Reviews of Mobil parts For Business

Just get Mobil 1 0w-40 better then all of these

Mobil 1 fully synthetic, multi-grade oils only.

Mobil 1 15w-50

M1 fs 0w40 has been working well for me. But this oil does lose some of its viscosity after a couple track days.

I buy mobile1 high mileage 20k mile oil and change it every year (less than 5k miles per year on my G coupe)

Mobil1 0W-30 full synthetic. Just did my first 1000-mile oil change a couple hundred miles ago. Been using Mobil1 0W-40 on my 2011 WRX for 220k miles, tracked, autocrossed, and daily driver duty after 160k miles when I had a head gasket failure and I rebuilt the engine.

If it says 5W-30 then the Hella synthetic should be fine. Except you can do all the other checks yourself. If they will use your parts that is ideal, get a Mazda filter and something like Pennzoil Ultra Platinum, Castrol or Mobil1 synthetic if you can get that.

I personally use Mobil1 exclusively with 5-30 regularly and sometimes go a bit heavier in the summer or if I'm planning on operating in 'Severe Service' conditions

Im using Mobil 1 ESP 0w-30 which is a thicker Euro oil here in Upper Midwest USA. I don't notice any difference is sound, acceleration, not efficiency vs 0w-16 and 9w-20 in a 2024 Rav4 Prime XSE.

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.
