2002 Subaru 2.5 w/ 52,000k: use ARX?

[poison]

I've maintained my car well from 11000-52000 miles, using a number of good oils in that time, with the last 15,000 being on GC at 5-6000 mile OCI's. I use OEM or K&N filters.

I drive fairly hard. OK, very hard!

I have a bottle of ARX, and was wondering if I should use it, or if there is no need at this point.

If there is no need, I will be running Redline 5-10/30 or 10/40.

Any opinions on this?

Thanks!

Well, even if you don't notice huge results from it at least it will "reset" the cleanliness clock on your engine.

Preventive maintenance is better than waiting for it to get dirty.

Can't hurt, but don't expect the "OMG, I get 3 mpg more now!" like the high mileage guys.
