Keeping your vehicles running good is not that hard to do. There are a couple things you need to keep up with that is Oil, Tires and your breaks. Now you can change your oil on your own but for just around $25.00 you can have the professional do the work for you and you know that it is done well. They will also check your tires for you but you need to tell them that you want it a little low for winter driving and they will know where to set the pressure. They might suggest to rotate them as well which this will prolong your ware of your tires which I recommend. If you decide to change your oil on your own then you will need an oil-filter and the right amount of oil with the right weight like 10w-30 for winter and heavy oil in the summer. Block your vehicle with wood or a rock for safety. Jack it up and place a jack stand under the wheel location blocks. There should be one for each side. Then slide under your vehicle with your oil pan and loosen your oil-filter with the oil wrench. Then remove the oil plug nut and clean it and place where you can find it. Let it drain for 10 to 20 minutes. Take the oil cap off and pull the oil dipstick out. Then after the time has gone then Put the new oil-filter in and put your oil plug nut back in. Now you need to know how much oil your vehicle takes. If you do not know it will be ok. Just put 3 1/2 quarts in and wait for 5 minutes and put your oil dipstick back in and then pull it out. Then pull it out and look to see where the oil is on your dipstick. There is a mark on the bottom of your dipstick to tell you how much to put in. Just keep adding the oil till you see it in the range of the mark. Most of the time it is about 1/2 inch long. Add the wait 5 minutes, then check and so on.
