Recently purchased a Honda Accord 2005 Thai Variant. I need to know the following:
1) Best Engine Oil. The car's mileage is 175K.
2) Got a check light for O2 sensor that's linked with the Exhaust. Changed it thrice because after driving for 50-60 km the check light comes back. What's the way forward? Any sensible auto electrician who understands this kind of issue of accords.
3) Car struggles while switching to 2ng gear on low rpm but as soon as the RPM goes up it gives a scary jerk. Am I supposed to change the gear oil and filter? Got the valve body checked it looks perfectly fine.
