I 2nd all that DH just said & will add My Recipe >
For an H2OBoxerEng' ~
Conventional/Dino 5w30 ~ 1st Hour ~ then drain it 1000-3000RPM ~ Trying not to stay @ any 1 RPM for vary long
Conventional/Dino 5w30 ~ 0 - 600 Miles ~ then drain it Not over 4000RPM ~ Trying not to stay @ any 1 RPM for vary long
Conventional/Dino 5w30 ~ 600 - 1200 Miles ~ then drain it Not over 4000RPM ~ Trying not to stay @ any 1 RPM for vary long
Conventional/Dino 5w40 ~ 1200 - 2000 Miles ~ then drain it Not over 4000RPM ~ Trying not to stay @ any 1 RPM for vary long
Conventional/Dino 5w40 ~ 2000 - 4000 Miles ~ then drain it Not over 4000RPM ~ Trying not to stay @ any 1 RPM for vary long
Conventional/Dino 5w40 ~ 4000 - 7000 Miles ~ then drain it Not over 4400RPM ~ Trying not to stay @ any 1 RPM for vary long
Conventional/Dino 5w40 ~ 7000 - 10000 Miles ~ then drain it Not over 4800RPM ~ Trying not to stay @ any 1 RPM for vary long
FullSynthetic 0w40 or 5w40 ~ 10000 - 14000 & every 4K after that until OilPressureGauge tells me I might want to think about a *w50
or an Eng'Rebuild
Switching to FullSynth Earlier is OK if there is Little to No Oil Consumption & You are planning an Extended Run with a Load ~

Keep an eye on oil consumption. Especially with some of the aftermarket cylinder sets broken rings happen. Avoid lugging. The WBX is a short stroke engine that makes little torque. It needs to spin to get work done. Part of break will also establish that carbon ridge at the top of the cylinder.
