if you just got the car I would do maintence first get the oil changed and then drvie it for a week or so and sea foam it and change everything including the oil again but with a high quality and a good filter, then do your fuel filter, and plugs. Then when you get some more money do a pan drop. After that flush your cooling system throw in a 180* T-stat and your good to go maintence wise for a good month or 2 untill you change the oil again. From here I would go read the safetly modding your car thread
