Hi, I also own an Optra, but is 1.6 Auto. Recently, there's this problem of the RPM going above 1, sometimes even 2 at P & N position. Sent back to agent to reset, but problem came back after 1 week. They have rectified the problem again yesterday, but I suspect it may happen again.

This is because the RPM needle is always slightly higher at P & N though not above 1 when compared to D, R,1,2 positions.

Can anyone advise whether this is natural or is there really some problem which I need to consult the service centre?

The car has a superb handling. To reduce the tire noise, I suggest use 60series Michelin Tires. A tire lesser than 60 series caused any car to have stiff handling. A tire with Temperature A grade is sufficient enough for the car as it is equipped with traction controlled system. While a temperature AA grade means a tire has more traction and only long last 10 months.

Engine oil is important for any car engine. Try to change a proper engine oil first. The other way to reduce engine noise is to use a suitable coolant and distilled water. Since it is an Australian Holden engine, the engine effect is different in Australia and Malaysia. Compare the climate between two countries and configure it. For example, the proportion of coolant maybe different or type of engine oil is different. Both country has different altitude and longitude. Just like turbocharged engine respond better in high altitude. That is why Japan has lot of turbocharged models.

Anyway, the workshop should know better.

Most of the comments on fuel consumption above thus far is related to the Optra 1.8L model. Does anyone have fuel consumption numbers for the Optra 1.6L model (preferably in km per litre)? Thanks much!

I am driving the Optra 1.6A. My wife drives it most of the time, about 60 % on highway, and 40% urban driving. Fuel consumption is about 20% higher than more efficient Japanese engines - reckon about 10.5 to 11 km/litre.

As for high rpm; I got the problem, but was resolved. What happened: I press accelerator when starting. Engine control unit then use this as rpm for subsequent starting. Technician reset electronically.

Overall, happy with car - different from lighter cars - stable at high speeds.

I bought my Optra 1.8 6 months back. So far so good. Smooth. The gearbox is not respond fast enough. Need to press on your brake, shift it to 'D' then release the brake and accelerate. I guest changing a higher grade ATF gear oil will help. But more expensive. Remember to let the engine warm up first for 2-3 minutes before driving it. May save your repair cost. The fuel consumption is depends on an individual's driving habit. Maintain the rpm at 3000 at 4th gear save you lots of petrol. Its noise reduction system is just fair enough and is not good as it was advertised. Overall quality is good. Best value mid size saloon car in Malaysia. But hardly can see any spare parts around. If the original rims are 16-17", front grille same as the Canadian style Optra, and a fuel consumption indicator (liter/100km), It will be no challenge in its category. Hope I can get a half cut from the half cut shop soon.

Is the top speed 180km/hr? Honda Civic 1.6 v-tec can reach 190km/hr.

19 AUG 2005,22.56 I bought Optra 1.8 LT in Oct'04. The car stops after I start it about 4 times a week. Chev's service is to change the garebox. The same occurs again within a month. Chev changed a battery. The car stop while I drive on the road in Aug 29, 05. Chev change the benzene bump. I fear I will not survive. I would very appreciate for any advice.

You guys are so lucky! We have a 1.6L optra and my gosh it really drinks and even gargles gas! City driving is at 5-6 km/l and that's with no traffic. I don't even press the gas pedal too much just to save on gas. I've found out that aside for having a heavy body, the air-con compressor runs continuously and only at high revolutions or low/high freon will the compressor cut-off...that means added load to the car. I asked our dealer to give me a good reason why the design was made like that, but what they say is..."it's for the climate control". My question is "does it have one?"

Hi, I have had many problems. The cabin noise and fuel consumption are not acceptable when compared even with old cars. Also the driving power will drop when starting the air conditioning.

Some tips to lower your fuel consumption.

- Inflate to correct tire pressure -- approx 220

- Check your wheel alignment

- Be gentle with your right foot.

- For an Optra, the fuel tank is not full even after fuel pump auto cut off. You can still pump about 10 litres into the tank. This is due to the design of the tank.

"I have a 2007 Optra LT and found this out when I hooked up my GPS system and there was a difference of 3 to 9 KMH."

If this was a standard hand-held GPS, it is not giving you the pinpoint accuracy you might think. A better way to cross check the accuracy of the speedometer, and by definition the odometer, is to use the highway markers and check that they are reading one mile apart on the odometer. Using a stopwatch, doing 60 mph you should pass each mile marker at 60-second intervals. Unless you have a very expensive, survey-grade GPS, it is only truly accurate to within about 50 feet regardless of the "1-meter accuracy" claims on the box.

The same goes for checking speed -- the GPS will be pretty close, usually within 3 mph, which sounds about the range that you're reporting, but they don't have the capability for exactness. It's not the car that's inaccurate, more than likely it's the GPS.

Just changed the rim and tire size. It will do.

2nd Jul 2007, 05:17

Fc about 9.5-10.0/L in 60%city and 40% drive. a bit wind sound though right side when speed >100km.

2nd Jul 2007, 20:54

I have a Optra sedan 1.6A,problem is jerking from N to D, it occurs sometime, to avoid this problem is just soft acceleration after N to D.

A way to safe FC is gentle acceleration and avoid traffic jam area, because this car is heavy, the FC will goes higher in this way.

My car FC about 9.5-10 km/L with 80%urban and 20%highway, I think is OK for this car.

I have an Optra 1.8LT too. I have it for almost 5 years now, and it seems to performed well so far. I have done some minor modification, such as K&N Air Filter, stabilizer, HID lights and changed rims to 17". Stabilizer will help with responsiveness. The petrol consumption is still very good, about 10 - 11km/ litre. The ride is still comfortable for such size rims. My highest speed I got on the speedometer was 192km. Note: I have a full body kit so that add weight. But so far so good.

There are some setback is you have to take good care of the car, and also need delicate handling and care. However, I guess it rewards you when you do that. The only problem I have with the Optra is the ride when I lowered it, and like everyone else said, the battery dies quickly.
