My car is older so I'm not sure if the "synth will cause leaks" applies to this car or not...?
I'm kinda going with Castrol either part synth or full. Not sure if full is worth it. Will the car run smoother, cooler, more power etc?
Also not sure if High mileage oil is a gimmick or should it be considered? My car has 100k miles now.
Thanks for your help.
