Engine oil PENNZOIL or AMSOIL

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.

i run 5-40 amsoil in my VRT as well

I use Pennzoil Ultra 5W-40 European formula in both of my GTI's and use only oem filters (which are very good btw).

It's a little more pricey but extends change intervals and has worked for me. Keeps engine temps a bit cooler as well.

Now i am referring to amsoil, Delo 400, mobil one turbo deisel truck oil.

in my Diesels i use amsoil or chevrons delco synthetic for heavy duty diesel engines.
