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.
I concur to that. We have to admit it, for high compression engines like the honda B, H, F and K series, you would definately feel the difference on using 97 Ron engines. Lesser so for non performance cars. The feel would be different in terms of knocking (as discussed), a more smooter and quieter engine and better performance. My friends on the K series type R engines swear by Caltex Ron95. They said that the Caltex 95 is the best alternative when there is no Ron97. I am a ardent supporter of Shell fuel but whenever I pumped Shell Fuelsave 95 on my SSS, the engine knocks. So after recommendation of my friends, I tried fuelling up with Caltex 95 and it does make a lot of difference. There is still knocking, but much much lesser compared to Shell 95. Only issue is there are not many Caltex stations to begin with. I have not tried Petron yet. Maybe I should try once and see if there is any difference.If use Petron Blaze Ron 95 it will reduce knocking tremendously.
