Engine oil AMSOIL or ZIC

Amsoil 10-30 was my choice on my 200,000 mile 2001 jetta + i changed @ 10,000 usually 4 to 6 months. car was chipped etc, about 300 tq + 275 TQ with a KO-4 + APR tune etc.

AMS oil 5w40 "European Formula" after first 5k. Just dumped the first oil after 10k of hard driving. Still had lot's of life left in the oil, and no noticeable consumption as we recovered almost all of what was originally put in (4.4 of 4.5L)

For what it's worth I run Amsoil 20-50 in both holes on my 01 sporty 1200, never had any issues.

AMSOIL is good stuff, but it's expensive.

In my last four VWs I've run the Amsoil 5w40 Euro Spec oil and think it is good stuff. My 1.8t engines in my old Passats ran really quiet with this oil. I changed the oil in my GTi at 2500 miles and switched to the Amsoil and have had no complaints. I'd recommend Amsoil.

I also use Amsoil European Spec Mid-Sap 5W40 approved by VW

Amsoil 10w40 and there 20w50 non race oil it says right on the bottle it has a heave zinc compound for extreme use. I use the 10w40 in my Rocco 16v my wifes mk1 gti , and a lot of other vehicles. No upper end noises on any of them. Worth it weight in gold!

I've been running the AMSOIL 5w40 in my cars exclusively for the last 5+ years and it has lasted well and held up to abuse as well.

For those of you having a hard time finding VW spec. oils and you desperately want to stick to the 5w-40, try your local lawn mower, or small engine repair shop. In my area only they stock the 5w-40 synth. VW 502.00 oil - they used to get Elf/Total, but recently moved to Amsoil.

I've been running 12k-20k, oil & filter change intervals with Amsoil since 1978 (mainly in VW/Audi engines) and have never come close to wearing out an engine. When I sold my 1990 Audi 100 with 260k miles, it was still only using a quart of oil in 10,000 miles.
