Hey guys I have a 06 m7 and about a year ago I turned out my oil injection rod to run the sled a little leaner, cause I was burning almost an entire tank of oil to a tank of gas, after I adjusted the the rod I marked the oil level in the tank with a maker then ran it all day and then added gas and oil then did the calculations and it was around 40:1 sled ran awesome like this for over a year until Saturday I went through 2 sets of plugs and over a tank of oil what would cause the sled to all of a sudden drink a ton of oil like this ? Any ideas
