How long, depends on what oil. I would do my initial check at 5k, another at 7.5k, & one more at 10k. If all looks well, OA's every 5k. I'd change the factory filter every 7.5k & the by-pass every 15k, with make up oil as required. To my knowledge, the two best long-range oils (the most shear stable) are Schaeffer's 9000 & a Redline product. Most others (including AMSoil & other syns) shear in the first 3k, and then stabalize at a low 30wt.
I have no problems running DELO 400 to 7.5k, but I would go beyond that even with bypass due to the shearing.
