1978 Mercedes 450 SL 112,000 Miles, what shoul I use in this car for motor oil ?
1978 Mercedes Benz 450 SL needs to have a oil change. I have been using Quaker State Blend 10W40 here in southern Atizona. Is this a good oil to use in this car ?
10W-40 should be good.
I've been using Quaker State oil in my vehicles for over 30 years and never had a problem. HTH. -Jim
