Engine oil Mobil or AMSOIL

I use the Mobil ESP 0W-20 in my Unitronic stage 1 Tiguan and it\u2019s solid.

Amsoil Signature 0-30 ,Tokyo Roki Black Japan filter only and 5000k, soon to be switching to 0-40

I’ve used Mobile 1 in all my vehicles. Never had problems.

Mobil 1 in all my vehicles recently. Basically only because it’s cheap on Amazon. Always paired with a Wix XP filter though

I have a 2012 Camry all 10k oil changes running Mobil one exclusively and it burns no oil with 270k miles.

My 05 Corolla had one oil change at 800 miles, one at 10,000 miles, and then once per year for 14 years until it was totalled at 330k miles.

I\u2019ve been using Amsoil Sig Series ever since my first break-in oil change. I used it in my old turbo Cobalt SS that I drove like a jackass when I was younger too. Never had any engine issues and Blackstone analysis shows that up to a 4,500 mile oil change interval is safe for my WRX.

Amsoil always over anyone. I started with AMSOIL in 2004 and after pulling my Hayabusa Engine @ 20k miles to build for a turbo kit, the engine teardown was perfect, the block, pistons and bearings looked entirely new.

AmsOil 10w30 for turbo engines... haven't had any issues yet. Still consumes it though.

I sent a few samples from my Ecoboost 3.0 to Blackstone Laboratories at 5k miles each. Mobil 1 and Pennzoil Platinum, both used Fram ultra synthetic filters.Oil was pretty much cashed out. I couldn't imagine going any further than 5k.
