Hello everyone,

I have a 2.0l manual CX5 from 2012, with approximately 180,000 km.
I have bought it at 170,000 km and the dealership I went to did the oil change with 5W-30 oil.
My question is, what type of oil should I go for next time?
The technical manual gives 2 options: Supra 0W-20 or Ultra 5W-30, but doesn't say in what case to choose one over the other...
I have emailed to Liqui Moly to ask the same question and they reccomended Leichtlauf Hightech 5W-40.
And now I am confused.

Welcome to the forum.

I would first see what is available to you for your area.
Then you can choose a full synthetic oil (preferred but semi synthetic will work)
You may want to look at what the upcoming temperatures will be this winter in your country/
Then go to a general oil chart and pick a muti viscosity that will work for the engine operating the engine in the temperature range of your country.
Or you can make it easy and use 0W20 for the upcoming winter months and decide later if necessary to change oil viscosity for the summer months?

Auto manufacture oil recommendations are based on the most popular area that any given platforms are intended to be sold. That is why they call it recommendation and not required when looking at the recommended oil to use.

 

This is what the manual recommends, the car was putchased from Grrmany, but we have similar weather conditiona in Romania. Also, the mechanic sugested to use Metabond also.

 

The type of brand oil is only a personal preference form most mechanics. There is no advantage as long as it meets the requirements of the OEM. As I said it even okl to use a semi-synthetic motor oil if that is all that is available. The information provided by each person and the country they live in is a direct indicator that not all motor oil of high quality is available and are not necessary after your obligation to keep up with the warranty period of the vehcle. .
As for the factory service recommendations they were set up for the first 100k miles after which the better choice is to use an oil chart based on operating temperatures and specifications of the oil. Once out of warranty of it is better to choose parts and service that fit the operating environment and not to simply keep to the schedule for warranty purposes. This should translate to more frequent oil and filter services and more preventive maintenance.
