Mileage / Speed Correction

My Alphard`s stock tyre is 205/65R16. It will give the tyre circumference dimension at 2114.0mm. My aftermarket tyre and rim is 225/45R18 with 2072.5mm circumference. Previous post, managed to achieve 689.2km per full tank with 225/45R18. The actual/correct mileage is re-calculated.



One complete cycle of stock tyre will give 2.114m distance compared to aftermarket tyre contribute 2.0725m distance.
With stock ECU, stock tyre (205/65R16) will have - 326,395.5 complete rotation.
Therefore my actual distance is calculated by 2.0725 X 326,395.5 = 676.5km.

With maintaining about 110km/h along the highway which was actually 2% faster, actual speed is re-calculated then.
110km/h X 98% = 107.8km/h only!!!

That`s why i felt 110km/h for Alphard is not right. Hahahahaha...
That mean for my Alphard, to maintain actual 110km/h, speedometer must indicate 112.2km/h. Ermmm, not much difference honestly. Opted to maintain 110km/h indicatated by speedometer.

Latest FC for my ALPHARD

On 30 Oct 2012..

Going back to Parit Raja after spending AidilAdha day-off in Jerteh and Pendang.
Take PLUS highway all day long. From Pendang (Kedah) entrace to Air Hitam (Johor) approximately about 642km and normal road about 47km. (93% - expressway).

Pumped in Petronas RON95 about 59 litres priced at RM112 at Pendang Petronas Station.Normally i used Esso RON92 for daily use. Because there is no nearby Esso Petrol Station near Pekan Pendang, so had to pump in Petronas RON95 instead. As for my normal practice, i would re-fuel at R&R Seremban. This time i decided to continue journey without re-fuelling, just to measure what is the maximum achieved mileage for full tank gasoline on Alphard. Hopefully my Alphard would not run out of gas before reaching home. hehehe

Below were driving conditions:

1.   Avarage speed - 110km/h along PLUS Highway
2.   2 adults + 2 children + about 40kg luggage
3.   Wheather : 60% dry condition, 40% wet surface road
4.   Stop at R&R Taiping about 40 minutes with idling engine
5.   Stop at R&R Tapah about 30 minutes with idling engine
6.   Stop at R&R USJ about 30 minutes with stop engine
7.   Stop at Nasi Ayam Haji Ali Parit Raja about 15 minutes with idling engine

Additional car conditions:

1.  Rim 18" with 225/45R18 tyre Bridgestone Potenza R001
2.  Mobil Super2000 Semi-Synthetic engine oil
3.  Full tank Petronas RON95

I managed to achieve 689.2km per full tank....
