Engine oil Mobil or OEM Honda

Ive owned four 5.7s starting in 2005.

Changed all of them with 5w20 full synthetic, no real allegiance to a brand, but always a major brand (Mobil1, Valvoline, etc); typically 5k - 7k miles  between changes .

2005 had 250k , burned no oil, died when it hit a tree

2006 had 240k, would use 1/2 qt over 5k miles after about 225k.

2013, traded in with 225k, burned no oil.

None of these ever had a valve cover off.  I purchased the 06 and 13 new.  The 2005 I purchased with 100k on it.

The 4th is a 2021 with 35k on it. So far, so good.

I've been running 5w30 Mobil 1 full synthetic on my 03 hemi. 238k miles and still running perfect with no tick.

Mobil 1 ESP has specs very close to Subaru Japans own Pleiades oils. Its got loads of great certs, is widely available, well priced and highly regarded by loads of people.

Go with whatever is easy for you to source and also meets the VW502.00 standard. I personally run Mobil 1 0w-40 or Liquimoly 5w-40, whichever I can get cheaper.

My 911 has over 100k, I switched to 5-w40 mobil1. I’m sure driven is fine too, but mobil1 is perfect and designed for our cars, cultists be damned.

Mobil-1 FS 0W-40 is a solid choice, and you can’t go wrong with it.

Mobil 1 0w40 FS , it’s the factory fill for the car and the best choice.

Now the easiest one to find that meets my manual requirements is the Mobil 1 euro formula that’s the cool green color. The back of the bottle specifically states it meets VW specs.

I typically use whatever is cheapest and proven oils for all my cars. I have an '08 2.5 and have been using T6 5w40, they typically run coupons for them for $20 or 25.00 for the gallon jug. No, it doesn't get VW's official stamp of approval but it seems to do pretty well in this application and seems quite popular amongst various other makes especially Euro cars that require a 40wt oil. Quite honestly, I'm pretty sure you can run a quality 5W30 in this motor, it is not anything special. I've run M1 0W-40 and although it has the VW spec labeled on it, my car always had a faint tick coming from the valve cover area (lifter?) when warm. It never did this with the T6 oil in it.

I use to use Mobil 1 Full Syth. and it was a mistake the \"knocking.pinging\" noise will also reduce using the right grade oil. Learn from my past experiences.
