Nothing wrong with the GTX Magnatec.The oil happened to be a cheap Castrol GTX magnatec. If I understand correctly, it should not affect fuel levels? Better oil should have just maintained the viscosity better.
Possibly more relevant fact was that I ran only 87 gas this time, as a low interval experiment
Switching to 91 and AmsoilOE, will check again in 3500.
Of course it will affect the oil level. If nothing else changes, the volume of liquid in the sump will be 5% greater.
Better oil has nothing to do with the viscosity of the oil & gasoline mixture. Dilution is dilution.
91 AKI & Amsoil oil is money spent that is not addressing the problem with this engine. The possible causes of fuel dilution are stated in the report. The cause of the dilution in your engine needs to be found and fixed.
I think the high tire inflation pressure is to prevent bouncing and possibly loosening the lashings while aboard the ship. A couple of weeks on a ship's deck is no different for flat spotting that two weeks stationary in a dealer's lot.
