2014 Corolla Altis - Technical, Features & Use

[Kklee]

Was taken by surprise by the price of trd oil. Anyway with the basic oil I can achieve quite good mileage so I just continue with caltex 95.

 

A friend said don't use caltex concentrate on old engine because the dirt may be blocking gaps and once remove can end up with leaky engine. Fairy tale ?

 

I use TRD engine oil for longer drain interval and cleaning properties.   Better FC is a by-product. 

What your friend had said, maybe. I had colleagues used on 8 and 9 year old car,  no issues.

 

IMHO, the whole idea of using fuel additives and quality engine oil is for preventive maintenance.

I guess there is different school of thoughts for that.

Been using it ever since my old mazda 3 with 190k mileage when i took over. From cranky noisy drive to a smoother feel. That's when i was sure such concentrate is good for both old and new engine.

Longer drain period = service interval ? Or you service the rest of the car without oil change ?

 

Btw is the CVT transmission oil change at every 40k km?

[Altis2016]

The Caltex Techron Concentrate?

 

Yes. I used Caltex Techron Concentrate.

 

Have to agree with ConnorMcLeod that TRD oil @ BM is expensive? I am not sure whether any AD in S'pore allow us to bring our Engine Oil. I am not sure which engine oil BM used but Kah uses Shell Helix for all their Honda cars.

 

I feel that the car is not so smooth after the travelling more 7000Km after each 10K servicing.

 

Definitation of smooth:

I used to drive to KL then Penang and back to Singapore. Everytime when I am back in Singapore, the car will be very smooth for a few days before it go back to its initial feel. People say it is the carbon.

You're right... it's the carbon build up...

 

Komoco allows you to bring your own oil in... so does Cycle and Carriage and does Motorimage...

The service interval is 10k

Depending on usage, an EO may not necessarily last 10k.

So, that's where a "better" EO comes into play.

 

Not sure CVT how many K at BM.

IMHO, either the EO cmi ( dependent on usage ) or the injectors got clogged.  

But after 8000km the engine free revving again? 

 

Likely is carbon build-up - drive more aggressive lor ! 

 

P.S.  Long distance and higher speed driving actually is much cleaner. 

[Altis2016]

Nope. The engine remain until same until the next servicing. P.S. 7000k is a rough guide.

Haha, I will try   next time more agreesive.

Svc centre says they use Castral but no details (in case there are multiple suitable Castral prifuCts available ).

 

Do u pump 98/shell ultra in MY n 95 in SG hrnCe 5ge diff?

This is Nick named Italian tuning. Allegedly for sports car svc they take it out for a hard drive n the high temp burns all carbon deposits in 5he system.

 

Last car I was suggested to lock in 3rd gear n drive a whole on NS hey to clean it. I never tried.

[Altis2016]

For my previous car, I pump shell 98 and it is more powerful and smoother. For this ALTIS, there are little differences.

I am just surprised that @ 20k mileage within 8 mths, carbon is already building up. Not sure whether Esso is culprit since the push and pull disappeared for me since I switch to Caltex.

 

If that is the way to clean carbon, then I will also not tried haha.

P.S.  my observation is that after the rough part,  the engine oil will start to break-down where the engine becomes rev happy and you'll get good FC. 

[Altis2016]

Noted bro, thanks for the input. I am still pretty happy with my average FC of 15.1km/l from Sept 2016 till now display by the car.

This is very good FC.

 

While for weekday I can achieve good FC between 16-20km/l, the short trips during weekend made my average FC below 15.

 

I noticed the FC drops very fast when I enter car park. This is a few Hundred meter drive for a 20km trip, the FC drops can from 20 to 18 (indicative only). Makes me wonder how FC is computed by 5he dashboard unit.

How long does it take to "run in" new eo? Castral to be precise.

That is what BM say and dont know why I complian about FC @ 20K servicing. I told them when I calculate manually, the FC is 13.5 to 14. AFter a 2 weeks, my computer FC display drop.

 

My computer FC display actually drop to 14.8 when manual calculation show 13.5 to 14. After changing to Caltex, it rise up to 15.4 for a while before stablise @ 15.1

 

P.S I have not reset FC since Seot 2016.

 

The better the FC, the faster it drop. That happen me to initially too. But now, i dont reset FC. I truy to find out how they calculate but no success. 

 

According to some report, computation by the car is most accurate. I notice something very interesting about my car recently:

 

1.) When top up full tank, cruising range show 731Km

2.) As u drive, total distance travelled & cruising range drop to 720++ km

3.) Continue to drop unit 3/4 petrol mark    

3.) Once pass the 3/4 petrol mark, total distance travelled & cruising range increase to 750km

4.) Continue to increase unitil 1/2 petrol mark  

5.) Once pass the 1/2 petrol mark, total distance travelled & cruising range start to decrease 

6.) When I top up (crusing range left 120-150km),  total distance travelled & cruising range aro 720++km

My dash says about 720km after filled up full tank. I will start to monitor how FC n total distance for tanks varies until next top up.

 

Could the variation you observed due to non squarish fuel tank not taken into calculation of remaining fuel ? Eg an inverted cylinder fuel tank a sensor dcalibrated for a cylindrical fuel tank, will perceive fuel runs out faster towards the end if tank n reduced FC.

 

Why are we debugging for Toyota ?

[Altis2016]

I guess it is due to the fuel tank. Just wondering if I always top up @ half tank, my FC manuel calculation would be fantastic.

 

Haha, we spent more time with the car then Toyota. If lucky, we get a service guy who also drive this model, then maybe he can share more.
