Although there are some low cost treatments which are not bad, you should always try to make sure you buy a well known one or one which has been recommended to you by your mechanic or someone who knows what he is talking about. Another great way to buy your treatments is when they are on sale which happens very often in many stores.

After you have bought right treatment, you should wait to add it until next time you will add gas to tank. This way, you should add treatment, with a maximum of one bottle, and then add gas you wish. If you have any doubts regarding fuel treatments you should ask your mechanic, or, in case you have doubts on how to use it you should ask treatment manufacturer for further advice. You shouldn’t add any treatment to your car if you are not sure about it and what it could do to car.

Once you know which proper pressure for your tires is, you are ready to check them. In order to do this, you must unscrew caps on tire air valve and press tire pressure gauge against it. You should make sure you keep tire pressure gauge as firmly against tire valve as not to let air come out from it.

Once you have tire pressure gauge connected with tire valve, gauge will immediately tell you what tire pressure is. This will allow you to learn weather tire needs more air or its air pressure is correct. If it needs more air, you should do it carefully in order not to pass its air limit. And, in case its air pressure is correct, you simply need to disconnect air pressure gauge from it and screw valve cap back in its place.
