Best Engine oil for Volkswagen Jetta

I like pentosin and motul

I change every 5K with Liquimoli 5w-40... I'd use 5w-40 over 5w-30, especially if you're doing any kind of upgrade to performance. Car will run a heck of a lot better.. 5w-30 is to thin when working an engine as hard as most of us do.

For my 2.5 engine, with +100k miles and a turbo, ive been using liqui moly with great success. It meets the 502 requirements, and it yields great results.

I did notice lifter noise with the 5w-40 so decided to go with Castrol Syntec 10w-40 and it made quite a bit of difference in quieting down the lifters. I use a Mann filter. After i get the engine flushed on my VR swap using ****ty conventional oil, i'm going to run Castrol Syntec 10w-40 in it as well. Lots of people recommend 5w-40 or 0w-40 for the VR but i've found 10w-40 works well and my oil temps seldom exceed 208*.

I used Amsoil 0W-30 Severe service oil in my Jetta 1.8T for the first 120k miles or so. No problems, mostly 5-7k oil changes except when I was commuting from Ct to Boston.

I had the same problem with my 99.5 VR. I now use 5-50, problem solved.

I agree with nickbeezy... Liqui moly is qualit oil... Its funny, the way i see it: it delivers better quality than expected... If you use the oil in addition to some of their additives you will notice impressive results. These results include a quieter engine, better mpg, better long term reliability, less oil burned, etc.

Well, I did mine last weekend with Liqui Moly 5W40 and I have to say that the car does sound better than with Mobil 1 5W40. It might be imagination, but that counts too, right?? LOL

Amsoil made the engine idle much smoother than any of the other oils have but every oil I've used but Mobil has been good as far as life and burn-off goes.

I did have a 1982 diesel Jetta go 435,000 miles on oem int. shaft bearings. I had access to a lot of free Amsoil back then....so, that may have helped. However, I think it over-lubed the cylinder walls though. Rings weren't exactly what you would call 'tight.'
