Engine oil Shell or OEM Volkswagen

On an old e36, 5w30 full synthetic no matter the brand would often cause some leaks. Switched to some thicker Rotella oil made for diesels and suddenly no more leaks.

Worry less about the now old 502.00 spec than the actual oil itself. It's API SN/CF and has MB-Approval 226.5/ 229.31/ 229.51. Even though 505.00 and 505.01 are diesel engine specs, it should be fine in your older car. One of my go-to oils is Shell Rotella T6, which is specifically for diesels, but it's a great oil.

Its honestly all good, I ran Rotella T4 for a while, still good.

I'm a big Brotella Bro. I've used Rotella T6 in my WRXs, Miata, sport bikes, and dirt bike.

I suggest running Shell t6 5w40

Rotella 15-40. FTW

I run this one in our 04 BEW TDI. No issues what so ever!

The oil spec for the 1.8L engine in my 2019 Golf Sportwagen S 4motion is 502.00 (5W40). After my last oil change at the dealer I questioned whether they used the correct oil because the service ticket was written up wrong. The dealer supplied these photos to show how the different grades of oil are actually different colors. The oil on my dipstick was caramel colored, so I knew it was the correct grade for my car after all.

That PN is listed as genuine Volkswagen oil for your vehicle. You’re all good!

We had 50700 VW spec oil in for 4,000 miles on the oil and 4,700 miles on the engine. The iron wear rate was about 15 ppm/1000 miles. The Longlife III oil did have impressive viscosity holding charictaristics. I did not care for the way the oil film of the 50700 wetted surfaces, it fisheyed on plastics.
