Hello

yesterday i did drive through a parking lot that was flooded somewhat, but didn't think other wise for a 03 ford expedition, this happened yesterday morning. The late afternoon i went to get food, no issues than!!! than today as i was driving to work, i noticed AND I EXPERIENCED THESE ENGINE NOISES FROM SIMPLE things like oil change or new filter, but in this case i am getting on my code reader

po306 and po316, i am thinking either the oil changed lube placed lied and i had low oil causing the misfire, this happened once before to low oil and a plug ford motercraft oil was used, now same issue i had motocraft oil for this cycle for the past 5000 miles, so it seems either driving that semi flooded lot  caused it or fords motorcraft oil is total bs and i ran low and caused a misfire? 

should i wait tomorrow, and see if more dry air helps , or get the mechanic  get rid of that garbage oil, I LIKE PENZOIL and change the plugs? 

 
Get rid of the oil! It's relatively cheap to get a tune up compared to running bad oil through your engine and messing it up. Then you are really screwed. And check your oil yourself to make sure you have enough in there. My husband likes Mobile 1 synthetic oil, but that's where you lose me, I don't know why he thinks it's better than another brand and I think it's more expensive.

I'm no car expert, but I had to have an engine rebuilt once because I was relying on my boyfriend to make sure it always had fluids in it. Big mistake! I'm sure you know that if you are having weird engine noises you need to get it checked out asap.

 
Hi there, chances are that water got into somewhere that it wasn't supposed to. I highly doubt the problem is related to your oil.

See how things are today, if it's still acting up you may have to change the plugs and if that doesn't work then maybe get a mechanic to give her a quick look over. 

Regards,  T..

The motorcraft oil that I used for my Lincoln was good semi-synthetic oil and was factory recommended. I don't think you have an oil issue.  Let us know what happens next.

 
it got replaced today but not sure why the mechanic put 10w40 oil when i requested penzoil high mileage oil either 5w20/30 , unless they make penzoil 10w40???? , 137,000 miles... weird??? 

truck runs good again <3

  5. Realbenzeyes @ Realbenzeyes: I’m salty myself, being an Ohio state fan, but Miami is winning by the smallest margin. Indiana going to be hard to beat
  6. M @ meepmoopmeep: I’m salty about the SEC being eliminated but good for Miami. it was a well fought game by both teams
  7. M @ meepmoopmeep: Imagine being a 10 seed barely squeaking into the playoffs becoming a cinderella team
  8. M @ meepmoopmeep: I think they can beat Oregon, but Indiana is too good
  9. Realbenzeyes @ Realbenzeyes: Who thinks Miami stands a chance vs either team (Oregon or Indiana) my bet is Indiana but you never know

  15. Thoth @ Thoth: @sporidicus honestly depends on the mag. Read read read read the forum
  16. Thoth @ Thoth: CFP needs more of an NBA or MLB playoff structure but that would be hard to structure. Divisions inside Leagues
