Owner reviews for engine oil

I have never seen my 2017 Jetta low on the dip stick. I usually change it about every 5k miles using Mobil 1.

I've always run Castrol with no issues. The biggest thing is to make sure that whatever oil you use meets the spec required by your engine.

LiquiMoly!!!! Ask NGP in Maryland. They built my motor 7 years back. I used Mobil1 for 20 years. It's good stuff. But LiquiMoly is the ticket for me now.

I change my oil every 5k miles on my '18 C300. I work at an indy shop so I pay for wholesale dealer parts only. But my oil comes out golden and clean and I sleep better at night.

In Germany we driver Ravenol RCS 5w-40 and Archoil 9100....sick combination. i drive it in my c63s and gle63s and volvo S60....

I suggest you to use 5W40. I have a Toyota Auris and i change them every 7.500km without filter change and at 15.000 km with filter change. In my city at summer the temperature is about 40°C on summer and I have 257.000 km. I haven't any problems till now. My engine running smooth and never burned oil.

I use Castrol GTX full-synthetic 10W-40, as I live in Texas where the average temperature is hotter than the rest of the US and oil weather varies drastically. During the summer, I've considered bumping up to 15w-40 due to how hot my startup temps are on a "cold start".

Pennzoil ultra platinum often goes on sale or has rebates, I'll stock up a couple years supply when it does.

I've personally run Mobile 1 full synthetic for 10k intervals ever since the factory oil changes ran out without issues.

I'm using amsoil 5w30. Great product. Real synthetic. Superior protection.
