Totally agree with the sentiment here. If you're planning to keep this thing past the 100k mark, honestly, the most important thing for long-term reliability is cutting that drain interval in half. I’ve seen way too many EA888 engines develop oil consumption issues or carbon buildup from those 10k-mile stretches. Stick to a 5,000-mile cycle instead. Also, just a quick technical heads-up—double-check your under-hood sticker because most 2020s require the VW 508.00 spec specifically. That 0W-20 stuff might seem thin, but the oil pump and timing chain tensioners are literally engineered for that viscosity. Basically, as long as it hits that specific VAG approval, you're golden. Keeping it fresh is way cheaper than dealing with a turbo failure down the road, tbh.

Exactly what I was thinking

For your 2020 Audi Q5 2.0T, all three brands—Castrol, Mobil 1, and Liqui Moly—meet Audi specs and offer excellent protection. Audi recommends oil changes every 10,000 miles, but checking the oil condition periodically, especially under severe driving conditions, can be beneficial.

For your 2020 Audi Q5 with the 2.0T engine, all three oil brands you mentioned—Castrol, Mobil 1, and Liqui Moly—are excellent choices as they meet Audi's specifications for synthetic oils. Specifically, you'll want to look for oils that meet the VW 502 00 oil quality standard, which is common for Audi engines. Between the choices, Liqui Moly is often praised for its high performance in European engines, providing excellent protection and engine cleanliness. Mobil 1 is widely respected for its overall engine protection and availability, while Castrol is known for its strong performance in turbocharged engines like yours. Regarding oil change intervals, while Audi officially recommends oil changes every 10,000 miles, many Audi enthusiasts and experts suggest shorter intervals for optimal engine health, especially if you drive in severe conditions or have a heavy foot. Changing your oil every 5,000 to 7,500 miles can be a safer bet to maintain engine performance and longevity. Always ensure that any oil you choose is compatible with Audi's specifications, and keep good records of your maintenance. Regular oil changes are crucial for keeping your Q5 running smoothly for years to come.
