Engine oil AMSOIL or ZIC

I've been told the magic elixir for the VR is 20w50 Amsoil Not sure I can verify that just yet but my VR is a bit quieter with it since I added it

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.

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've been using amsoil for the past 2 oil changes. No complaints, car seems to idle a little better and cold start sooner.

I also started using it in my bike after switching from Mobile 1, and it's the best thing I've experienced so far with the wet clutch, keeping the shifting very smooth.

I just changed the oil in my car and I used Amsoil 5w40 European blend. No complaints so far.

I wouldn't use anything other than Amsoil I recently purchased some to change my R's oil soon.

Yeah...same reason I switched. I love Amsoil...and so do my engines trannies and diffs. It just gets too expensive using the Amsoil engine oil with the oil change frequencies that I use ( Every 8,000KM ).

Rotella T6 here. I was a long time Amsoil guy, but it's just too fracking expensive, especially with the amount of miles I drive a week.

I'm running Amsoil in my 06 GTi and loving it. No trouble with that I can tell, I check dipstick every fillup occasionally have to add some but not a quart, not even .25 of a quart. I've got almost 72k on the clock I did my last oil change around 67500 maybe a little more, and oil is still clean. Car sounds no louder or different from oil dealer had put in it.
