Get a manual. Check the brake fluid and coolent. The coolent should not be green! It is also a good idea to change the brake fluid once in awhile. I don't know what kind of oil that is, try doing a search you will find more info then you want! I recomend Mobil 1 10W-40 or if you want Dino, Castrol High Mileage 10-40. (I have had good luck with Castrol)
