Engine oil Mobil or OEM Honda

These engines need 40w either 5w40 or 0w40.. I ran 0w40 Mobil 1 syn euro formula for the 60k miles I had my GTI, it's cheap and readily available in 5qt at Walmart, thinner on cold start up it when hot is still 40w, it's also the factory recommended by Porsche

Mobil 1 ESP 5W30 and Delvac 5W40 are right next to each other at Walmart and usually within a dollar of each other in price. Our 2 cars use Mobil 1 ESP and my diesel Jeep uses Delvac 5W40. Both are good oils, so I think it will just be your personal preference. Blackstone tests will tell you the story on your oil and intervals better than Reddit.

Mobil 1 Turbo Diesel Truck 5W-40 in an ALH since new. 10K OCI, engine with 280K running like new.

Mobil 1 ESP 5W40

Mobil1 is great oil and what I personally use.

One of my cars has 240,000 miles and burns 1/2 a quart in 10,000 miles using Mobile 1 5W-20

I buy Honda oil for my Honda because it came from the factory!

I use that same oil in my Honda NC750X DCT with good results so far (28000 miles).

Pretty pricy imo, used it once then when I consulted with friends/a family member I’ve decided to switch to Mobile 5W-40, as this helps with the temps in my area living in a desert lol.

We had a guy trade in a 10th gen Honda Civic with the L15BE (known for head gasket failure mostly) that he filled with thicker oil. Started knocking like crazy when we changed the oil for the sale.
