Engine oil AMSOIL or RAVENOL

i have used Amsoil for going on 10 years with great success. I have never had a problem or failure with anything i have used it in.

I used to use mobile 1 fully synthetic 5w 30 with a quart of lucas synthetic oil treatment and it work pretty good and i could get about 5k out of it. I just got hooked up with an amsoil dealer so im now using amsoil's european 5w 30 and im going on 7k and its still pretty effin clear

Been using AMSOIL since day one of my first oil change. Damn good oil.

The oil comes out cleaner with Amsoil. I also notice much less oil loss/evaporation with Amsoil compared to Mobil 1 or anything I've used. With Amsoil the level does not go down at all.

Here is an amoil oil test in Acura TSX. The 43150 mile test is amsoil series 2000, the 34000 mile test is mobil syn blend. At 5700 miles amsoil contained the same 7 parts of iron, that mobil syn blend contained at 3000 miles in the previous test. Thus about 1/2 the wear vs mobil syn blend. Damn good oil.

I've used AMSOIL since 1977....in everything from to name a few, my 83 GTi, 88 Scirocco, 04 R32 and now the wife's 06 Passat 3.6L as well as my 04 Volvo S60R and have never had an issue. I use the 5w40 in the Passat and 0w30 in my Volvo.

I have used Amsoil's 5w-50 on my mk4 GTI 1.8T and my Passat from their first oil changes until now. I love the oil and use it exclusively.

When I tried Amsoil in my 16v for the first time, oil temps were 10 degrees cooler on my MFA. I have Mobil 1 in now and my oil temps are back up 10 degrees higher.
