hi pple,
Bought the Power-Z during the July MegaMeet '08 to see whether can FC be improved. Here's the result for 6 petrol tanks before and after Power-Z:
Car: Latio Premium
Date: Oct 2007
Modification: None, all stock, except for spark bridge
Travel Pattern: 30% Highway, 70% normal road
Tyre Pressure: check & pump every 2wks, Front: 245, Back: 235
Petrol: Caltex 95
FC: abt 12km/l
Without Power-Z
===========
1) 450.5km @ 36.848l => 12.22km/l
2) 458.6km @ 38.018l => 12.06km/l
3) 441.0km @ 38.058l => 11.59km/l
4) 437.0km @ 37.849l => 11.55km/l
5) 445.9km @ 37.562l => 11.87km/l
6) 482.3km @ 38.310l => 12.59km/l
========================
2715.3km @ 226.645l => 11.98km/l
========================
With Power-Z
=========
1) 447.8km @ 38.075l => 11.76km/l
2) 406.8km @ 35.072l => 11.60km/l
3) 435.4km @ 40.081l => 10.86km/l
4) 476.3km @ 39.434l => 12.08km/l
5) 495.1km @ 37.079l => 13.35km/l
6) 497.8km @ 39.056l => 12.75km/l
========================
2759.2km @ 228.797l => 12.06km/l
========================
The result shows that there is not much FC improvement with Power-Z. The Power-Z cost S$30.00 for 6 bottles of 50ml (S27.00 with 10% discount). The FC needs to improve by 2km/l or more in order to justify the usage and cost of Power-Z, which did not happen in my case. Think I will give Power-Z a miss for now... For those bros and sisters who are trying out the Power-Z, please feel free to contribute your findings and feedback. Thanks!
Next Topic: 20k servicing
================
I'll be going back TC for my 20k servicing. I have changed the engine oil @ 10k servicing, using Amsoil 5w-30. Do I need to change the engine oil again at 20k servicing? What type and grade is recommended for 20k servicing? Please advise. Thanks!
Lastly, if you've any suggestion to improve the FC, please feel free to comment hor
