I do know someone that had some high fuel in their OCI after 12,000 miles. Also lost about 2 quarts of oil which was higher than normal and the viscosity of the oil did increase. Added two bottles Amsoil PI 2 in a 37 gallon fuel tank. Oil consumption is back to normal with no oil viscosity increase.
