I replaced recently the spark plus in my 2003 DI , according to Hanes opening of the Sparks can be .048 to 0.056 so I put NGK platinum .052 opening. But I noticed that im using more gas since I replace them. Normally I had 325 miles per tank but now I got 295 only. My driving habits are the same. Have somebody had the same issue or a Similar experience?
