Formula Shell 10W-30 GF5 Conventional Motor Oil ,1 Quart

from Olds1957

This oil has been used in my 1984 Cadillac Eldorado since it was brand new, 33 years and 89,000 miles later I had to replace valve cover gaskets, and was astounded by how clean the engine was. I change the oil every 3,000 miles or once a year. I maybe put 500 miles a year on the car now, so it do...

VERY GOOD OIL - NEEDS A $2.50 PRICE POINT
