Engine oil AMSOIL or Motorcraft

I use AMSOIL 5W-30 for both of our vehicles. Never had any issues on either vehicle using AMSOIL.

Amsoil Signature 5w-20 + K&N Gold oil filter (HP1017 for 4th gens, not sure about 5th) is arguably the single best combo if you can afford the oil. Your lobes will thank you.

The first thing I did was change the oil using a wix filter and Amsoil signature series 5w30. The verdict is that the oil has plenty of life left and could have easily run longer.

Amsoil W20 I got a 5.7 it’s been great to me

Amsoil Signature Series 0w40 is an outstanding oil I run it with the SRT filter.

I am a big fan of amsoil. I purchased a used F150 in 2012 . It had 80,000 miles. The first thing I did was I changed the engine oil, tyranny fluid, and front and rear end lubs to Amsoil. It now has 242,000 miles and just keeps on running.

I have used Amsoil for years and I change my oil every 15,000 to 20,000 miles.

Amsoil 5w-40 in my 3.6 Corrado that gets pushed hard to redline often and has seen somewhat high oil temps when driving harder. I use liqui moly 5w-40 in my 3.6 CC and 3.0T Q7.

I used Amsoil 5w40 European Car formula or Gulf 5w40 Formula G in my A6 previously. Technically Amsoil doesn't have the have the VW 502 00, 505 00 certifications so I think I will start using Gulf Formula G or GX exclusively in my R, either the 5w40 or 5w30 grade.

im actually running that oil right now... I hate it tbh. 3,100 on the oil and it has allowed excess engine noise since day one, SUPER harsh cold starts, and now its burning through faster than the catrol I ran when I first got the car. a WHOLE QUART over 750 miles. the oil is thinner than piss going in, and it just doesnt stand up to what my engine can put out like Shell Rotella T6 has been doing...
