Every time I go in for an oil change, they always pressure me into replacing something that I know it doesn't need replacing to make me fork out more money. I now know for sure that's their business tactics. I'll never go back to these guys again.
Luckily, I found an honest shop recently who carries my preferred and manufacture preferred 5W-30 synthetic oil. Even with the synthetic oil, it was cheaper than Royalty Auto Service's regular 10W-30 oil.
The car I took to Royalty was my beat up zombie commute car, which I really don't care for putting too much money and effort into. This time, I had to service my "day off" car, so, I took it to another place I found with a good reputation. I would never think of taking my good car to Royalty after what I went through with my zombie commuter. Moreover, Royalty Auto Service charges too much for parts, as well.
