Hi guys,

I have had my Acura Cl 03 Type S AT now for about 4 years and 30,000 miles and have very closely followed the maintenance schedule in the owners manual yet a few weeks ago when I sent in my oil to Blackstone laboratories for the first time results came back with several times more than the normal amount of aluminum, lead and iron. Any of you guys had this issue? I do drive my car hard from time to time, but only after properly warmed up and generally for short periods of time on one of my favorite roads. The rest of time I am very easy on the car and generally don't go above 2500rpm. I can't imagine that would be the cause of excessive wear to bearings and pistons unless there is another issue. Like to hear what you guys think! Results included below.



Comments: Your Acura's V-6 engine may have a couple of issues to deal with in the near future. The high
aluminum (from pistons) and lead (from bearings) show excess wear at the both the upper and lower ends.
Iron can be from any steel part - cylinders, steel shafts, valve train, etc. It's good that you've changed this oil
out. We didn't find any evidence of antifreeze or fuel in the oil. Even though the TBN is still good at 3.3, we
don't recommend running any longer on the oil. One or two short oil changes should help reduce wear.
Check back for another look and to start trends.

Thanks,

 

What kind of oil did you use?

I'd post this up on bobistheoilguy and get thoughts there too, very knowledgeable guys over there.

 

I use mobil one high milage full synthetic recently and the car has had some sort of full synthetic oil its entire time I have had the car, as well as the previous owner. Also that a great idea to post over on bobistheoilguy. I will have to do that!
