Naimed 5th Gear May 15, 2014 Share May 15, 2014 Currently using FP Plus once a month (30ml). The initial doze was good even for the Altis. Over the months, only pumping Caltex 95, could not feel much effect, however Engine felt much livier with the FP Plus running. Occasionally when we switch to Shell 95, we get very good mileage (improvement of around >10%) also. Link to post Share on other sites More sharing options...

Occasionally when we switch to Shell 95, we get very good mileage (improvement of around >10%) also. If pumping Shell 95 gives you >10% milage than Caltex 95 and if Shell 95 cost less than 10% more than Caltex 95 the you should only use Shell 95. However to get more than 10% better milage from the same octane fuel is very hard to do. Link to post Share on other sites More sharing options...

Earthboy 4th Gear May 15, 2014 Share May 15, 2014 (edited) from what i have read, use too much fuel cleaner will eats up the diaphragm of your fuel pump. i also understand that not all car fuel system has this diaphragm thingy. mine is one of them.

Naimed 5th Gear May 15, 2014 Share May 15, 2014 If pumping Shell 95 gives you >10% milage than Caltex 95 and if Shell 95 cost less than 10% more than Caltex 95 the you should only use Shell 95. However to get more than 10% better milage from the same octane fuel is very hard to do. The 10% increase in mileage is after using Caltex 95 for a while and then swop to Shell 95. After 2nd pump of Shell the mileage returns to normal/average, so I go back to Caltex as I feel Caltex has good balance between engine smoothness, power and FC. Caltex 98 doesn't improve anything and V-power gives bad mileage on the Altis...although there's a perceived increase in power. Link to post Share on other sites More sharing options...

Spinelli_ck 6th Gear May 17, 2014 Share May 17, 2014 Engine felt a little smoother. Still monitoring on FC. My milage is currently at 130k. Im driving a vios so dont know whether is it DI or not. Vios does not utilise direct injection. like Altis, it uses EFI. Link to post Share on other sites More sharing options...

Tommisan 4th Gear July 16, 2014 Share July 16, 2014 Bought 2 bottles of Techron Concentrate before end of June. Used 1 bottle so far. Now probably on third or fourth tank. FC used to be around 8.8-9.3 km/l. Now I am achieving 10-10.5km/l. 10% lower FC, worth it. Link to post Share on other sites More sharing options...
Kb27 Supersonic July 16, 2014 Share July 16, 2014 Techron is PEA. PEA is good. Even Subaru knows it. ↡ Advertisement 3 Link to post Share on other sites More sharing options...
