Engine oil RED LINE or AMSOIL
Amsoil XL 5W-30 in my 2016. Swapped with a new OEM filter every 6K.
Completed my first oil change at 5k miles with Redline 0w20 and a Mann filter.
I had Blackstone do a Virgin Oil Analysis of Red Line 5w30 This sample of Red Line 5W/30 looks good in testing. The viscosity is just a little above our \"should-be\" range for unused 5W/30, but that's common to see with some brands, and it doesn't show any sort of problem or deficiency with this oil. The additive package is typical of Red Line. They use a lot of molybdenum anti-wear additive. There's also some silicon, which is good to know about since silicon can also show dirt in used oil samples. It's an anti-foaming additive. No moisture or solids were found. This oil is in serviceable condition.
FWIW, I've run AMSoil in my 2003 WRX since new, and I like it. What actually sold me on it was when I did my first oil change. The used oil still feels new when you run it over your fingers. And the engine still runs just fine.
I'm one of those people that uses Amsoil. I use their European 5w40 and change the oil every 10K or 1 year, whichever occurs first. Never needed to add any oil between changes.
I've run Redline in several previous vehicles.
Here is what I've been using on the Gen3 1.8t (2014 passat) - http://www.amsoil.com/shop/by-produ...otor-oil/european/european-car-formula-5w-40-synthetic-motor-oil/?code=aflqt-ea . Works really well with a 5K OCI.
Anyway, this guy starts talking about this brand, AMSoil, about how it leaves 1/3 the deposits of Mobil 1.
I use amsoil in my trans am. Never had a bad experience with any oil but everyone seems to love amsoil so figured it couldn't hurt. Especially with an engine that makes some power.
Just finally did my yearly oil change on my old faithful 04 wrx 177k miles last week. Put 14,370 miles on the signature series 0w40. Oil sample got in today. 31% oil life. Very little brass, relative clean oil. Waiting for my rod bearings to die but if this keeps up they might last a bit longer! Keep in mind I was using amsoils 25k mile oil filter aswell.
