Filled the tank today and realize my mileage increase to 31.73MPG~~ this is like a 13.5% improvement to my originally 28 MPG, or 6% more to my gain in the first Eco-driving tank.
I didn't do anything specific in addition to my effort in the first tank
I guess the 6% gain this time is due to:
- better use of DWB and DWL
- improved grill block which has a smoother shape and lighter weight?
- More efficient engine using 95 octane petrol
Another important factor would be:
My last 80km driving was on one of those "temporary tires" you would see on a Japanese car... it's unfortunate that I had a nail puncture on one of my front tire last week and replace the wheel with the spare cheap looking temporary tire, which is only 125mm in width! (compare to my other 195mm wheels)
It reduces the rolling resistance so largely that I can easily feel the difference when coasting. I guess one can achieve 35MPG+ easily by using 4 of those temporary tires.....(it would be quite dangerous though...)
What worries me this morning is that when I arrived my workplace, I opened the hood and feels like I am facing a oven fan....it is so hot in the engine room....and neither of my two fans is spinning! it is normal?
My temp gauge doesn't seem to report any over-heating, but I swear I smell some plastic this morning....
I am considering reduce the grill block from 75% to 50%, any thought?
