I have an '06 Pathfinder that's starting to seep a little oil, and instead of running a high-mileage oil I thought I'd run some LM oil-saver as an alternative plus 0w-20 (since the LM would act as a thickener?) so that viscosity comes down to being a comparable 0/5w30 but a bit more frictionless.
Stupid idea?
