Engine oil Shell or OEM Volkswagen

Rotella T6 now comes in 10w-30 as well as a 5w-40 both are excellent choices.

I'll always use T6 because it's cheap, available, and damn good oil

The interesting part is that the T6 was used to tow a camper from Indiana to the Oregon coast where we are now. It’s interesting to see the viscosity, flashpoint and Moly are higher in the T6 even after towing through the mountains and more miles on the change.

If you are using VW original oil then stick to it and the service interval. 15 years 229,000km later mine is going strong. I did mess up by doing service at 15k km all these years. Sticking to 12k is best. Instead try iftex system D. Makes a very noticeable difference. More important I feel is changing the air filter more often. And compulsorily changing diesel filter every year.

Been running 87 and 5w 40 on my mk7.5 for the last 40k of ownership. She loves it, no tics stutters or hiccups at 65k miles.

I wouldn’t go with 0W20. Most people thicken the oil up in these when they start getting excessive oil burning. Lots of folks running Rotella 5W40. I ran it for years before I got tired of paying the premium price.

I run rotella t6 5w-40, and she loves it

10w30 Rotella will cut your oil consumption by 70-80%, ran it in my last Subaru until the clutch went at 234k and running it in my current Subaru

Vaguely remember having the oil and brake fluids changed for my 40k, and maybe a tire rotation.

Using the incorrect oil can cause damage and will definately void your warranty. Call the closest dealership and buy the oil for this oil change.
