Engine oil AMSOIL or OEM Subaru

From wear ratings and certification Amsoil, Pennzoil Ultra Platinum, Mobil 1 (Extended Interval). Amsoil I only use for track days, since I swap the oil out at 3.5-4K.

Real synthetic oil is way better than regular oil. Even full synthetic oil is better than regular oil. But if you want the best oil for the money look into Amsoil signature series. This oil is a true 100% synthetic oil and will prevent wear and quiet an engine down better than regular oil. I had a lifter tick in my Volvo 850 and it was caused by the pickup tube seal wearing away. I put Amsoil signature series in it and the film strength of the oil was so good it stopped ticking for a year before I had the seal replaced.

After 12 years and 45K miles. I took a 05 Mustang and added a supercharger. For the next three years , and 15K miles, I took it drag racing and high performance track day driving. Wanting more horsepower, I had the engine rebuilt with forged performance parts. When the engine builder measured the wear in the block, everything was still within factory specifications. I had used Amsoil for the life of the car.

personaly I use 5W-30 Amsoil, MANN oil filter and Hengst air and cabin filters

The best talaga ang [Amsoil](https://s.shopee.ph/7KbSRUV7OC)! Tested ko na sa car, bigbike at smallbike. Ramdam na ramdam ko pagiging smooth ng engine after magpalit.

Using 5W30 since deleting the MDS system from my engine. Amsoil Signature, every 6 months or 8000 km.

I called Amsoil and asked about this many years ago. They said for *my* bike, with the 5 speed tranny, they recommended the same 20w50 in all 3 holes.

I would also make sure that every time you fill up the gas you check the oil dipstick and if it’s a little low top off the oil. In fact, I think this is probably crucial to owning an older Subaru like mine mine has 300 K.

I second those saying bring a spare quart of oil. I wouldn't be too worried about taking my 2012 Outback at 170K miles on such a trip...but would agree check the oil every 1000 miles or every morning (depending how far you go in a day) just to make sure it isn't getting low.

I use Amsoil. While not on the official VW list as an approved oil, it is never the less formulated to the VW spec.
