My 2012 CVT is consistently averaging around 43mpg - Fuelly.
90% urban driving.. very hilly...
Tipped in a full bottle of injector cleaner last fillup (car has done 45k miles) and appear to be seeing slight improvement - maybe 1-2 mpg. But it will take 6 months to tell if a blip or not..
That's mighty impressive, my 2012 CVT gets around 30-35mpg in urban driving, not sure what I'm doing wrong because I take it easy and the revs virtually never go over 2000rpm and hover somewhere between 1200-1400rpm.
Can you please explain how you drive your CVT for best fuel economy, say from pull off to the next traffic light stop?
First of all I diy service.
Car is standard but all brakes work without ANY dragging, the wheel bearings are OK, the oil and filter are changed every year AND the air filter is clean. Tyres pressures checked weekly
These are all essentials. Car has done 45k miles. Used on long 100+miles motorway journey twice a year, No other motorway travel. Michelin Cross Climate tyres with 15k miles on ..
We live on a 2km long hill which rises 200 meters. We are 400 meters along it from the bottom at approx 40 meters height. A 30mph limit but impossible to drive further up faster than an average 25mph (Very twisty with blind corners - lots of crashes (including a Defender half way up a tree)
Starting from cold:
MPG from display
Going uphill : after 1 mile (at top hill), engine light went out after 500meters . 15mpg on display
Going downhill: after 1 mile - downhill then flat engine light still blue
I drive out of our gates and go downhill with a cold engine After 2kms of driving on the flat, engine temperature light still blue. 34mpg on display.
I usually go downhill as it is fastest way to shops.
All my journeys are 30mph limits except a 3 miles section dual carriageway which is 50/60mph.
I tend to drive outside rush hour.
I accelerate gently. Roads are hilly so coast down hill at 30mph with minimal throttle. Accelerate as little as possible uphill consistent with doing 30mph (I do not dawdle)
I anticipate traffic lights. And roundabouts. I only stop when I have to - especially roundabouts.. I slow down but if clear do not go below 25mph.
I do not brake hard except in emergencies or nutters deciding to change direction without warning.(35-40k miles from front pads).
On flats I try to drive with Economy light (green) showing.
As it's a CVT gearchanges are imperceptible so I try to drive as smoothly as possible - like a chauffeur.
When I park, all manoeuvering done when engine is warm (when I arrive) so less moving when leaving (engine cold).
When engine is cold .. and blue light on, rich fuel mixture so minimise acceleration - except when leaving drive as blind exit.
No tail gating .. too risky and too much braking.
On fast roads use lorry slipstreams to help acceleration.
Calculate mpg each tankful using Fuelly so much more accurate than display. So any changes noted . Sudden drops could be cold weather or a fault.
And every month use 3,000 too 5,000 rpm for at least 5 miles on dual carriageway to clean engine and (original ) plugs..
Standard Sainsbury 95 octane petrol.
If I just drive around town with no dual carriageway driving deduct 3-6 mpg.
If its is rain and and windy -2mpg
I averaged 36mpg one tank when we had half a meter of snow in 2013.(not fun on Dunlop Energy Savers on hills)
My Fuelly name is madasafish 42.8mpg over 8 years. Fuelly.com
