I used to work at a BMC Dealership back when British sports cars were real popular. We used to advise everyone to avoid Shell gasoline, because at the time it's usage would create large fluffy tan colored deposits on the exhaust valves. Left long enough it would impede air flow.
The current fuel injection systems and the current engine operating tempratures keep the A/F ratios lean enough to minimize build up.
