I have a 2007 GMC Yukon XL Denali w/6.2 liter Vortec.It has
I have a 2007 GMC Yukon XL Denali w/6.2 liter Vortec.It has 125K Mi. At idle, the oil pressure gauge goes down to the red zone when the oil is at operating temp. We use Valvoline Max Life semi synthetic 5-30. Recently while towing our camper trailer up a pass, we were running at around 5500 RMPs and the low pressure warning came on just as we hit the top of the pass. It then stopped sounding and was not heard again on the trip of over 200 miles. I did not hear any valves clattering. My GMC dealer took it in and says it needs a new oil pump as their external pressure gauge reads that it is around 8 PSI at idle with warmed up oil, and it should be closer to 20 PSI. This same dealer installed an oil pump about 18 months ago for the same reasons. They do not have an explanation as to why the oil pump has failed after 25K miles. Any ideas? … read more
