Went in for an oil change and fuel filter on my duramax. Was told by the service guy it was $255 which I figured sounded right. Truck got done and they told me it was over $400!!! Didn’t mention the $175 labor charge and environmental fee on top of that. Pretty disappointing to say the least considering I bought all the OEM parts from Oreilly’s for $117. 10/10 do not recommend.
