Does not look good. Looks like V6 always eat petrol. Link to post Share on other sites More sharing options...

More cylinders (even if same cc) more surface area rubbing against one another more frictional losses more FC. All other things being the same. But the lure 6, 8,10,12-cylinder engines are hard to resist.... 1 Link to post Share on other sites More sharing options...

V8 should be screaming already. What about IL6? Edited September 11, 2019 by andrewyewkc Link to post Share on other sites More sharing options...

All other things being equal. V6 needs 2 crankshaft and cam shaft. For 90 deg V6, there is a counter balancing shaft required for end to end vibration. 3 Link to post Share on other sites More sharing options...
Volvobrick Supersonic September 11, 2019 Share September 11, 2019 V6 still has only 1 crank shaft, but 4 camshafts. And a longer timing chain/belt. All adding to more friction and weight. Only engine I experienced with 2 crank shafts was a square four in a bike. 2 Link to post Share on other sites More sharing options...

I realize the trip computer usually shows 1km/L more than my own calculation. For e.g. trip computer shows 16km/L, when i manual calculate it is 15km/L. Not sure why lol. What's your city/highway proportion? My car during 100% city is really bad, worse i got was 8km/L. Link to post Share on other sites More sharing options...

What's your city/highway proportion? My car during 100% city is really bad, worse i got was 8km/L. Wow, 50L is quite big. Mine stated is 44litre? But usually i pump about 39l to 41 Litre worth of petrol only. And it can run initially about 510km? Now it can hit 530km with 39-40litre. Now i try to "drive smart" and "drive efficient". Cos before, i made alot of unnecessary short trips. Eg, drive and park at office canteen nearby. Eat and then drive to park at B1 and go office. Or drive to nearby for breakfast or lunch during weekend, but whereas i can just walk or eat nearby. So now my highway to city proportion might have increased to 70% to 80% i hope, whereas before, it might be like just 60% to 55%. So in the past, i made more short distance drives, and that might have caused my FC to be not as good. Mine is 17inch rim, so more "start-stops" or short trips might made the engine to consume more fuel to move off from stationary. I am currently still monitoring if my FC can still improve with these improved driving habits. Edited September 13, 2019 by wangxiaodi 1 Link to post Share on other sites More sharing options...

If u are smooth and gradual on the accelerator, FC will improve. Link to post Share on other sites More sharing options...

How many litre is the full tank? 55 liters. From orange light to full tank is typically ~50-52 liters. The car is heavy, but when it gets up to speed, the drive is firm like the European marques.
