Ouch! That price is way too high. You can do about as well using Exxon-Mobil's best oil, M1 AP, or even the old M1 EP has a good slug of PAO in there too.... I currently run Pennz Plat 0w20 because it was $13 for a 5-quart jug after rebate, so I cheaped out but got a very decent oil. Ravenol asks too much.
