update on TCP with the iswara:

knocking fully resolved, may consider to advance back my ignition timing lol
no significant improvement in response/power though (maybe still on the retarded ignition timing)

4 bottles available at Caltex beside Giant at Bayan Lepas, Penang. Bought 1 bottle to try out.

At 1st bought for RM45 after questioning them about the outrageous price (Price tag printed was RM145 lol). After 1 hour of driving I decided to fill in petrol at the same Caltex petrol station. That was when I saw the big sticker promoting techron concentrated plus for RM35 till 31 August 2014. Took a picture and went inside to question them again (I brought the bottle along as I still haven't use it). Initially the lady at the counter said maybe it is because that stock is old and the price for old stock is RM45. I told her that this product is new and it is at introductory stage, how can it be old stock? Plus the sticker clearly says it is till 31st August 2014. Told her to check properly again. After calling someone on the phone, she finally refunded me RM10.

Glad to get it cheaper but the staffs are really 

Will try it to my iswara later

Any review after using at yr 4age?

Will try it also for mine 

ok 3/4 bottles used, may consider stocking up... why?

butt dyno on the inspira seems better acceleration despite being a 9k km 6 month old car... (well technically it's born in 2012 lol...)

hmm only drove some less than 5km from station to my house, so hard to judge yet, but the throttle seems lighter...
again, butt dyno so take it with a pinch of salt.

iswara/sentra not much difference at all even on butt dyno.

so last bottle still pending the kancil which still got a week of usage to go (damn that low fc car )

went to caltex sg.nibong, penang, on a near empty tank but stock finished. poured r95 fuel & went back home:(

I can vouch for the Techron Concentrate Plus. I'm currently in the states and this is by far the most recommended fuel additive that actually works. I use it frequently on my VW and it helps improve the mileage by a noticeable amount. I use a bottle every ~2000km.

interested to try..
how to use it? never ever used addictive before...

thanks

Definitely. My detailing geeks in the states sworn by this too.
