(2 pack) Mobil 1 FS European Car Formula Full Synthetic Motor Oil 5W-40, 5 Quart

I use Mobil 1 FS, 5W-40 in my 6.2L super charged gasoline engine in my Tahoe. Very reliable oil. GM has changed their mind on the 0W-20 that they called for in the past. The improved gas milage to make the Federal Gov't happy was destroying the engine. It's no wonder that Europe didn't fall into that trap.

If you’re running a European-spec engine that calls for a 5W-40 ACEA A3/B4 or VW 502/505 rated oil, this is one of the easier decisions you’ll make at oil change time. Mobil 1’s European Car Formula has been in my rotation for a while now and it consistently delivers where it matters. Cold starts are smooth even on cooler mornings — the 5W winter viscosity does its job getting oil moving through the system quickly before things warm up. Once at operating temp the 40-weight hold is solid, and I haven’t noticed any consumption between changes which is always a good sign with a full synthetic at this grade. The 5-quart jug is the practical buy here. Most European engines run a 5.5–7 quart capacity so you may need a second quart depending on your application, but for a standard change this covers the majority of use cases cleanly. The pour spout is well-designed — controlled flow, minimal drip, no funnel needed if you’re reasonably careful. Engine noise at idle feels marginally quieter compared to some off-brand 5W-40s I’ve used in a pinch, which tracks with Mobil 1’s reputation for shear stability across the oil’s service life. If your car requires it, don’t substitute — run the right spec. This one does the job properly.
