Engine oil LIQUI MOLY or Shell

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.

The extra fuel is indeed from my mainly DD of the R, but using Rotella is just fine.

Rotella T6 5w40 in my R is running great

Just did the oil change last week... the 5w-40 didn't seem to like the unusually cold temps we had here over the winter... now that it's warming up outside the Rotella seems to keep a lot of the mechanical clatter of the engine down and it runs like butter.

After break in, I started using Rotella 5w40 synthetic, as I got better mileage with it. It's looking like a 5w may be way too thin for these old motors, and perhaps I should have stuck with a 15w40!

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 would highly recommend the Shell Rotella 5-40 full synthetic. You can get it at Walmart, $22 for 1gallon. It is designed for diesel engines and meets or exceeds the recommendation by VW.

VW uses Castrol Edge 5w-40, it's what they used for mine too, i do like Castrol but not the one made here in UAE(Sharjah), therefore on my RS6 i am using Liqui-Moly Top Tec 4100(VW approved 502, 505, 505.01) which is only made in Germany and i very happy with it, therefore i am going to use it for the Phaeton as well!

i know out of my positive personal experience with this oil and then every Blackstone oil analysis indicates low wear. i am a very satisfied customer which will only run liqui moly fluids on all my motors.

Mobil 1 lacks the zinc for sure! Many people I know in Honda circles have done alot of oil research, as the flat rockers pads of the H22 VTEC engine get eaten away, especially with high lift cams. Most of us now run either Brad Penn, or Royal Purple HPS oil. I run the Rotella T6 in my Subaru and Acura, but the older Honda engine I still don't trust it.
