Can somebody put my mind at ease please
Just got my 1st report back & my lead was 32! My car is a 2010 with 40k miles(at time of sample) on it. I had ~10500 miles on the oil & 12 months. I got SC'd at 38k miles. He said unless leaded fuel or an octane booster was used, it shows bearing wear. Well, I did use Torco race fuel concentrate twice around sample time. Would that do anything for lead amounts?? Thoughts??
