    Engine oil circulation

    Hi all, As we all know, our engines come on and go off all the time. What worries me is, when they come on, they sometime rev straight up to 2200 rpm, sometimes even more. Surely this is bad for the engine, the oil can't have time to lubricate things. I was always told never to rev the engine...

    I have had my MG3 Hybrid + Trophy for almost 9 months now, I have been very pleased with it apart from some issues with settings and would like to know if any other owners suffer like myself from not being able to turn off the annoying alerts especially ‘Your Are Over The Speed Limit’. I...

    Breakdown in France

    My cousin broke down in France and had to leave he car there for repair. Something about electronic stability control. Now it’s been repaired, she has to go and get it, at her cost. Does that sound right?

    Got an MG3 as a courtesy car today

    My HS PHEV was in getting some damage repaired that someone else caused, and I was given an MG3. Inside I was pleasantly surprised by the two screens with all the infotainment etc, very similar to the HS really. It was a 1.5 petrol and only a 5 speed gearbox which I don't think is good enough...

    Strange city vs highway fuel economy – anyone else?

    Hi everyone, I’ve noticed something strange with my MG3 Hybrid+ and wanted to check if others have seen the same. From most reviews and technical breakdowns, the hybrid system should perform best in urban conditions—lots of regen braking, electric-only driving, and low-speed efficiency. But in...

    Engine revving hard when pushed & maybe why it does it?

    I was talking to my service department boss yesterday. about this over-revving business, and he explained that the engine and gearbox are not always tied together as in a normal ICE engine, and that there is a coupling that disengages it, so when you nail it or are going up a steepish hill, all...

    Revving issue still present?

    Hello everyone, We just test drove the MG 3 Hybrid+ at the dealership today. Overall, we couldn’t really find much to fault, except for the somewhat delayed gear changes. When accelerating with full throttle up to around 90 km/h, the engine revs quite high—too high, in our opinion—and only...
