What maintenance should I do on my SUV on a regular basis?

I bought a truck last summer, a 2003 Chevy Blazer. It's running very well, has 180k on it. I'm only 19 and I'm not quite sure what I should be doing to keep it in good shape. I do oil changes every three months, check tire pressure and fluids regularly. Is there anything I should also be doing on a regular basis like tune ups? Air filter changes? And if so, how often?What maintenance should I do on my SUV on a regular basis?you don,t have to change the oil that often unless you put a lot of miles on it. stuff like gas and air filter, check the pcv valve, check the transmission fluid and if it looks dark change it and the filter. spark plugs and wires, keep the suspension greased like ball joints and tie rods, grease is cheaper then parts ! there,s a few things you can do to keep it running good.What maintenance should I do on my SUV on a regular basis?The owners manual usually has recommended service. Air filter after 10,000 miles, spark plugs every 50,000, etcWhat maintenance should I do on my SUV on a regular basis?thats pretty much all the maintenance you should do but also have them check the rubber gaskets on the car occasionally because if that breaks it could be a 1400 dollar repair. Not from the gaskets but fluids leaking. This shouldnt be a problem until the car is ten years old or if you drive fast or accelerate full throttle often. In conclusion, just take care of your car and never ignore lights on your dash. Hope i could help.What maintenance should I do on my SUV on a regular basis?You would be very smart if you have the engine de-sludged. You can do it yourself with Seafoam or Amzoil crankcase cleaner. Swear off regular engine oil FOREVER, and switch to the Mobil One product that states, %26quot;designed to meet or exceed GM specifications.%26quot; ALWAYS read the label on oil you use, forget advertising and word of mouth stuff. This oil will continually clean your engine as you drive, and PREVENT power robbing sludge formation. Use the %26quot;0W%26quot; weight meeting GM spec's. You will save money, since the oil only needs changing once yearly. CLean your throttle body, plate, and IDLE AIR CONTROL VALVE often. These little items affect power and MPG's. Use Amzoil Foaming Cleaner, if you can find it. Use it to clean your PCV valve and hose. Run it through your throttle body to clean piston tops, rings, and valve stems. When you are sure your engine is showroom, install a set of Nippondenso Iridium plugs. Watch your power boost by 20% and your MPG's rise about the same. THese plugs react with the fuel and improved response results. If you can't find the Nippondenso's, then use Bosch FUsion or Platinum single points. Even GM doesn't use AC/Delco plugs anymore in their top of the line units. They simply are too inefficient. Good luck!!
