Engine oil Mobil or AMSOIL

I have 148k km of entusiastic driving w/Amsoil 5w30 Series 3000. The Ontario distributor actually rates this better than the Euro formula so I will keep using it.

I bought a case of Delvac1 5W40(4x4L) Synthetic at a distributor not too long ago for $128 tax included. On a side note, it was cheaper to buy the Delvac1 than the Mobil 0W40!

As for oil, I suggest using Mobil 1 0w40. They recently started carrying this in town and my mpg has improved with it.

I switched to Mobil1 5w-30 shortly after purchasing my 99.5 1.8T and I haven't had any problems, as a matter of fact my cold-weather starts noticeably improved and oil temperatures seem to be consistently lower during normal operating conditions.

AMSOIL BABY, all the way. 10w30 Turbo oil and filter every 12,500 or 6 months whichever comes first. Out performs all other brands!

changed my oil two weeks ago to mobil 1 5w30 and she runs very smooth

I switched to Mobil1 synthetic. The factory fill oil is 0w30. I replaced it with Mobil1 0w40, it complies with all of the specifications, and is not that expensive.

I've been using Amsoil on my '02 A4 1.8T. Converted it over as soon as I could b/c that little hamster gets hot during the long summers around here. Car doesn't burn a drop of oil, of coure it has only 29k on it.

I have been using mobil 1. Amsoil is very good also.

I would recommend using Mobil 1 0W40 with a Mobil 1 filter...noticed a great improvement, not only in the reduction of the noise, but the engine is quieter as well overall...
