                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 ~

                                                                                                                                ORR ~ DeanB

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.
