I find the X-1R Octane Booster very addictive as it's really an amazing product! I love the product!

I used the Engine Flush, drove four days - 160 kilometres. Drained the sump, changed the filter, refilled it with synthetic oil and added X-1R Engine Treatment, added the Fuel System Cleaner too. After 10 to 12 kilometres, a smoother effect had begun to be felt. Days later, replaced the gearbox oil and added the X-1R Automatic Transmission Treatment. The effect on the whole car in all areas was instant, much smoother, no jerky changes and quiet.

After using the Engine Flush and Engine Treatment, I found that even when pushing 150kph, the engine is quieter than before - and mine is a diesel engine. It’s even quieter when standstill.

I used the X-1R Engine Flush and Engine Treatment on my Sorento - 2 bottles each as the engine oil capacity is 8 litres. It was good. After that, it was the Diesel Treatment. Within 30 minutes, the diesel chatter was more subdued and the engine felt more responsive.

I started my 230km journey to Fraser’s Hill from Kuala Lumpur. I filled her up with X1R’s Octane Booster and the bike didn’t skip a beat. The small bottle gave me all the power and more. Punchy power on the tap, continuous mid-range and flying top-end speeds on the way back.
