If you're nervous about going 10,000 miles or more between oil changes, then do it every six months, when you probably should also have your tires rotated (also explained in your owner's manual). GM says to change your oil at least once a year even if the service indicator warning light doesn't come on.
Click on âFileâ and select âSave Asâ after youâve entered all data into the spreadsheet. Select âCSVâ under the âSave as typeâ dropdown menu. Type a name for your CSV file, then select âSave.â You have now created a CSV file, and commas will automatically be added to the file to separate each field.
You can also use a text editor like Notepad++ or GenScriber to open CSV files but large ones will be very difficult to work with in these types of programs. Open Freely is another alternative but with the same problem with larger CSVs. Microsoft Excel supports CSV files too, but the program isn't free to use.
