Thanks guys. Sorry for the delay in reply. I have a picture using test 6 below.
Also, when I took my car to another mechanic to fix a squeaky rear suspension it konked out just as the guy was going to move it. Sure enough on the 1/4 fuel mark and low fuel light on. Put some fuel in and started again.
hopefully the above picture is posted, otherwise will post again.
I will monitor test 6 as I drive.
