You cannot use pre-pay Oyster on South-West Trains (or on most other
National Rail services in London), so the only part of the journey
covered by Oyster is the bus and tube journeys. That comes to £5.90,
which is well below the £8 cap for peak-time travel in both Zones 1-4.

You would come under the Zone 1 cap as all your tube use is in Zone 1.
Bus journeys ignore zones and are included in any capped tube price even
if the bus journey was in a totally different zone to the tube cap.

Not sure what that makes your cap without looking it up.

The Peak Zone 1 cap is £6, so £5.40 (sorry, its not £5.90) still
wouldn't reach the cap. Thus Oyster remains almost 50% more expensive
for the journey I have described.
