also the knock will gone after you use 95 sometime cause the ecu will retard the timing, and this will reduce the knock. this will reduce the engine performance.

From theory, it won't, cause retard the timing will make burning less efficient and the unburn petrol is good for cooling the engine. When timing retard, engine performance will be drop.

In real life maybe the knock sensor is not working, and running the same timing with difference fuel will make the engine ping and run much hotter. so it will make the cooling system more load / pressure.

I find that fatty car very hard to listen to engine ping especially A/C on with windows all closed.

nah, compare to camry, fatty is still far behind in sound proofing.

I think the darm rotary A/C compressor make too much noise.

If you look at motortrader's list of vehicle can/cannot use ron 95, our fatty are under the 'can use' list. However for maximum performance it is recommended that we use ron 97 and above.:burnout:

comparing 2L with 2L the camry got more ump. i have no chance to test drive the 3L camry so can't comment on that.

in motortrader, http://www.motortrader.com.my/NUS/articles/article_1977/page_m.asp below the comment.

"For the Cefiro 3.0, Murano, 350Z/370Z, RON97 is recommended for optimum performance. For older models such as the Sunny 130Y, Bluebird, Altima and AD Resort, RON95 can be used"

I still think the camry handling and performance sucks (b4 this latest model) as compared to the fatty.

'Ron97 is recommended for optimum performance' does not mean ron95 cannot be used. If you use Ron97 your vehicle will perform better only mah.... That was what i understood on the statement above. rite?:biggrin:

If the engine knock sensor is working using ron 91 also no problem, cause the engine will retard the timing, and this will make the engine work but performance is much reduced.

When the knock sensor is not working or not very good condition, engine will be overheat and lots of problem. that is the risk.

Yeah, i guess the knock sensor has its limits also. I am now sticking on ron97 or higher for my fatty.

Anyways , I must give thumbs up to the camry's engine reliability whether old or new model. They rarely give problem like our fatties ie; engine jerking rough idle , tps out of calibration, afm faulty, etc. If even when there are problems, usually they are easier to diagnose and fix which give the owner less headache.(time and money$$$)

I drove frequently to Pengkalan Hulu, Perak. In case u guy dont know, it further north from Grik, Perak, and just next to Betong Thailand border. I took my A32 thru all those corners high speed, up to 110 or 120, and the car still quite stable although the body tilt quite noticeably. Tires screeching when rolling on road marking paint makes me a bit scared to go step on harder. Perhaps it's due to my Michelin XM1 grip not so good.

Also taken this car up the Jelapang - Kuala Kangsar tunnel winding road, overall very stable and felt well-footed.

thanx for the advice...

actually i'm quite familiar with this road, that's why i dared to go at this speed. I travel almost weekly up and down to KL, that's why the car clocked to 400k km so fast

Anyway, saw another Perak registered 30GV driving more aggressively in this stretch, maybe some mod on the suspension already.
