2006 Corolla CE Automatic

I'm trying to get a good Engine Oil for performance/protection.

so what engine oil is suitable for the Corolla? Do I only get 5W30 engine oils?

and what brand is good? or is it just rather Synthetic or just regular oils?
~~~~~~
I basically want good performance but still can run 5000km like conventional oils.

How about transmission oils? is there other kinds which effects the performance?

thx.

5W30 or 5W20 are both acceptable. Good brands are Castrol, Valvoline, Mobil 1.

All 3 make good oil, either conventional or synthetic.

As long as you change your oil on time every time, then even conventional will be more than adequate.

Transmission fluid, I run Redline synthetic. Good stuff.

I personally use

Mobil 1. When I changed my 2006 corolla sport over to Mobil 1 synthetic I felt the difference. I haven't used the other oil products.

i'd go with mobil 1. i use that on all my cars and have no problems. I'm always beating on them and they work fine. as for the weight i really just go ahead and put what ever the service manual says comes from factory

So is 5w30 synthetic gonna bring out the most power out of the corolla and give good engine protection??

No, it won't give your Corolla more power. But it will make it last longer when changed regularly on time.

So no engine oils can give corolla more power?

unfortunately, no.

the viscosity you choose, however, will have an effect on how efficient the engine will perform.

one way to determine this is by comparing the cSt figure @ 100ºC of oils you're cross-shopping.

most manufacturers will list their specification sheets online.

Okay, I guess I'll go for mobile 1.

Thx for all the helps. : )

As long as it's what is recommended from the manufacturer - that is what you should use. 5W-30.

Mobil 1 is fine, but I heard that they no longer are considered a "true" synthetic oil as they supposedly went the Castrol Syntec route and cracked a few carbon molecules and called it synthetic.
Anyway, I have used Mobil 1 synthetic (not the EP version) since when I 1st got my car (Matrix, but with the same engine as the 9th generation Corolla) and it has been good.

The last year I noticed though the engine wasn't as smooth as when I 1st started using Mobil 1. Then I researched about the Mobil 1 oil shortage in some retail stores and decided to try something else.

Used Valvoline SynPower and immediately noticed the engine was smoother and quieter as compared from before.

I can only relate my experience, but I am sure whatever oil brand you choose, would be sufficient for a daily driven vehicle.

+1

I used to use Mobil 1 as well and noticed that my engine was running a lot noisier than it was even compared to when I was using conventional.... needless to say I switched oils after that. I'm currently using Castrol Syntec myself and the problem is gone. I think the problem with Mobil 1 is that it shears down to a lower weight oil really quickly.

I tried Mobil 1 once in my minivan and it quickly proceeded to generate a lifter noise. So I switched THAT out quick. I don't use synthetic oils anymore in anything. Any API-SM oil will protect your engine for the long haul. Go to BITOG and pour over all the used oil analyses and do your own cost/benefit calculation. For me, it's conventional oil on 3-5k mile intervals.
