Have just purchased a1989 Californian motor yacht. The previous owner only used the saddle tanks when traveling. When purchased the main tank had approximately 200 gallon s of fuel and not sure how old. The engines are Detroit Diesel 671T. I've had the fuel tested and results show the sulfur content is 950ppm. Does anyone know if it would be detrimental to the engines to use the fuel with this amount of sulfur?
Thanks in advance.
