LCA Bushings vs Stabilizer Bushings

Its been about 10 months since I got my current ride. When it arrived, it has cracked lower control arm bushes and worn stabilizer bushes. The bad LCA bush can be seen visually but the bad stabilizer bushings can't.

I concluded this from the worn right hand tyres when I first inspected the tyres. My previous ride also had the same issue. You can read my "gluk" battle post for that story.

So when I got this X, the first thing I did was to immediately replace the stabilizer bushings.

After 15,000km and 3 wheel services later, I do not see any uneven wear on the tyres.

Is it safe to conclude that it is possible that you ignore the LCA bushings until a much later time?
If you are cash strapped, maybe. But if money and time are not an issue, please get those bushes changed out.

Change the bush at a workshop outside. If you do it back at Nissan, the will make you change the whole lower control arm. Thats going to cost a bomb ^_^

Downsizing Rims to Improve Fuel Economy ?

Here something I ran into. Maybe we need to consider a downsize at a time when our fuel prices continues to go up.

Car and Driver, a motoring magazine in the US conducted a test to figure out how much of a hit would fuel consumption take if the size of a car’s rims were increased or decreased. To make sure the rim size was the only variable, the tyre make was kept the same, tyre pressure was kept as recommended and tyre compounds were nearly identical. All tests were conducted using a standard Volkswagen Golf and all but the 15 inch rims, were aftermarket alloys.
The results of this test was as expected:
Rim Size (inches)/Overall weight (rim + tyre)/Fuel Consumption
19/24.5kg/(9km/L)
18/23kg/(9.3km/L)
17/22kg/(9.7km/L)
16/21kg/(9.74km/L)
15/18kg/(9.9km/L)

How to jump start a car with dead battery / Macam mana jump start ?

Recently had to jumpstart a car with dead battery. The maintenance free (MF) type batteries are notorious to just suddenly die without warning.

Here are my steps

1. Positive to Positive (+)
2. Negative to Negative (-)
3. Start Donor Car
4. Leave running 5 minutes
5. Start recipient car 
6. Leave running 5 minutes
7. Stop Donor Car engine
8. Remove Negative Leads (-)
9. Remove Positive Leads (+)
10. Car with dead battery should go to a shop to check out its battery as soon as possible.

Most instructions you can find online will tell you to connect negative to Ground (-).
Do you know why?

Fuel Trim Chart

I ran into a very informative chart at Eastern Catalytic Tech Tips.

I like this diagram they have.

X-trail: 02 Sensor

I was comparing the O2 sensor signals between the X and a i10. The i10 looks like it has a more healthy 02 signal.

When i floor the pedal, the O2 signal responds shows exactly as described in scannerdanner's tutorial. As for the X, there was plenty noise & deviation from the expected signal form.

Do i have a lazy O2?

Gonna need more tutorials........
