[cuscostrutbrace]

My ex-car Subaru goes well with Esso 95...Shell 95 and Petronas 95 no good,never tried anything else.

ive been using only esso for past 3 years+... cant get esso only pump shell or caltex just enough to reach an esso...but i usually plan my routes and my FC enough to reach an esso. i used this petrol on so many engines, all responded well...

wo..wo...
i don't think this thread is for discussing about fuel... i'm just putting them as example...
no matter what the thread owner use, it could also coz it's the nearest fuel station...

so what ever fuel you use, just check back and change the timing accordingly so that there won't be any knocking...
unless you have other things that can be adjusted, like FPR or piggyback etc...

Full load = more knocking, less load = less/no knocking.

do some adjustment to your distributor (retard) to solve the knocking noisy if wanna use 95RON

Cannot la wei. Meaning when I carry full load, I get down, open the bonnet adjust the dizzy & then when all the passengers get down I adjust the dizzy again meh ?

Like that very troublesome le..

My engine before this got knocking esp. hot weather,,, after tune by mechanic using timing light (timming around 10-11 degree) + CAI ,,knocking problem reduce a lot,,,

I think it depends on the petrol quality also. before they introduce ron 95, I m an avid user of Shell, but after 95 is out, i will experience knocking on my car when fill up with shell petrol. but, when I use petronas, the knocking is a lot lesser. when use 97 petronas, no knocking.

I don't buy Petronas for some reason....

If I use colder rate spark plug, will it reduce knock?

 

[pcmoddingmy]

Yes, I believe colder plugs will reduce knocking as well.
Also read somewhere that using high cams with longer duration will eliminate knock as well.

I having same problem knocking. This happen after top overhaul change piston ring and bearing conrod. Im using trd metal gasked 0.8mm. Distributor cant set more than 10 degree. If I set 10 degree knocking will occur. Any sifu can help

I think it the fuel in Malaysia making this knocking problem. With 95, I had to very2 slowly open the throttle to minimize the knocking. With 97, I can open hard, but if too hard, then the knocking will start....

But with 100 and 1++, I can do anything without any knocking at all. Plus, I can get 180km/h in third at only 4,000rpm and still get 14km/l. 20v not lagi best, but best giler.....

i don't really get it. how can you get 180 on 3rd gear and 4k RPM. fuel change doesnt do a thing to the gear ratio. my car, 120 on 5th and already 4k RPM. i get around 10km/l
