Replying to: jt8 (May 20, 2009 3:06 pm) Hi all, I have a 2008 Acura MDX with similar oil consumption issues. Starting at about 4K miles, I got the warning indicator for oil level and oil pressure. I took it to the dealer and found a service advisory that showed certain VIN's having a defective oil pressure sensor, mine was not in the vin range, but Acura replaced the sensor regardless. Now, at about 9500 miles, I got the same warning indicators and took the vehicle back to the dealer. I was told the oil level was at about 3 quarts, so down almost 2 quarts over 5K miles. Now, I understand the party line is you could loose up to a quart per 1K miles, but literally in the course of an oil change, that would mean you would loose the entire amount of oil originally inserted at the last oil change 4.5 quarts. This seems a bit unusual to be that low on oil with basic city driving in such a short amount of miles. The dealer first tried to blame the use of Mobil 1 Synthetic oil, claiming that is not recommended for the car. Per the manual, as long as the synthetic oil is API certified, which it is, and 5/20 weight, it is perfectly acceptable. So, I am curious if anyone has any ideas as to why the engine is using so much oil? The dealer is doing the same pressure tests, etc.... as the original person above, but I am hoping somebody could help point me in the right direction, as I think they will come back and claim it is normal.
