Since your fuel lid say premium, best stick to RON97.

As you know in fb, i recently bought me a Caldina GT-Four. Since its a recon car, i couldn't find any references (i.e car user manuals) what's suits best for the engine. I remembered seeing a notice on the car fuel filler lid saying "Use Premium Unleaded fuel only"….does this means i can only use RON97?

Please help.

Thx.

Any update on the Diesel Euro 2M in September?

I have just migrated to common rail on diesel and with the mileage that I'm getting currently, I just look forward for the Euro 2M and could care less about all the gasoline RON, Vpower and what not..

maybe there is a conspiracy behind this or the M'sian Govt is being generous in subsidising the local drivers here….

another thing is this just shows that it is also no economical to use less additive ron92 like in shell or petronas! because 10sen different of price will make the engine less effecient. 10sen means 5.5% saving ..but you save7% as your engine more effeicient!

For me, i find out out that RON 92 can give u less milage compared to RON 97, thats why i prefer use RON 97. RON 92 can make ur engine more carbon and then less power in the end.

Even when i use petrol for Petronas RON 97, compared to Caltex RON 97, can see that i gained more mileage with Caltex, tried so many times already until i lost count.

very good strategy..it will make caltex gain the trust of the public..

by looking at the petrol pump station, i think malaysian use highest pool octane number! because more than 90% user use ron97..so strange..imagine how many billions could be save if people in malaysia use the suitable RON and all the petrol have the same additive regarding the RON number like Caltex do..

10sen for every liter oil since maybe 1996..that is huge!

RON92=rm1.70, RON 97=rm 1.80

another thing is this just shows that it is also no economical to use less additive ron92 like in shell or petronas! because 10sen different of price will make the engine less effecient. 10sen means 5.5% saving ..but you save7% as your engine more effeicient!

The price of Ron 95 is only lower than the current Ron 97 price by 5 cents.

What is the logic

As for the answer from Caltex. I think is better that we just refer to our car manual. They are just too careful with their answer[/quote]

If they don't raise the price, what's the point?

The RON 95 Slide Media is quite useful for the first few slides. After that it went more to marketing the particular fuel brand. Kept on repeating Techron name over and over again, but I don't blame them, at least some technical data to give us insight of what's is this RON thing. Unfortunately, when it comes to RON: Frequently Asked Question, there's nothing much technical is mentioned. All are redundancy and avoiding answering the question in the first place. As if it was typed by a non-technical guy. Might as well don't raise and answer those questions.

so.. is there any problem if i switch to RON95???

please help…
