What type of oil?
Engine oil works really good in engines. Try 5w-30. It usually tells you on the dipstick what it wants but not always.
It's in the manual. If you don't have one you can get one at www.helminc.com Always use what the owner's manual recommends. Sometimes the weight of the required oil is on the oil filler cap located on the cam cover. I would run synthetic Mobil1 oil with the manufacturer's suggested weight for 7,500 miles or 1 year which ever comes first. If you do lots of city driving chang it at 5,000 miles.
