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.

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 .

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.
