Engine oil Motorex or OEM Subaru

It works great, maybe a bit expensive. I've run used oil analysis and change it 3-4k miles based on aluminum wear. I don't see a reason to use something else.

I use Motorex semi-synthetic 4t in all of my KTM's over the years in a 15w50 weight. It has never been an issue. I have used Motul 5100 and 7100 in other bikes before, and I prefer the 7100 over the 5100. It feels like the bikes perform better when the temps rise and I'm really riding them hard.

Oil being dark is a good indicator that you have to do an oil change. However, you shouldn't wait until it changes color to do it. Clear oil doesn't necessarily mean you can keep going.

It is well established that boxer engines want their oil changed and I do not think for a second that a visual inspection is valid for determining if it is time. Highly, **highly** recommend you change the oil per the manual without hesitation and regardless of what it looks like.

Just came across this. Mine is a 2024 w 31 hours. I always used Motorex but I’m trying T6 this time. I use it in all my other off road bikes. In the 2t it’s just the clutch and trans. Also I’m changing it every 10 hrs

Ive used these. Motorex was the best. Castrol was pretty good, and Shell in case the others were not available. Now at 34k odo without problems.

I have always used Motorex. I have the same bike and 3 other KTM’s. Always Motorex. I know it is spendy but it’s very high quality

id put 17 at the okay point but any lower is not good - well my subaru would do about 18-17psi at idle so im sure alls fine

0w20 provides your engine with more wear protection .

There is minimal difference between 0w16 and 0w20, with 0w20 provided marginally better wear protection and 0w16 providing slightly better fuel efficiency since it's slightly thinner and provides less internal resistance.

I have a slow oil leak (something like a quart every 1,500 miles). Dealer quoted just under $3,000 for the fix when it was 17 years old with 110,000 miles. I'll just buy the occasional quart of oil.
