      Hi all - just finished rebuilding my ABA for my MK1, and I am looking for advice on a break-in oil.

      Head was just refreshed and machined, new rings and main bearings down below. I also honed the bores with a drill.

      Thanks in advance!

      Break in oil is something of the past. Most [if not all] new cars have no break in oil and you just drive them till the next service.

      When I first started at the dealership in the 80's, they had an oil service due after 1k miles. Manual and differential fluids were changed too [as long as they were not synthetic].

      That said, it's a touchy subject just as breaking in the engine. There are many different ways and everyone believes they are right. So, if it was me, I would just get some cheap oil, run the engine at 3k-4k on the freeway [to seat in the rings] for an hour, then change the oil. Depending on what the use of the engine, I would use a good synthetic oil of your choice.

      Thank you! I very much appreciate it.

      I was planning on filling with a cheap conventional oil to seat the rings and run the motor in a similar way to what you described. Then dump it and go with the Mobil 1 that I like.

      Despite being fairly pedestrian, the motor lives in my track day car. It's very slightly modified for track duty...oil pan baffle, big external oil cooler, header, TT exhaust, TT chip, K&N filter, and no SAI/power steering/AC.

      My major concern is getting the rings to become friendly with the bores. Maybe I'll put on soft music while I break it in.

      If not using a specific break-in oil at least do a few hundred miles with a high ZINC content conventional oil such as Rotella T. But as stated you'll get varying opinions on this.

      To add some controversy, I wouldn't do that.
