I never shut it off until the temp gets off the "C" and I burn 93 octane along with I use 5W20 Castrol, a Mazda oil filter with 3,000 miles in-between changes. I drive my car mostly on the inter-state or on highways. Yes, I have changed my oil twice in 30 days sometimes.

My car has 67,000 miles on it, so I drove 58,500 or so miles on a set of plugs. I actually thought my car had close to 30k on it when they were replace during the recall. I know I should have been paying more attention, but I didn't and I will change them at 97,000 next time. I did the coils and the wires, because it made sense to do it before I had any trouble. I had no corrosion on the coils either.

Tell me what you see? From right to left in the first picture is Leading, Trailing, Leading and then Trailing

I did noticed that the Trailing plug on the front egine/car was full of oil. This was the only plug that had oil on it. I am guessing that is where the missfire code is comming from. the leading plug in the same camber was dry. Any idea's?
