Engine oil PETRONAS or OEM Volkswagen
Part number for the oil: G055512A2 $14 (x2) O-ring: N90362001 $4 (x2) Paid ~$38 total Yeah my dealer is about 40 minutes away so I bought two in case I want to order oil in the future and do this again sometime...or if it leaks for some reason and I have to drain/refill, I just didn't want to drive back.
Put 100k miles on my mark iv jetta tdi while using the stuff. No problems.
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!
The 5W30 full synthetic engine oil works the best for a wide spectrum. Its working temperature range is practical for daily use and it costs less than 5W40.
I bought a 153K kilometer 81 1.6 GTI and drove it for work to military bases all over Germany. With no restrictions I ran 160-190 kph as much as possible for a few hours at a time. It always used a little oil but I kept it changed with 20W50 dino oil and sold it at 280K still running fine.
36k miles and still not burning a drop between 10k OCI's. I use VW 0W-20 Full Syn 508/509 spec each and every time, until mobil1 releases a Full Syn clone. Noticed a "slight" increase in MPG's with the newer oil.
My giulietta 1.4 MA is still reliable at 130k km. Never had any problems with engine always used recommended petronas oil. Had to rebuild my turbo once (at 120k km) it had very little play that made my car burn some oil.
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.
Hmm... I just took the car in for its MoT and although it passed, they noticed that the exhaust was smoky and that oil level had been overfilled. The oil was last changed at the car's 40,000 mile service by the same VW dealer and on the invoice they've listed 9 litres of oil.
