Audi S5 (2017) - Which Shell oil to use?

[westlondonsun]

Newbie here .. Hi.... I live in UK and own an Audi S5 Sportback 3.0TFSI (2017).

 

Car is no longer under warranty and want to move away from 0w20.

 

I can get engine oil from Shell via my company fuel card.... from Shell ...they sell these two: 

 

Which of these is right for my car ? 

I drive my car :

- Mostly on motorways

- Don't drive too spirited (only occasionally, never track day etc ) 

I'm not concerned about fuel economy or frequency or engine oil changes.

Want to ensure I give the engine the best protection.

Which of these do you recommend? 

Shell garages near me usually stock 5W-40 in 5-litre containers, while 5W-30 is harder to find. I'd prefer using 5W-40 since it's more convenient to buy, but if 5W-30 is significantly better for the engine, I'm happy to travel further to get it when it's time for an oil change.
 

Thanks in advance for any replies. Hoping to buy on Sunday so hopefully someone can advise before then.

Welcome Parm and thanks for joining. 

So why do you want to move away from 0w/20 if ( in caps) this is the grade specified in your handbook or some other official VAG publication? 

As well as the grade, there will also be a VAG specification within that grade which the necessary oil must specify - as they say on the tin. 

Although I use the correct grade of Shell Ultra for other cars, I only use VAG’s branded oil -Quantum- in our 176K A3. In case it helps, I use their Longlife 3 ,but treat it to an annual oil change irrespective of the much lower mileage covered annually. 
I usually buy from reputable sellers on eBay. 
Kind regards,

Gareth.

In all honesty it's because 0-20w is such a low viscosity oil. Been reading up in numerous places that if the oil is thicker it lubricates the components of the engine better. Main reason for 0-20w was more to do with emissions and fuel economy which if I'm honest is less important..I'm more concerned about the long term health of the engine .

Taking your belief that if oil is thicker it lubricates better -if so, why not go all the way and fill the sump with grease! 

Deviating from the manufacturer’s recommendations is entering a territory you should not want to be in, but it’s your car and your choice to ignore VAG’s advice and the advice offered on here so far. 

Good luck with whatever you choose to do, and I remain happy that the advice I’ve offered you is based on sound logic. 
Having said that, please let us know what you eventually decide Parm.

Regards,

Gareth.

Thanks Gareth. I'll consider this in my decision. I'm complete novice so will take advice given from experts. 1 up on the 0-20w in which case.

No problem Parm, but if you decide 0w/20 is the way you will go, it won’t just be any 0w/20 - or necessarily a Shell brand because you can get it at a discount - but it must be confirmed to satisfy whatever VAG’s specification is within that grade.
