Engine oil Mobil or PENNZOIL

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.

I’m using penz plat though I’ve only had my oil changed once (3500 on my OD) but so far so good. My oil temp stays around the 200 mark once fully warmed up and has been running very smoothly.

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

The data I've seen round the web, including BITOG forums says that Pennzoil Platinum and Pennzoil Ultra Platinum 5W-30 is as good or better than the waaay overpriced Motul stuff.

Motul xclean, amsoil signature series, valvoline max life, and penzoil ultra platinum are the favorites.

Ive only bought at walmart. $21.97. My turbo calls for an ingredient thats in the pennz synthetic

I also found out the filter (Mobil 1 extended performance) was about $6 cheaper there too

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.
