I agree with this. As soon as a service person tries to sell me a power steering flush I typically will never go back to them. I always thought that was BS. Apparently, my suspicians were correct.
Question. My girl has a 97 corolla with 90K, which should get in the 30's in terms of mpg. I bet it gets in the low 20's at the moment, horrible. I changed the plugs and wires, no effect. What should I do next? Fuel system cleaning?
