I had a bad experience using a Valvoline Quick Lube shop. I had them use the conventional oil change back in November or so with them. My engine was immediately noisier, and made awkward clicking noises. It also seemed to have affected how it worked, it jerked once in a while. Pricing however was very fair. I think it was $30 including topping off fluids. Their full synthetic was about $50 for up to 5 QT it was on sale.
Went to Walmart the next OC they used Castrol GTX. Ran smoothly and was more quiet.
