So I was reading through these post and decided to add MMO to my engine and gas. 3/4 quart in oil (drained 3/4 quarts) and 3 ounces in my tank right before I put 10 gallons of premium in. My car lost a ton of low end torque. My take offs were slow af. My car seemed to drive smoother... but either I was paranoid or it sounded just...tamed down. I just did a oil change with 5w40 and decided it was a bad idea. It may of just been it diluted my 93 gas down too much, idk. Just felt like sharing.
OH and can we make it a know thing that 7 quarts of oil is what fills our cars up not 8!
