Best oil for my Cruze 2011

mikinir said:

Hi all,
i have just bought 2011 automatic 1.8L cruze and i want to change the oil and filters.
i want to point i live in Colombia , the weather here is always around 26-30 celsius ( 78- 85 fahrenheit).
i have 60K km on my car ( 37k miles).
from what i read many put semi synthetic SAE 5W-30, However i went to the shop and all they had is MOBILE 1 FULL SYNTHETIC SAE 5W-30 oil.
is this oil is good? also is it very important to use the original oil and air filters or not necessary?
thanks

Fill any synthetic you can find. Some will have benefits over others. For example, AMSOIL's Signature Series will allow you to go 15,000-25,000 *miles* between changes, assuming filter is changed at OEM intervals. Other synthetic oils, just stick to OEM intervals.

It's not important to use the original oil and air filters. There are plenty of aftermarket options that are just as good or better. I prefer Wix for our car's filters.

Unfortunately, that oil is actually pretty bad for turbocharged engines. The EP formula does a very poor job of preventing deposits in turbo operating conditions. The standard Mobil 1 does better. For the OP, it would be fine since he has a 1.8.

Thanks, they do have mobile 1 fully synthetic SAE 5W-30 but i didnt found the one that you suggested ....i will keep looking...

Get a K&N air filter, don't forget the MAF sensor cleaner either!

Unfortunately K&N has been demonstrated to be pretty bad at particle filtration.

2 for 2 negative! To think this website is why I've gotten what I have! ! !

Both "negative" replies have factual evidence behind them. K&N filters pass 47x more fine dust according to ISO 5011 testing than OEM filters do. They just aren't good filters. They also clog to restriction with only 1/3 the amount of dust that an OEM filter can hold before it becomes restrictive. The oil's deficiencies were proven by AMSOIL's published TEOST 33C, an ASTM standardized test for measuring turbo deposit formation. While the API SN specification allows a maximum of 30mg of deposits to be formed, M1 EP barely passed with 28.2mg of deposits. That's no better than what conventional oils can do. Since that test was made specifically to measure deposit formation in turbocharged engines, the oil is poorly suited for the 1.4L Turbo in our cars.

The K&N filters are so bad that Dodge issued a service bulletin for their turbo charged diesels. This bulletin instructs dealership service departments to check for non-OEM filters (Dodge couldn't specify K&N for legal reasons) and if found then check the turbo for particulate scarring before doing warranty repairs.

Personally, I'd recommend a Wix oil filter and Amsoil Signature Series 5W-30.

Air filter I'd stick with OEM or equivalent. I used to be a big fan of K&N filters, but had never done a lot of research. Did more research and found out that they're generally considered to be absolutely terrible.
