"I replaced my 10 year old ----- Platinum +4 spark plugs which I was still getting 38 MPG highway with over 225k miles. After replacing with E3, my MPG fell to 32 MPG highway. Disappointed to say the least. I'm returning and going back to a new set of +4's."posted by: MJ on December 19, 2011
"Would have been easier to install if my car's spark plugs were more accessible."
