Engine oil LIQUI MOLY or AMSOIL

No warranty here (MKV), but i experienced a (significant) decrease in oil consumption, when switching from Motul, to MolyGen. YMMV.

I only ever use Liqui-moly and Mann filters on these cars. This past weekend, I cleaned the hell out of the interior.

I originally ran 10k intervals as recommended by VW. Early oil changes were done with Castrol Edge OE 5W-40(exact same type the dealership uses) Later on I thenswitched to Liqui Moly 5w40 Leichtlauf high tech and began running at 5K intervals after reading quite a bit about the 10k intervals being too long.

I only ran liqui moly in my TDI and have been running it in my R since I bought it. IMO they are one of the best brands.

The liquimoly additive, Oil Additiv p# 8352, did help me for a bit but now it's back to the usual oil guzzling. For my choice of engine oil I use 5W-40 Toptec 4100 liquimoly .... I think it reduced consumption somewhat over OEM castrol.

I have the cr150 tdi and am running liquimoly 10w60. Have not used a drop of oil running the cr190 turbo. Oil is just starting to grey ( diesel thing) after 5500 miles. 0w-40 505 mobile was burning off on me and god forbid pentosin 5w-30 507 smoked like a chimney - I got multiple engine lights having to pull over and undo the cap with the engine running, downright embarrassing. Going to attempt amsoil (not going Walmart mobile 15w-50, give me liquimoly) 5w-30 diesel and see how that works. 15w-40 works great but still barely makes it to 10k for me. I am finding it hard to run gas/diesel oils like liquimoly without a 5k interval, 7qts of liquimoly 10w-60 for $65 Amazon. Practically have to run strictly diesel specific for me, hard to find heavy duty synthetic diesel oil at common shops sometimes.

Neither Castrol (OE - 5-40, or 0-40), or Liquimoly 5-40 burned a SINGLE DROP in about 5-6k miles!! Why would I buy a \"High performance\" oil, only to constantly need to top-off, like I own a crappy Harley. I never follow the crowd, Mobil included. Liquimoly and Castrol are great. Someone else made a great point. When do you ever,.....EVER see a car die or even have ANY issues caused by oil. My father had a car last 260K miles on absolute garbage oil from LubeXpress (Last meaning he donated the car with 120LBS compression, each cylinder). You will DEFINITELY see issues in your Transmission, clutch, suspension, RUST, steering, interior finishes, etc. before you will EVER see an issue related to Oil. Picture all the fox-body mustangs that are absolute TRAIN WRECKS...that still run and have power...but everything else is destroyed THAT SAID...Just make sure to use a VW spec oil in your TSI. Coking of turbo's is no joke.

Started using Liquimoly 5w-40. Wow what a difference! 3/4 qt. per change cycle. There really is a difference. Same spec as the others though.

I replaced the cam adjuster magnet and haven't had a problem since and I changed the oil( I used liqui-moly this time).

Last change I did I switched to liquimoli 5-40 and I used a can of Cera tec. Noticed a bit of quieting from the engine after a few miles of circulation and after nearly 5k miles I'm only down mayyybe 1/4 QT. So far so good at 131,000
