Oil Gauge Spiking
Starting yesterday, my 2005 GMC Envoy warning light to check the oil gauge
started to come on. When I am driving, everything is fine, but when I stop, the
oil gauge starts to vary from the midway point to almost zero. This only
happens sometimes and that is when the warning light comes on. I have
moved from Texas to Colorado a few months ago but this is the first time this
has happened. Also did the same thing when parked for more than a minute. I
know that it is not time to change the oil as I have done it fairly recently. Is this
likely an issue with the gauge?
