Engine oil Mobil or OEM Subaru

If I could only have one oil for all my vehicles it would be Mobil1 0w-40 because it meets all the stringent European requirements and has been shown to have a cleaning effect on dirty engines.

Mobil 1, best all around protection. Especially under high heat/Cold conditions. Been running is forever in my cars

So I’m in the U.K. and I just had my car serviced it’s an x4M, the reccomend is BMW or Castrol Edge, I went for Mobil 1 0w-30. For some reason not sure if it’s the oil my fuel economy has gone up by 100 miles per tank

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.

Check all your fluids ASAP. If any are low, top off as per the manual and monitor closely before you leave to make sure it's not leaking or consuming anything. Definitely bring extra oil, 1 or 2 quarts would be pleanty, and some paper towels and rubber gloves help too.

Should be fine, but CHECK THE OIL FREQUENTLY. This series of engines is notorious for oil consumption problems, which may not appear at all when doing short trips, but suddenly it's drinking 1qt or more per 1000 miles on the highway.

Take a quart of oil with, especially if you don't have reliable data on how much your engine burns. Check it occasionally and top off if needed.

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 stay away from Mobil 1 and Castrol because although they are everywhere they are not as good as they euro synthetics. In Europe they are not even legally considered synthetics. When I drain mobil1 it looks black and the engine is missing a quart...
