haha... got poisoned by this discussion! I went and bought myself 2 bottles!

If you all still want, there are at least 10 bottles on the counter of Caltex Centerpoint! Just got the bottles there just now.

Actually, RM35 is not cheap. It's just average price to me.

So, how's the feedback for those who have used?

Most of the fuel system cleaner works as in pour the bottle into a near empty tank then fill it up and use it till almost empty.

I used to think that pour the bottle into a near empty tank and drive it around first till almost (99%) empty and then fill it up! haha....

Actually this fuel system cleaner is used for a 12 gallon fuel tank, which is equivalent to 45l. Most of D segment cars (or some C segment) are more than this capacity. That's why BMW's system cleaner has a bigger volume!

I've used it for my scooby. It DOES give me a better throttle response which in return gives better power delivery. On FC side, there's no difference. Perhaps a little more consumption? But depends on the traffic condition, air density etc. So can't conclude on the FC. Need to see 2nd tank without this fuel cleaner.

My current mileage is 67k. Used GUM fuel system cleaner before and this Caltex DOES give more feel than GUM. Price is also 2x! haha
