I use 0W40 (Mobil 1), not really for the viscosity but because it's the
only oil that stops my HLAs rattling - Castrol Edge 0W40 didn't work at
all, and nor did their Magnatec 5W30. Not a problem on newer Mazdas
with solid lifters, obviously.
You can put 0W40 in 99% of cars made - a notable exception being some
1990s Fords, which must use their specified 5W30 to prevent valves
sticking - although it won't give the very best fuel economy.
