Engine Mechanical problem
2004 Acura TSX 4 cyl Front Wheel Drive Manual 92,000 miles
I have a 2004 Acura TSX with 6 speed manual and about 92,000 miles on it. For some reason, my engine is burning oil. I checked for leaks and there are none. Also, while im driving, at about 2100 - 2500 RPM, my engine makes a high pitch metal grinding noise. Can they be related? My engine is suppose to take a 5W-30 and from a mechanics suggestion, I put in a 10W-30 so it doesnt burn the engine oil. Is this safe? What could be the problem?
