If you were located in a really cold climate, either QSUD or M1 AFE would be the obvious choice. Both have standout cold specs.
Either would be a good choice anywhere.
I'd select between the two.
Having written the above, any 0W-20 would work well on drain intervals well beyond the 5K you anticipate for this thrifty little beast. With but 75 bhp out of 1.2 liters moving just 2100 lbs, this engine will not be hard pressed and longer drains would be okay unless the car is always short tripped. Yeah, sump capacity is limited, but our 2.4 liter Accord weighs another half ton plus, makes more than twice the power out of twice the displacement and has a sump holding only 1.2 quarts more.
The M1 currently has a $12.00/jug MIR while the QSUD features an $8.00 MIR, so either would be pretty cheap after MIR.
The difference is that you'd get a Mobil MIR with no problems and that isn't always true for SOPUS MIRs.
