Engine oil OEM Mazda or AMSOIL

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

They should be using 0W20 full synthetic oil (not synblend crap). Its not going to hurt running the 5W20 in it instead but next time mention it at write up. Mazda claims benefits such as better cold start protection and better efficiency among other things.

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.

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
