What weight oil should be used in a 1998 Chevy venture with close to 84000 miles on it?

Answer 1

98 Venture engine oil specificationhave tne same year venture, owner's manual says:SAE 5W-30 is best for your vehicle, However you can use 10W-30 if it is going to be 0 degrees F. or above. also use only oil with the starburst symbol which means it has been certified by the American Petroleum Institute

i have a 2000 venture warner bros package and i use only mobil 1 filter and i have 102000 miles and then i use fully senthetic mobil one oil 10w40 with a quart of lucas fully senthetic oil stabilizer. it has never run better as far as no dry starts, it never clicks or taps..now it does cost a little bit more but you don't have to change your oil as offten.the extended proformance oil is recommended to change only every 15,000 miles as aposed to every 3 or 4 thousand miles. so you do the homework and decide how you want to treat your engine.
