Well u got it correct at some point but left foot braking is used in manual transmission too u know.

U guys don't get what i'm trying to point out here. Left-Foot Braking is new technique to drive used even in Manuel Transmission. Do some research. (@NPP as for u Mr. I do have a license and of course it's pretty natural to have a tube light equipped cyborg among others with pure human flesh )

I think that the most logical thing to do is using the left foot because that way the reaction time to brake decreases than using the right.

I have a car with automatic transmission and I always use my left foot for braking. is it good? (my uncle screams at me whenever i use left foot to brake) what do you guys think?

thanks... But in theory combustion of 95-octane releases more pressure than 90-octane. Therefore don't you think using 95-octane on a regular engine causes to reduce the life time of the engine?

Yap.. All i could find was compression ratio, max power and etc. It says nothing about high compression or not-(well of course common sense leads me to believe it's a regular engine though) But I just need do know how to separate a high compression engine with a regular one. Can it be determined by mere cylinder capacity and compression ratio?

Thanks.. but while reading on I found out that 95-octane is used in engines with high compression. So let's just assume a car is used for highway runs and then without a doubt 95-octane is better to used as you say. But how can we determine whether it's a high compression engine or not? What is the link between compression ratio with the above?

I have a Vitz 1.3 U (2010) and the compression ratio is 11.5 :1 How to know whether it has a high compression engine or a regular one? I've only used 95-octane petrol so far. (I was told only to use super petrol by the sale I bought from) But while reading other threads I came to know that there's no performance down in using 90-octane. Is this true? plz enlighten me.

Ya ya i get it. I've searched many times and just ended up with specs like those. But recently a guy from a car sale told me told me that Vitz U grade car is equivalent to a car of an Auction grade S. Is this true?

Is there something to do with the quality? Is there any link between those grades(U & F) with japanese auction grades? Plz help...
