Engine oil Motorex or OEM Subaru
My '15 Forester will burn a quart of oil every 1000 miles if I run 0w20.
I switched to 5w30 and it's all good for 5000 miles
Well I decided to try Motorex on my F800 GS, bought the 4T Top Speed full synthetic, in 15W50, boy I cant help it but recommend this oil, the gearbox is so smooth and silky.
Well, some manufacturers do have way shorter oil change intervals than Euro manufacturers. The Subaru severe driving interval is 3000miles/6 months, and I do lots of short trips in a desert climate so I usually try to be around 3-4000 to stay on the safe side for warranty and whatnot.
I use motorex 30W in the air (or coil) side. The motorex is great stuff
Motorex 60:1 piston and rings go 180 hours with out issue, could go longer but i change it every winter, powervalve has yet to need to be seriously cleaned in 3 pistons.
I went with the motorex recommended oil. Worked great.
