After all the M1 flap, I have decided to switch to Red Line for my wife's Subaru. My intention is to use an OCI of 7500 miles.
I would appreciate thoughts on this move and also, what oil filter is up to 7500 miles.
I had been using M1 every 5K miles and a OEM oil filter from Subaru.
Thanks guys.
What Subaru vehicle are we talking about here? Is it normally-aspirated or turbo-charged? If it isn't turbo-charged, I'd say you really don't need to use Redline oil. M1 or GC should be able to go 7,500 miles without issue in a N/A Subaru engine. Heck, my last OCI with GC in my turbo-charged Subaru WRX STi (325 HP) was 6,883 miles...and the results were excellent (minus what appears to be a minor coolant leak). Here's the UOA:
