FYI, there are reasons people choose different oils. Let's take 5W-30. Simply put, the 5W part is the viscosity of the oil when cold, and the 30 part is the viscosity of it when hot. 0W is thinner when cold than 5W - modern Euro engines don't tend to do well with heavy, thick oils at a cold start. However, whether it's 0W or 5W in the UK won't really make much difference. The 30 part, the weight when hot, is more important. For example, my vRS runs on 20 weight, whereas most people like 30 or 40 weight. The thicker the oil is at temperature, the more protection it provides. In theory. The thinner oils are, really, used to help with emissions - thinner oils are more economical. So, who cares about emissions, let's just put a heavy weight in to protect the engine. The issue with this, however, is that it's not so simple. VW aren't stupid, and the engines have been adapted to run on this thinner oil - stuff like the variable oil pump has been optimised to run on the 20 weight at operating temp, and tolerances are also optimised. Sure, 30 weight offers better protection in the crankcase, but at what cost to the tighter tolerance bearings, etc? In reality, a thinner oil allows for a higher flow, which makes maintaining pressure easier. Less thick oil or more thin oil - same thing, really. My car is/was tuned and does get driven hard. I debated long and hard (just ask @Ootohere) about going to 0W-30, but decided in the end to just stick with what Skoda recommend. I even reached out to several (respected) VAG tuning places and they all said to stick with the recommendation from the manufacturer. The difference in protection might mean my engine has issues at 150,000 miles versus 165,000 miles - but I won't have it then. Sure, the difference in oil might make a difference (for better or for worse) but I don't believe going from 0W-20 to 0W-30 is going to make any huge difference. People use thicker oils as 'thinner oils are rubbish and offer no protection - it's all emissions crap'. Not all of this is untrue, but without being on the design team at VW and knowing exactly what changes were made to run on 0W-20, 0W-30, or whatever, I would just stick with the sticker. VW seem to have learned from this, as the earlier EA888.3 ran on 5W-30 and now the EA888.4 Evo runs on 0W-30, however I'm not losing any more sleep over it. [disclaimer for all the... people... on here - as mentioned above, many things are a generalisation. Talking about viscosity grades and centistokes probably isn't going to help OP.] Oh. Get VW spec too. There is a difference between an oil being suitable for the specification and being approved for the specification.
