May I know what car you are driving?

If use Petron Blaze Ron 95 it will reduce knocking tremendously.

On the other hand if your car is using old Japanese engine (80s to 90s JDM type) than you may wish to give a try to Caltex Techron Ron 95.

If either Petron Blaze Ron 95 and Caltex Techron Ron 95 cannot solve your knocking problem then you may need to use Ron 97 petrol.

I believe (maybe I am wrong) it has nothing to do with thinner or thicker engine oil.

I owned 2 modded cars one is Satria with Mivec engine and the other Accord with H22A engine which both are high compression engine and it was suppose to to use higher Ron petrol eg Ron 97.

My Satria is currently filled with Caltex Techron Ron 95 and the engine oil is Hi-Rev 15W-50 (Semi Synthetic) so far so good no knocking but it need to change engine oil at 4,000 km interval.

As for the Honda is currently filled with Petron Blaze Ron 95 and the engine oil is Qmax 5W-50 (Fully Synthetic) so far there is no knocking and the engine oil will never dry-up or evaporate therefore I only change the oil at 8,000 km interval.

Pls see file attachment of the pics of the engine oils that I am using for my Satria and Honda.

If you wish to pump Caltex Ron 95 (by using credit card) pls avoid Caltex (LDP) heading to Sungai Buloh/Kepong after the toll because there is a word "ofline" appeared in the receipt of the credit card transaction.

I wonder whether the points earned via Caltex Journey card will be recorded or accounted.

The problem with Caltex Journey card it will not shows the total points you earned after each pump.

If any of the forumer here is attached to Caltex pls bring this issue up to the Management.

I may be wrong and it look like the sound is not engine knocking or pinging but is either the ignition coil is mal-functioning or you are using the wrong spark plugs.

I wish to share about Petronas Syntium 1000 Fully-Synthetic (15W-50) and Petronas newer engine oil Syntium 300 Cool Tech (5W-40).

I have a Suprima (apart from Satria and Accord) and every morning I will warm up the engine until the temprature reaches 3 levels/bars in the speedometer before I drive the car.

Surprisingly when I used Syntium 1000 (15W-50) the car will reached 3 bars quicker as compared to Syntium 3000 (5W-40).

In short, my view (maybe I am wrong) that Syntium 3000 can take better heat than Syntium 1000.
