I have a Ford V-10 gas engine in my 2012 motorhome. I have 37,000 miles on if and change oil regularly. I'm planning a cross country trip of over 3,000 miles in 45 days and want to use your product on this trip to clean injectors, spark plugs and upper cylinders valves and piston surface. My question is my engine runs about 7-8 mpg of fuel and I have a 80 gallon tank. By using a high rate of fuel as I do will this have bad effects on the engine being so much fuel usage in a short period of time?
