Pep Boys OEM Brand Concentrate, unlike Toyota Red LL, is a long service interval PHOAT AF. It has the longer service interval of the current PHOATS like Toyota SLL pink that only come as a premix, but comes as full strength. It's the only concentrated PHOAT I'm aware of that actually states the longer service interval on the jug and pds/sds. The 150k miles seems optimist, imo. More like ~5 years, 50-60k miles, which is about what the vehicles manufacturers recommend on subsequent to FF interval.
So if you can find it, use it. Seems to be getting more difficult to find at PBs.
