My car has 37,000 miles. It has been fed Shell V-Power for 98% of its life, and M1 5W-30 for all but the first 10,000 miles (5,000mi OCIs). Gas mileage is consistent, hovering between 26-30mpg depending on my leadfootedness.
Having used a Top-Tier gasoline and a synthetic oil high in detergents, will fuel additives (FP, Techron, etc.) provide any benefit at all? Are my valves/injectors/rings going to have any deposits that regular use of Top-Tier gas can't handle?
I'd rather not use additives because it might interfere with UOA results.
