mileage is 55-60 mph for a 10 mile commute. Bob Wilson
