Is it really better to use high mileage oil and oil filters on older cars?

I have a beretta that has 208,000 miles and just started using fram high mileage oil filters and GTX high mileage oil. Does the high mileage really make a difference or am I just wasting money? Thanks. Oh yeah and if I am just wasting money what kind of oil and filter should i be buying?Is it really better to use high mileage oil and oil filters on older cars?
The high mileage oils contain aditives that help keep your seals pliable and do a better job of removing sludge.





The filters often have a PTFE additive that helps combat friction as well as denser media to help trap more of the particles high mileage engines produce.





I have a 91 car with 255K miles on it. I started using the high mileage stuff when it had 75K on it and it still runs great, no leaks and doesn't use oil between changes.Is it really better to use high mileage oil and oil filters on older cars?
i have found that it is bad to change the oil brand that has been use for long periods.its better to keep useing the same oil that got you those 208,000 miles......if i eat beans for 90yrs and doctor try to change my diet.....no way
The high-mileage oil does work. I know this from experience and research. They add a lot more additives in the oil which help the engine run better despite wear.
