Engine oil Mobil or Eneos

But if you want the short of it:

ANY high mileage full synthetic 5w-30 oil will do great. Mobil 1? Sure. Amazon Basics? Hell yeah. Wal-Mart's Supertech? Send it.

I dropped some 0W-30 Mobil 1 this winter, and my sol with a d15b7 loved it. Made cold starts very smooth, and noticed no reasons not to continue running it.

I've used only 5w30 full synthetic (usually Mobil 1, sometimes others) since I bought mine 15 years ago (D15B7). Using the high-mileage variety nowadays, supposed to help out the old seals etc. Just over 150k miles but engine runs very smooth so seems to be doing the trick.

I use Mobil 1 synthetic blend HIGH MILAGE 5w-30. I think the high milage formula is the best for these old engines.

Eneos 5w-30! Car runs like a dream

My G37x likes mobil 0w 30 car feels great with this oil

Super happy with the guys at PIA, and they use Eneos 5w40.

Been using Mobil1 5W-30 since 1998... GTI now has 232,500 miles and is smooth as silk. I do oil changes on the dot at 5K miles.

The part number they listed for each quart of oil was G-E55-540-1B-DSP . Look that up and you'll see why oil changes are expensive. Somehow I don't think the oil is better than the Mobil1 I buy at Walmart at $24 for 5 quarts.....

Recently got my first oil change at 5K and used mobil 1 0w40. The engine is now louder as compared to what it originally was. Not sure if it is the oil being too thin? or perhaps the cold weather.
