My sweetie has a 2007 Prius with about 93K on the clock. She bought the car new, and it's been very well maintained. She puts less than 5K per year on the car now ... this year (2020) will be less than 3K, 98% in town. I'd like a decent quality oil that can handle a once-per-year OCI. For convenience and cost, I'd like to stick with Walmart as the source. Was thinking SuperTech and QSUD. Prices on those a quite good now. What else is worth considering? Would like to keep the cost down as I'm spending someone else's $$$. Will probably go with a Fram Ultra filter.
