Hi All,
Few of us have experienced using Shogun Fully-Syn Oil, where we encountered worse performance than the Fastflo Fully-Syn Oil that they use under the NPMP program. U can try to search for our past discussions here. I hv switched/top-up once to Shogun, and found a decrease in power and higher petrol consumption, therefore immediately switch back to use Fastflo. Therefore recommend those under NPMP to use the Fastflo EO, no nd to spend additional top-up for Shogun.
