The topic title about sums up my frustration. I am a 20-something female living in Orlando, trying to learn how to properly maintenance my 2005 RX330 with 50,000+ miles. I am so tired of taking my car in for routine maintenance (i.e. oil change, tire rotation) only to have a "mechanic" trying to charge me hundreds for flushes and filters, and all sorts of other things I know I don't need. I can't afford to take my car to the dealership for maintenance. I started changing my oil on my own. I take it to Tire Kingdom for other maintenance. Yesterday they told me I needed a $130 pwr steering fluid flush. The fluid is dark and low, but I don't want to pay them $130 to do it. They also say I need my transmission fluid cap changed every 30,000 miles. Any advice?
