Engine Pre-Detonation Gone with Caltex Platinum .. (Long time Shell V-Power user & fan)

**Dezaremos** · March 15th, 2018 11:20 PM

Car is Corolla GLi 4afe 1.6 ...

Notice late last year everytime I suddenly steps on the gas pedal, engine is pinging at around 2000-3000rpm and sluggish acceleration .. I've been using Shell V-power always ..

I figure maybe because of carbon build up due to short distance driving from home to office ..

Pero diba may carbon cleaning agent ang shell vpower ???

So I remembered Caltex's Techron cleaning agent that has been getting good reviews abroad ..

I filled up a fulltank of Caltex Platinum .. And on the 3rd day of using it the engine pinging or predetonation is gone and the acceleration is superb .. the advertise is 1 whole full tank will bring back the engine performance to optimum level and mine just took 3days and an almost 1/4 of the full tank ..

I guess the cleaning agent of Caltex is better than Shell .. Maybe Techron is the real deal ..

can you please or somebody here enlighten me how does the cleaning goes? because as far as i know once the fuel gets inside the combustion chamber it detonates immediately, so how is it possible to clean the surroundings when its gone already in micro seconds?

in the few microseconds that's allowed it, it loosens the deposits daw.
more than that, google doesn't offer much more.
i suppose the answer is in the complicated chemical publications that the public does not have easy access to...

the article i saw says the chemical is not unique to caltex; the active ingredient is available in more concentrated additive form in the market.

Remember that the fuel spends a whole two cycles in a four-stroke engine (intake and compression strokes), so technically the fuel spends half the time in the combustion chamber at any given moment the engine is running.

Consider this. With the engine idling at around 800 RPM, each cylinder will be injected with fuel 400 times a minute, or around 6-7 times per second. The repetitions alone would allow the cleaning agents to work. What more if you're cruising at 1,800 RPM or higher.

Same with what happened with our car... been using Shell VPower and then because of lower prices, went for Caltex Platinum... and i immediately noticed the improvement. Less sluggish and smoother acceleration... then also got better fuel efficiency.

Could be the Techron too... but a lot of people are firm believer in Shell as the top notch fuel.

I just feel Shell has better marketing. It's logo with the white, yellow, and red color scheme is certainly brighter and more attractive than its competitors. With names as Nitro plus and Nitro Plus Racing, who wouldn't want to put their fuel in their car?

came from petron years back due to the fact that M.I. was telling us to fuel up with 97-100ron..tried using caltex..no knocking problems whatsoever..
