Hey guys the wife has been putting some long distance trips on our 02 Dodge Durango 4.7 which has left the engine down about a quarter quart low on oil. I'm still in the safe zone on the dipstick but I need to top it off. I was thinking about topping off with MMO since I have seen a lot of positive info here on it. Engine has 148,000 on it and I use Mobil 1 High Mileage 10w30 per research on this forum. My question is do you think topping off with mmo is a good move or worthless move? Thanks for any info.
