So I have a question in regards to my mothers car. She bought it new in 2002, has the 3.5 Ho magnum v6 in it. The kicker is this car has less then 80,000km, kilometers, not miles. It's only seen short trips most of its life. Like less then 10km a few times a week.
Now I haven't looked at the owners manual for it in a long time but I poked at her many years ago to run synthetic in her car and surprisingly she's listened, was just over there the other day and seen a jug of Mobil 1 5w30 in the garage.
My only concern is this engine recommends 10w30, 5w30 in some cases for colder temperatures but we don't live in an area that gets that cold and it's always parked in the garage. She's been running Mobil 1 5w30 for the past 5-6 years no issues.
I'm just wondering because of the type of driving conditions this car is subject to, would the 10w30 synthetic be a better option for protecting this motor during these short trips or is 5w30 going to be just fine? Don't wanna freak her out and tell her she's been using the wrong oil this whole time lol.
