My 01 civic has 170,000 miles and a small oil leak developed. Car has used dino 5w20 (Quaker State) most its life. I switched to valvoline maxlife 5w30 and am never looking back! Motor is much quieter and leak has completely stoped over the last 1,000 miles using the Maxlife oil. Very impressed with this oil,my new choice for this car from now on. Thanks for the recommendations guys,I really appreciate you all.
