Grand Espace Fuel Consumption


Fuel consumption is a popular issue or subject to be discussed.
our "lowered" Grand Espace with full load (2 adults +
our 6 kids + baggages)

My previous Renault Espace III 2.0 8v petrol, in general can reach (full tank)

  • 90% Highway (average 110kmh) : about 700-750km
  • Mixed : about 550-650km
  • Most city : the worst.. about 480-550km only

When I used my existing Renault Grand Espace III 2.0 16v petrol, I was suprised that I cannot get better fuel consumption than the previous unit. Theoritically, the 16v engine is more efficient and therefore, should also be quite more economical than the 115bhp 8v (the 16v has 140 bhp.. when its new)
Caltex petrol is my new favourite. It really improve
performance and efficieny of my Espace engine.
After some minor improvements and tweaks, Alhamdulillah I can get extra mileage; which about 700km+ for a full tank of petrol, consists mainly of 110kmh highway. The minor tweaks are

  • Pumped up the tyres to the recommended pressure (because it is quite under inflated before) 
  • Use different petrol. Previously I dont care much. Now after 3 full tank of Caltex Techron 95, felt the engine more responsive (especially when climbing hills) and that maybe helps to reduce engine strain.
  • Repair the air hose. The engine air hose which channel air to the engine is actually has some tear, therefore the engine is also sucking hot air from the engine bay thus reducing the engine efficiency. (Colder air helps improve engine efficiency in hot & humid countries)

The air hose was "repaired" with a masking tape.
The original hose was soft and tear easily.

That's all the minor tweaks done and it really helps. Maybe if I only drive an average and consistent 80-90kmh, and slow acceleration; I am quite sure the fuel consumption will further improved. But frankly speaking, driving the Espace at consistent 80-90kmh, is a very challenging thing to do, as you feel the vehicle is so slow.. like you want to sleep la.

So, happy driving and take care.

  1. I absolutely agree that Caltex is 'the petrol' for Renault. My Scenic 1.6V cruises with great power on Techron but not so much on others. Happy driving...

  3. Hi Zikri,
    For the holiday season travelling, I tried Caltex 95(first time using) on my Espace 16v, I felt there is signifigant diffrence in acceleration and engine smoothness. So far done about 800km burning Caltex.The other 2 brands I've used were Petronas & Shell, not much difference btw the 2. My espace air hose has been replaced using a air hose fr a lorry, solid.

  4. Lee, thanks for the comments. Hmm.. but the problem with Caltex is that they dont have many stations la. Sometimes I need to re-route in order to fill up with Caltex petrol.

    Intended to use the RON97 but due to cost issue (ye la, RM1 difference per litre, if full tank, extra about RM70.. that's a lot)
