Like to have some feedback from those using Mach 5 or Synthium 800 for Preve turbo.
Why?
I am thinking of changing from Synthium 1000 to either Mach 5 or Synthium 800. Main reason is, my car mileage and speed are rather low. Only 10,800 km after 10 months and my highest speed is only 90 kph. Average speed is only 25 kph.
Thanks.
Re. Synthium 800 vs 1000. I don't know about others but in my case, for the Preve Turbo I feel the car actually performs better with Synthium 800 than in Synthium 1000.
I have used Synthium 800 for the 1,000km, 10,000km and 20,000km services. For the 30,000km service, some of you might have known - the Proton service advisor had taken me for a ride, giving me the Synthium 1000. (He mentioned the Synthium 800 cannot be used on the Preve which after clarification with the customer service I was informed this is not true as Synthium 800 can still be used on the Preve Turbo). I don't know if it's due to the engine oil or something else, but with the Synthium 1000, now the noise from the CVT/engine during acceleration is louder. Acceleration appears to be a slightly draggy. The differences are not exactly huge but the noise from the CVT and/or engine certainly is louder than before.
I will definitely switch to Synthium 800 during the 40,000km service not only because it is cheaper, but it works equally well if not better.
I am not sure about the experience from others though but in my view the Synthium 800 is better than the 1000 for the Preve Turbo.
